Fangchinoline inhibits cell proliferation via Akt/GSK-3beta/ cyclin D1 signaling and induces apoptosis in MDA-MB-231 breast cancer cells.

Fangchinoline (Fan) inhibits cell proliferation and induces apoptosis in several cancer cell lines. The effects of Fan on cell growth and proliferation in breast cancer cells remain to be elucidated. Here, we show that Fan inhibited cell proliferation in the MDA-MB-231 breast cancer cell line through suppression of the AKT/Gsk- 3beta/cyclin D1 signaling pathway.

MCPH1 Protein Expression in Normal and Neoplastic Lung Tissues.

Lung cancer is the most common cause of cancer-related death in the world. The main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC), the latter including squamous cell carcinoma (SCC), adenocarcinoma and large cell carcinoma. NSCLCs account for about 80% of all lung cancer cases.

RNAi-mediated silencing of the Bmi-1 gene causes growth inhibition and enhances doxorubicin-induced apoptosis in MCF-7 cells.

The oncogene Bmi-1 is a member of the Polycomb group gene family. Its expression is found to be greatly increased in a number of malignant tumors including breast cancer. This could suggest Bmi-1 as a potent therapeutic target.

[HPV caused pathological changes in genital system of mice].

The recombined adenovirus DNA was transfected into 293 cells for packing and amplification of replication-deficient Ad-CMV-E6/E7, Ad-K14 -E6/E7 virus was purified by CsCl density gradient centrifugation , recombined adenovirus Ad-CMV-E6/E7, Ad-K14 -E6/E7 were used as experimental group, while pAd-CMV and pAdtrack-K14 were used as control group. Four of them were injected through one main vein of nude mice tail respectively. These mice were then treated with 0.

Identification and characterization of a splice variant of the catalytic domain of mouse NTE-related esterase.

Patatin-domain containing proteins constitute a large family of enzymes including known lipases that hydrolyze triglycerides, diglycerides, and phospholipids, some of which still remain to be characterized. One of those is NTE-related esterase (NRE), which exhibits sequence and domain homology to neuropathy target esterase (NTE). A splice variant of the catalytic domain of mouse NRE (mNRECV) was identified in multiple adult tissues, including brain, kidney, liver and testis.

[Rapid construction of full-length MnSOD cDNA of chickens by one-step 3'RACE].

RACE (rapid amplification of cDNA ends) is a popular technique to rapidly obtain the full-length cDNA. After obtaining the 3' cDNA and 5' cDNA fragments with a overlapped region by 3' RACE and 5' RACE, the full-length cDNA could be generated by end-to-end PCR or subcloning. In this study, 3' RACE combined with touch-down PCR was successfully used for the rapid construction of full-length MnSOD cDNA of chickens.
