The mammalian target of rapamycin (mTOR) has been shown to play a central role in regulating cell growth and metabolism. However, little is known about the function mTOR nutrient metabolism bivalve mollusks. In this study, regulation was investigated Sinonovacula constricta. First, activation assayed after starvation refeeding. Afterwards, using an activator (MHY1485) or inhibitor (rapamycin) m...

Everolimus, an inhibitor of the mammalian target of rapamycin (mTOR), is effective in treating tumors harboring alterations in the mTOR pathway. Mechanisms of resistance to everolimus remain undefined. Resistance developed in a patient with metastatic anaplastic thyroid carcinoma after an extraordinary 18-month response. Whole-exome sequencing of pretreatment and drug-resistant tumors revealed ...

Introduction . Current chemotherapy of breast cancer has a wide range disadvantages, in particular, the development therapy-related infections and hormonal imbalance. Combination main cytostatic with glucocorticoids allows to broaden its therapeutic interval decrease total toxicity treatment. However, long-term treatment leads severe side effects via activation multiple molecular mechanisms. Th...

Mammalian target of rapamycin (mTOR) is a protein kinase that controls cell growth, proliferation, and survival. mTOR signaling is often upregulated in cancer and there is great interest in developing drugs that target this enzyme. Rapamycin and its analogs bind to a domain separate from the catalytic site to block a subset of mTOR functions. These drugs are extremely selective for mTOR and are...

Purpose: To elucidate the effect of leonurine on proliferation, invasion, migration, and angiogenetic potential breast cancer cells. Methods: Human cell line (MDA-MB-231) normal line, (SK-BR-3) were cultured. Both lines treated with 200, 400, or 800 μM cultured for 0 (control), 24, 48, 72 h. Cell counting kit-8 (CCK8) colony formation assays performed to measure viability proliferation. Invasio...

AIM AND OBJECTIVE Laryngeal carcinoma is one of the most aggressive cancers of the head and neck region. The survival rate of patients with laryngeal carcinoma is low due to its late metastases and resistance to chemotherapy and radiotherapy. It was reported that mTOR was involved in the growth and apoptosis of various cancer cells. The aim of this study was to detect the effects of mTOR inhibi...

The microbially derived antiproliferative agent rapamycin inhibits cell growth by interfering with the signaling functions of the mammalian target of rapamycin (mTOR). In this study, we demonstrate that interleukin-3 stimulation induces a wortmannin-sensitive increase in mTOR kinase activity in a myeloid progenitor cell line. The involvement of phosphoinositide 3'-kinase (PI3K) in the regulatio...

Signaling through the mammalian target of rapamycin (mTOR) controls cell size and growth as well as other functions, and it is a potential therapeutic target for graft rejection, certain cancers, and disorders characterized by inappropriate cell or tissue growth. mTOR signaling is positively regulated by hormones or growth factors and amino acids. mTOR signaling regulates the phosphorylation of...

Prostate cancer patients with localized disease are treated with curative intent. However, the disease will recur in approximately 30% of patients with a high incidence of morbidity and mortality. Prognostic biomarkers are needed to identify patients with high risk of relapse. mTOR pathway activation is reported in prostate cancer, but clinical trials testing efficacy of mTOR inhibitors were un...
