background: autophagy as a cellular pathway facilitates several immune responses against infection. it also eliminates invading pathogens through transferring content between the cytosol and the lysosomal vesicles and contributes to the cross-presentation of exogenous antigens to t lymphocytes via mhc class i pathway. autophagy induction is one of the main targets for new drugs and future vacci...

Objective(s): To investigate the role of autophagy in advanced glycation end products (AGEs)-induced proliferation and migration in rat vascular smooth muscle cells (VSMCs).Materials and Methods: After culture, VSMCs were treated with 0, 1, 10, and 100 μg/ml concentrations of AGEs. Autophagy specific protein light chain 3 (LC3)-I/II was determined by western blotting, autophagosomes were observ...

Breast cancer (BC) is a potentially life-threatening malignant tumor that still causes high mortality among women. One of the mechanisms through which cancer development could be controlled is autophagy. This process exerts different effects during the stages of cancer initiation and progression due to the occurring superimposition of signaling pathways of autophagy and carcinogenesis. Chronic ...

conclusions these results indicated a potential explanation for reactivation of hbv infection when patients with hepatitis receive rapamycin. results in hepg2.2.15 cells, hbv dna and hbsag increased when host cells were treated with rapamycin and the effect was reversed by autophagy inhibitor, 3-methyladenine (3-ma). materials and methods hepg2.2.15 cells were treated with rapamycin to induce a...

Autophagy is a highly regulated catabolic process that involves lysosomal degradation of proteins and organelles, mostly mitochondria, for the maintenance of cellular homeostasis and reduction of metabolic stress. Problems in the execution of this process are linked to different pathological conditions, such as neurodegeneration, aging, and cancer. Many of the proteins that regulate autophagy a...

understanding the mechanism of tumor resistance is critical for cancer therapy. in this study, we investigated the effect of carcinoembryonic antigen (cea) overexpression on uv-and 5-fluorouracil (5-fu)-induced apoptosis and autophagy in colorectal cancer cells. we used histone deacetylase (hdac) inhibitor, nab and dna demethylating agent, 5- azacytidine (5-aza) to induce cea expression in ht29...

BACKGROUND Autophagy is a basic cellular homeostatic process important to cell fate decisions under conditions of stress. Dysregulation of autophagy impacts numerous human diseases including cancer and chronic obstructive lung disease. This study investigates the role of autophagy in idiopathic pulmonary fibrosis. METHODS Human lung tissues from patients with IPF were analyzed for autophagy m...

As current classical Hodgkin lymphoma (cHL) treatment strategies have pronounced side-effects, specific inhibition of signaling pathways may offer novel strategies in cHL therapy. Basal autophagy, a regulated catabolic pathway to degrade cell's own components, is in cancer linked with both, tumor suppression or promotion. The finding that basal autophagy enhances tumor cell survival would thus ...

A utophagy, the process of “selfeating” within cells, has been controversial in cancer since it was first linked to the disease in 1999. Because autophagy can either suppress or promote tumors, depending on the context, the field has been marked by both confusion and unwillingness by drug companies to get involved in therapies. But that’s changed. A consensus is emerging that it’s the tumor pro...
