Background: Enzymes are crucial for all aspects of metabolic function. Digestive enzymes from natural sources have been credited with beneficial effects in the digestion and absorption of food. N-SORB is a novel KD120 multienzyme complex (MEC) of metabolically activated enzymes composed of proteases, amylases, lipases, alpha-galactosidase, and glucoamylase from natural sources. These enzymes are encapsulated in a SK713 SLP (non-GMO soy lecithin phospholipid) absorption technology (Prodosome®). Objective: This randomized, double-blind placebo-controlled investigation assessed the safety and efficacy of N-SORB KD120 MEC in healthy male and female volunteers on various parameters of the blood, immunity, body composition, physical health, and quality of life following a 90-day intervention. Methods: Forty-six male and female (mean age: 25.8 ± 12.1 years) healthy volunteers were randomly assigned to receive either N-SORB (1 mL, twice daily) or placebo for 90 consecutive days. Complete blood count, as well as blood glucose, liver enzymes, and lipid profile were assessed pre- and post-intervention. Serum cytokine levels were determined by using a Bio-Plex Pro Human Cytokine 8-plex assay and enzyme linked immunosorbent assay (ELISA). Whole body composition analysis was performed by dual-energy x-ray absorptiometry (DEXA) to determine body fat mass, lean mass, and android and gynoid fat. Body weight, blood pressure, and physical health were assessed. Changes in quality of life were examined using the World Health Organization Quality of Life-abbreviated version and sleep quality was assessed using the 24-item Pittsburgh Sleep Quality Index (PSQI) questionnaire. Adverse events were monitored before, during, and after completion of the study. Results: Of the 46 subjects enrolled, a total of 40 subjects successfully completed the study. Compared to placebo, changes in blood cell counts including hematocrit, hemoglobin, mean corpuscular volume, platelets, and lymphocytes provide evidence of some improvement. Quality of life (QOL) parameters showed a small but significant improvement in the N-SORB group. A significant increase was observed in aspartate aminotransferase level in the placebo group at the end of 90 days of treatment; however, no increase was observed in the N-SORB group. No significant changes in blood urea nitrogen, serum creatinine, alkaline phosphatase, alanine aminotransferase, and lipid profile were observed between the placebo and treatment groups before and following intervention. No adverse effects were reported. Conclusions: This randomized, double blind, placebo-controlled clinical study demonstrates that short-term intervention with N-SORB improves the QOL and PSQI in healthy volunteers and did not significantly alter cardiometabolic parameters, lipid profile, or body composition.

Telomerase in T lymphocytes is dynamic and limited evidence from epidemiological studies indicates that the enzyme can be modulated in peripheral lymphocytes by dietary and lifestyle factors. The differential effect of dietary intervention on T cell subsets has not been investigated so far. Brassica vegetables are known for their multiple beneficial effects on human health, and here, the effect of a five-day short-term intervention with raw or cooked leaves of Brassica carinata on telomerase activity in CD4+ and CD8+ T cells from 22 healthy volunteers was investigated in a randomized single-blind, controlled crossover study. Blood samples were collected before and after intervention, and CD4+/CD8+ T lymphocytes were isolated. Telomerase activity was quantified using the TRAP-ELISA assay. Intervention with both preparations led to a marginal increase in telomerase activity of CD4+ cells compared to the baseline level. In CD8+ cells, a significant increase in telomerase activity (25%, p < 0.05) was seen after intervention with the cooked material. An increase in telomerase activity in CD8+ cells of healthy volunteers could be regarded as beneficial in terms of helping with the cell-mediated immune response. Whether a Brassica intervention has long-term effects on telomere extension in specific T cell subsets needs to be determined.

Abnormality in glucose transporter type 4 (GLUT-4) function and insulin secretion are the main causes of type 2 diabetes mellitus (T2DM). Due to adverse effects of antidiabetic drugs, nowadays, nutraceuticals have been of much interest to investigators. The aim of the present study was to determine the effect of pomegranate seed oil (PSO) on the GLUT-4 gene expression and glycemic control in obese people with T2DM. This randomized clinical trial was conducted on 52 obese type 2 diabetic patients for 8 weeks in Tabriz, Iran, in 2018. Patients were divided into the intervention group (n = 26; who consumed daily three capsules containing 1 g PSO) and the placebo group (n = 26; the same amounts paraffin). GLUT-4 gene expression and glycemic indices were evaluated by standard methods. GLUT-4 gene expression was increased significantly in the PSO group. Within-group changes in fasting blood sugar (FBS) and quantitative insulin sensitivity check index were significant in the PSO group. After adjusting the age, gender, and baseline values, FBS was significantly decreased. Insulin concentration, HbA1C, HOMA-IR, and HOMA-β did not manifest significant changes. PSO increased the GLUT-4 gene expression in diabetic patients without any side effects. However, future clinical studies are needed to confirm the obtained results.

Codrituzumab, a humanized monoclonal antibody against Glypican-3 (GPC3), which is expressed in hepatocellular carcinoma (HCC), was tested in a randomized phase II trial in advanced HCC patients who had failed prior systemic therapy. Biomarker analysis was performed to identify a responder population that benefits from treatment.

Whether prostate cancer (PCa) may be preventable by dietary interventions can be assessed in randomized trials using intermediate biomarkers of cancer risk or progression. We investigated whether lycopene or green tea modify circulating insulin-like growth factor (IGF) peptides in men at increased risk of PCa. Participants (aged 50-69 years) in one centre in the UK wide PCa testing and treatment trial (ProtecT) with prostate specific antigen between 2.0 and 2.95 ng/ml or negative biopsies, were randomized to daily lycopene (n = 44 assigned 15 mg capsules/day; 44 assigned a lycopene-rich diet; 45 assigned placebo) and green tea (n = 45 assigned 600 mg/day epigallocatechin gallate; 45 assigned green tea drink; 43 assigned placebo) for 6 months. The interventions significantly elevated the primary outcomes, serum epigallocatechin gallate and lycopene at 6 months of follow-up. We report here an exploratory analysis in which serum IGF-I, IGF-II, IGF binding protein (BP)-2 and IGFBP-3 were measured at baseline and 6 months of postintervention. A total of 133 men were randomized (34% of eligible men approached) and 130 had follow-up IGF peptides (98%). In intention-to-treat analyses, there was only weak evidence that lycopene or green tea influenced some aspects of serum IGF-I, IGF-II, IGFBP-2 or IGFBP-3. In men randomized to lycopene supplements, IGFBP-2 was nonsignificantly (50.9 ng/ml; 95% confidence interval: -51.2-152.9, P = 0.3) higher in comparison to placebo, whereas in men randomized to green tea supplements, IGFBP-3 was nonsignificantly (205.2 ng/ml; 95% confidence interval: -583.3-172.9, P = 0.3) lower than with placebo. In this small, pilot randomized controlled trial, there was little evidence that lycopene or green tea interventions influenced serum levels of IGF-I, IGF-II, IGFBBP-3 and IGFBP-2. However, the effects were imprecisely estimates and some observed trends may justify larger trials.

ASN002 is an oral dual inhibitor of Janus kinase and spleen tyrosine kinase, which are involved in the pathogenesis of atopic dermatitis (AD) through their regulatory role on T helper (Th)1, Th2 and Th17/Th22 pathways.

MicroRNA are critical to the coordinated post-transcriptional regulation of gene expression, yet few studies have addressed the influence of habitual diet on microRNA expression. High protein diets impact cardiometabolic health and body composition in the elderly suggesting the possibility of a complex systems response. Therefore, high-throughput small RNA sequencing technology is applied in response to doubling the protein recommended dietary allowance (RDA) over 10 weeks in older men to examine alterations in circulating miRNAome.

This study aims to compare the differential gene expression resulting from tocotrienol-rich fraction and α-tocopherol supplementation in healthy older adults.

With respect to the role of chronic inflammation in the induction and progression of breast cancer (BC). The relationship between tumor and tumor microenvironment may be a hopeful strategy for BC therapy. According to the effect of β-D-Mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory drug (NSAID) on BC murine model and 4T1 cell line, we started to study that was a phase II, randomized, controlled clinical trial. 24 women with BC were included in this study and were followed by fixed oral doses of M2000, 500 mg two times a day (6-8 weeks). Blood samples were collected at baseline and weeks 6-8. To compare the patterns of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), C-C motif chemokine ligand 22 (CCL22) and The transforming growth factor-beta 1 (TGFβ1) gene expression and T regulatory cells (Tregs) frequency of healthy women normal controls with BC patients, a set of 10 blood samples of  women healthy volunteers was collected. The gene expression was evaluated by quantitative Real-time PCR (qRT-PCR) and the frequency of Tregs was assessed by flow cytometry. Our results showed, reduction in MMP-2 (p=0.08), MMP-9 (p=0.03), CCL22 (p=0.003) and TGFβ1 (p=0.1) gene expression and Tregs frequency (p=0.01) which play a main role in the development of chronic inflammation, angiogenesis, tumorigenesis and metastasis. Our findings demonstrated that M2000 therapy as a novel designed NSAID had valuable therapeutic effects on BC. No adverse effects were observed following the use of M2000 after 6-8 weeks.

Our previous double-blinded, placebo-controlled cross-over study indicated that a nutritional supplement named lycopene-rich tomato nutrient complex (TNC) can protect from UVA1-induced (340-400 nm) and UVA- (320-400 nm)/UVB-induced (280-320 nm) upregulation of molecular markers associated with oxidative stress, inflammation, and ageing.

Ursodeoxycholic acid (UDCA) is an intestinal bacterial metabolite with hepatoprotective effects. However, molecular mechanisms underlying its effects remain unclear.

The WSG-PRIMe Study prospectively evaluated the impact of the 70-gene signature MammaPrint® (MP) and the 80-gene molecular subtyping assay BluePrint® on clinical therapy decisions in luminal early breast cancer.

Endometriosis is an inflammatory disease; the hallmark of inflammation is over-activation of matrix metalloproteinases (MMPs). The regulatory effects of Resveratrol on MMPs were formerly depicted in other cell lines. This study aimed at investigating the effects of Resveratrol on expression of MMP-2 and -9 in endometriosis patients. This trial was carried out on endometriosis patients (n = 34) who were randomly divided into treatment (i = 17) and control (n = 17) groups. Alongside the routine protocol, the control and treatment groups took placebo and Resveratrol (400 mg), respectively, for 12-14 weeks. Endometrial tissue and fluid as well as blood sampling from both groups were done before and after the intervention. The level of mRNA and protein of both MMP-2 and -9 reduced in the endometrium of treatment group following intervention. Also, the serum and the endometrial fluid concentration of them lowered within the treatment group. Moreover, the serum and endometrial fluid levels of MMP-2 as well as MMP-9 were also diminished following the surgical removal of endometritic lesions. We showed that Resveratrol can modify the inflammation process in the endometrium of women with endometriosis at least in the level of MMP-2 and -9 expressions. The therapeutic potency of Resveratrol in endometriosis needs more clinical studies.

Lifestyle interventions, including exercise and dietary supplementation, can modify DNA methylation and exert health benefits; however, the underlying mechanisms are poorly understood. Here we investigated the impact of acute aerobic exercise and the supplementation of omega-3 polyunsaturated fatty acids (n-3 PUFA) and extra virgin olive oil (EVOO) on global and gene-specific (PPARGC1A, IL6 and TNF) DNA methylation, and DNMT mRNA expression in leukocytes of disease-free individuals. Eight trained male cyclists completed an exercise test before and after a four-week supplementation of n-3 PUFA and EVOO in a double-blind, randomised, repeated measures design. Exercise triggered global hypomethylation (Pre 79.2%; Post 78.7%; p = 0.008), alongside, hypomethylation (Pre 6.9%; Post 6.3%; p < 0.001) and increased mRNA expression of PPARGC1A (p < 0.001). Associations between PPARGC1A methylation and exercise performance were also detected. An interaction between supplement and trial was detected for a single CpG of IL6 indicating increased DNA methylation following n-3 PUFA and decreased methylation following EVOO (p = 0.038). Global and gene-specific DNA methylation associated with markers of inflammation and oxidative stress. The supplementation of EVOO reduced DNMT1 mRNA expression compared to n-3 PUFA supplementation (p = 0.048), whereas, DNMT3a (p = 0.018) and DNMT3b (p = 0.046) mRNA expression were decreased following exercise. In conclusion, we demonstrate that acute exercise and dietary supplementation of n-3 PUFAs and EVOO induce DNA methylation changes in leukocytes, potentially via the modulation of DNMT mRNA expression. Future studies are required to further elucidate the impact of lifestyle interventions on DNA methylation.

Gut appetite hormone responses may be influenced by meal macronutrients and obesity. The primary aim of this study was to examine in adolescents with obesity and of healthy weight the effect of a high-protein and a high-carbohydrate meal on postprandial gut appetite hormones. A postprandial cross-over study with adolescents 11⁻19 years old was undertaken. Participants consumed, in random order, a high 79% carbohydrate (HCHO) and a high 55% protein (HP) meal. Ghrelin, glucagon-like peptide 1 (GLP-1), peptide YY (PYY), and self-reported appetite were assessed for four hours postprandial. Total energy intake from an ad libitum lunch and remaining 24 h was assessed. Eight adolescents with obesity (OB) and 12 with healthy weight (HW) participated. Compared with HW, OB adolescents displayed a smaller ghrelin iAUC (-25,896.5 ± 7943 pg/mL/4 h vs. -60,863.5 ± 13104 pg/mL/4 h) (p = 0.008) with no effect of meal (p > 0.05). The suppression of ghrelin relative to baseline was similar between OB and HW. Ghrelin suppression was greater following the HP vs. HCHO meal (effect of meal, p = 0.018). Glucose and insulin response were greater following HCHO vs. HP, with responses more marked in OB (time × weight × meal interaction, p = 0.003 and p = 0.018, respectively). There were no effects of weight or macronutrient on GLP-1 or PYY, appetite or subsequent energy intake. The present study demonstrates that dietary protein can modulate postprandial ghrelin responses; however, this did not translate to subsequent changes in subjective appetite or energy intake.

GBR 830 is a humanized mAb against OX40, a costimulatory receptor on activated T cells. OX40 inhibition might have a therapeutic role in T cell-mediated diseases, including atopic dermatitis (AD).

Children prenatally exposed to maternal depression more often show behavioral and emotional problems compared to unexposed children, possibly through epigenetic alterations. Current evidence is largely based on animal and observational human studies. Therefore, evidence from experimental human studies is needed. In this follow-up of a small randomized controlled trial (RCT), DNA-methylation was compared between children of women who had received cognitive behavioral therapy (CBT) for antenatal depression and children of women who had received treatment as usual (TAU). Originally, 54 women were allocated to CBT or TAU. A beneficial treatment effect was found on women's mood symptoms.

Vitamin D supplementation has been widely promoted to restore 25-hydroxyvitamin D concentrations; however, experimental evidence suggests a nutrient interaction with vitamin K. We assessed the effects of 1200 IU vitamin D₃ per day versus placebo for six months on vitamin K status in a randomized, double-blind, placebo-controlled trial with participants aged 60⁻80 years with depressive symptoms and ≥1 functional limitation for a secondary analysis. Stored baseline and six-month follow-up blood samples were available for 131 participants (n = 65 placebo vs. n = 66 vitamin D supplementation). We measured dephosphorylated uncarboxylated matrix gla protein (MGP) (dp-ucMGP) concentrations-a marker of vitamin K deficiency. Mean age was 68 years, and 89 participants (68%) were women. Vitamin K antagonists were used by 16 participants and multivitamin supplements by 50 participants. No differences in change between intervention and placebo were found (-38.5 ± 389 vs. 4.5 ± 127 (pmol/L), p = 0.562). When excluding vitamin K antagonist users and multivitamin users, dp-ucMGP at follow-up was significantly higher in the vitamin D group (n = 40) compared to placebo (n = 30), with a difference of 92.8 (5.7, 180) pmol/L, adjusting for baseline dp-ucMGP and sex. In conclusion, vitamin D supplementation for six months did not affect vitamin K status; however, among participants without vitamin K antagonist or multivitamin use, vitamin D supplementation influenced dp-ucMGP concentrations.

Inflammation and oxidative stress are important factors in the development of cardiovascular disease and atherosclerosis. The findings of our previous study suggest that 12 weeks consumption of tart cherry juice lowers the levels of systolic blood pressure (BP) and low-density lipoprotein (LDL) cholesterol in older adults. The present study investigated the effects of tart cherry juice on blood biomarkers of inflammation and oxidative stress. In this randomized-controlled clinical trial, a total of 37 men and women between the ages of 65⁻80 were randomly assigned to consume 480 mL of tart cherry juice or control drink daily for 12 weeks. Several blood biomarkers of inflammation and oxidative stress were assessed at baseline and after 12 weeks intervention. After the 12 weeks intervention, tart cherry juice significantly increased the plasma levels of DNA repair activity of 8-oxoguanine glycosylase (p < 0.0001) and lowered (p = 0.03) the mean c-reactive protein (CRP) level compared to the control group. There was a significant group effect observed for plasma CRP (p = 0.03) and malondialdehyde (MDA) (p = 0.03), and a borderline significant group effect observed for plasma oxidized low-density lipoprotein (OxLDL) (p = 0.07). Within group analysis showed that the plasma levels of CRP, MDA, and OxLDL decreased numerically by 25%, 3%, and 11%, respectively after 12 weeks of tart cherry juice consumption compared with corresponding baseline values. The present study suggests that the ability of tart cherry juice to reduce systolic BP and LDL cholesterol, in part, may be due to its anti-oxidative and anti-inflammatory properties. Larger and longer follow-up studies are needed to confirm these findings.
