To investigate vincristine-induced dopaminergic neurons toxicity and mechanism, and explore the molecular target to reduce the toxicity, zebrafish was chosen as a model animal, based on RT-PCR, Western blotting, whole mount in situ immunofluorescence and other technical means. The results showed that the transcription levels of tyrosine hydroxylase gene and dopamine transporter protein gene were inhibited. Furthermore, the number of dopaminergic neurons was decreased by vincristine. Autophagy was suppressed and beclin1 gene expression was inhibited in a dose-dependent manner by vincristine in larval zebrafish. Up-regulated beclin1 partly reduced vincristine-induced neurotoxicity, and down-regulated beclin1 increased toxicity. Beclin1 plays an important role in vincristine-induced dopaminergic neurons toxicity.

The aim of this study was to determine the activity region of Oct4 (octamer-binding transcription factor 4) promoter in Xuhuai goat, and to investigate the effect of TSA (trichostatin A) and VPA(valproicacid) on Oct4 promoter activity. Specific PCR primers of Oct4 promoter including different lengths of fragments were designed by Primer 5.0, then were amplified and cloned into PGL3-Bacic luciferase reporter vector. All the reconstruction vectors were transfected into gEF, P19 and COS7 cells, respectively. After TSA and VPA treatment, the activity of dual-luciferase reporter gene in these three transfected cells was detected. In addition, the CMV promoter of pEGFP-N1 was replaced by the -1516─+30 bp fragment of Oct4 promoter, GFP fluorescence was used to detect the activity of Oct4 promoter. The results indicated that different fragments of Oct4 promoter showed different degrees of activity in gEF, P19 and COS7 cells, and the maximal activity region of Oct4 promoter was -1516─+30 bp, the basal activity region was -238─+30 bp. Positive regulatory domains existed in the region of -1516─-946 bp and -615─-96 bp, while negative regulatory domains existed in the region of -1936─-1516 bp and -946─-615 bp. The optimum induction concentration to enhance the activity of Oct4 promoter was 1 μmol/L of TSA and 4 mmol/L of VPA. The GFP expression can be started by the fragment of -1516─+30 bp. This study provides an experimental basis for revealing the mechanism of expression and regulation of Oct4 in goat.

Chemotherapy drug resistance is the primary causes of death in patients with pulmonary carcinoma which make tumor recurrence or metastasis. β-tubulin is the main cell targets of anti-microtubule drug.
