Human endogenous retroviruses (HERVs) were formed via ancient integration of exogenous retroviruses into the human genome and are considered to be viral "fossils". The human genome is embedded with a considerable amount of HERVs, witnessing the long-term evolutionary history of the viruses and the host. Most HERVs have lost coding capability during selection but still function in terms of HERV-mediated regulation of host gene expression. In this review, we summarize the roles of HERV activation in response to viral infections and diseases, and emphasize the potential use of HERVs as biomedicine markers in the early diagnosis of diseases such as cancer, which provides a new perspective for the clinical application of HERVs.

Background: High levels of catecholamines are cardiotoxic and associated with stress-induced cardiomyopathies. Septic patients are routinely exposed to endogenously released and exogenously administered catecholamines, which may alter cardiac function and perfusion causing ischemia. Early during human septic shock, left ventricular ejection fraction (LVEF) decreases but normalizes in survivors over 7-10 days.

MORs are widely expressed in the central nervous system (CNS), peripheral organs, and the immune system. They mediate pain and reward and have been implicated in the pathophysiology of opioid, cocaine, and other substance use disorders.

The Takeda G protein-coupled receptor 5 (TGR5), also known as GPBAR1 (G protein-coupled bile acid receptor), is a membrane-type bile acid receptor that regulates blood glucose levels and energy expenditure. These essential functions make TGR5 a promising target for the treatment of type 2 diabetes and metabolic disorders. Currently, most research on developing TGR5 agonists focuses on modifying the structure of bile acids, which are the endogenous ligands of TGR5.

Direct cardiac reprogramming or transdifferentiation is a relatively new and promising area in regenerative therapy, cardiovascular disease modeling, and drug discovery. Effective reprogramming of fibroblasts is limited by their plasticity, that is, their ability to reprogram, and depends on solving several levels of tasks: inducing cardiomyocyte-like cells and obtaining functionally and metabolically mature cardiomyocytes. Currently, in addition to the use of more classical approaches such as overexpression of exogenous transcription factors, activation of endogenous cardiac transcription factors via controlled nucleases, such as CRISPR, represents another interesting way to obtain cardiomyocytes.

SH2B1β is a multifunctional scaffold protein that modulates cytoskeletal processes such as cellular motility and neurite outgrowth. To identify novel SH2B1β-interacting proteins involved in these processes, a yeast two-hybrid assay was performed. The C-terminal 159 residues of the cytoskeleton structural protein, βIIΣ1-spectrin, interacted with the N-terminal 260 residues of SH2B1β, a region implicated in SH2B1β enhancement of cell motility and localization at the plasma membrane.
