Autophagy is a cellular housekeeping process that incorporates lysosomal-degradation to maintain cell survival and energy sources. In recent decades, the role of autophagy has implicated in the initiation and development of many diseases that affect humanity. Among these diseases are autoimmune diseases and neurodegenerative diseases, which connected with the lacking autophagy. Other diseases are connected with the increasing levels of autophagy such as cancers and infectious diseases. Therefore, controlling autophagy with sufficient regulators could represent an effective strategy to overcome such diseases. Interestingly, targeting autophagy can also provide a sufficient method to combat the current epidemic caused by the ongoing coronavirus. In this review, we aim to highlight the physiological function of the autophagic process to understand the circumstances surrounding its role in the cellular immunity associated with the development of human diseases.

Background: Coronary artery disease (CAD) has become a dominant economic and health burden worldwide, and the role of autophagy in CAD requires further clarification. In this study, we comprehensively revealed the association between autophagy flux and CAD from multiple hierarchies. We explored autophagy-associated long noncoding RNA (lncRNA) and the mechanisms underlying oxidative stress-induced human coronary artery endothelial cells (HCAECs) injury.

Background/aim: Salmonella typhimurium A1-R (A1-R) targets and inhibits a wide range of cancer types without continuously infecting healthy tissue. Chloroquine, an antimalarial drug, induces apoptosis and inhibits autophagy in cancer cells. The aim of the present study was to determine the synergy of A1-R plus chloroquine on HT1080 human fibrosarcoma cells in vitro and in a nude-mouse model.

The disease burden of renal cell carcinoma (RCC) has decreased in recent years with advances in treatment, but its pathogeny still remains elusive. We aim to study the role of HOXA3/USP15/SQSTM1 axis on autophagy and M2-type macrophage polarization in RCC. In this study, cell apoptosis and proliferation were assessed by flow cytometry and CCK-8.
