Regulation of mTOR signaling by long non-coding RNA

Publication date: Available online 18 November 2019Source: Biochimica et Biophysica Acta (BBA) - Gene Regulatory MechanismsAuthor(s): Karam AboudehenAbstractThe mechanistic target of rapamycin (mTOR) is a major signaling hub that coordinates cellular and organismal responses, such as cell growth, proliferation, apoptosis, and metabolism. Dysregulation of mTOR signaling occurs in many human diseases, and there are significant ongoing efforts to pharmacologically target this pathway. Long noncoding RNAs (lncRNA), defined by a length > 200 nucleotides and absence of a long open-reading-frame, are a class of non-protein-coding RNAs. Mutations and dysregulations of lncRNAs are directly linked to the development and progression of many diseases, including cancer, diabetes, and neurologic disorders. Recent findings reveal diverse functions for lncRNA that include transcriptional regulation, organization of nuclear domains, and regulation of proteins or RNA molecules. Despite considerable development in our understanding of lncRNA over the past decade, only a fraction of annotated lncRNAs has been examined for biological function. In addition, lncRNAs have emerged as therapeutic targets due to their ability to modulate multiple pathways, including mTOR signaling. This review will provide an up-to-date summary of lncRNAs that are involved in regulating mTOR pathway.

Abstract Human epididymis protein 4 (HE4) is an available tumor biomarker mainly for detecting ovarian cancer. However, it is unknown whether it can be a novel indicator for diagnosis of diabetic kidney disease (DKD). The aim of this study was to investigate the possibility of serum HE4 as a novel biomarker for DKD in patients with type 2 diabetes mellitus (T2DM). We enrolled 236 patients with T2DM and 82 healthy individuals. Serum HE4 was detected by ARCHITECT i2000 and compared between T2DM patients and healthy controls. The relationships between various variables and HE4 were analyzed by univariate or multivari...

However, its successful delivery remains a challenge. Up to now...

Authors: Sun L, Liu W, Zhang LJ Abstract As the key defense molecules originally identified in Drosophila, Toll-like receptor (TLR) superfamily members play a fundamental role in detecting invading pathogens or damage and initiating the innate immune system of mammalian cells. The skin, the largest organ of the human body, protects the human body by providing a critical physical and immunological active multilayered barrier against invading pathogens and environmental factors. At the first line of defense, the skin is constantly exposed to pathogen-associated molecular patterns (PAMPs) and damage-associated molecul...

The immune system is increasingly recognized as a key player in glioma pathobiology. Small case ‐control studies have found inverse associations between autoimmune diseases and glioma incidence. We performed a large case‐control study, which did not replicate these associations. However, our data indicate that inflammatory bowel disease (IBD) among patients ≤40 years are associated with an increased risk of glioma. Further studies are needed to explore the role of IBD and altered microbiota in glioma. AbstractEffectors from the immune system can modulate the course and possibly the early development of gliomas....

While at least six types of cancer have been associated with diabetes, pancreatic ductal adenocarcinoma (PDAC) and diabetes exhibit a unique bidirectional relationship. Recent reports indicate that majority of PDAC patients display hyperglycemia, and ~50% have concurrent diabetes. In turn, hyperglycemic/diabetic state in PDAC patients fosters enhanced growth and dissemination of the tumor. Heparanase enzyme (the sole mammalian endoglycosidase degrading glycosaminoglycan heparan sulfate) is tightly implicated in PDAC progression, aggressiveness, and therapy resistance. Overexpression of heparanase is a characteristic featur...

This study raises serious concerns about whether we’ve been careful enough about the safety of this chemical,” said Patricia Hunt, a professor of molecular bioscience at Washington State, and a corresponding author of the paper, in a statement. Despite how huge the difference, the results are not getting much evident pushback from other researchers in the field. “It honestly blew my mind—not because I don’t believe it, but because it appears to be true,” says Lori Hoepner, assistant professor of environmental and occupational health sciences at SUNY Downstate School of Public Health. &ld...
