The long non-coding RNA HOX transcript antisense RNA (HOTAIR) plays a key role in the progression of various carcinomas. However, whether or not HOTAIR influences glucose metabolism and the specific underlying mechanism in hepatocellular carcinoma (HCC) cells remain unclear. In the present study, we found markedly increased HOTAIR expression in 84 HCC tissues and demonstrated that HOTAIR overexpression promoted cell proliferation using Cell Counting Kit-8. The effect on glucose metabolism regulated by HOTAIR in HCC cells was determined by detecting lactate and glucose levels: HOTAIR promoted glycolysis by upregulating glucose transporter isoform 1 (GLUT1) and activating mammalian target of rapamycin (mTOR) signaling, whereas knockdown of HOTAIR suppressed this effect. Our research reveals a novel relationship between HOTAIR and glucose metabolism in HCC cells, and it may be a therapeutic target for diagnosing and treating HCC.

Background: Hypertension (HTN) is a global public health concern and a major risk factor for cardiovascular disease (CVD) and mortality. Insulin resistance (IR) plays a crucial role in HTN-related metabolic dysfunction, but its assessment remains challenging. The triglyceride-glucose (TyG) index and its derivatives (TyG-BMI, TyG-WC, and TyG-WHtR) have emerged as reliable IR markers.

Background: Olaparib is a relatively new poly(ADP-ribose) polymerase inhibitor (PARPi) administered to ovarian cancer (OC) patients with a complete or partial response to first-line chemotherapy. One of the metabolic side effects of olaparib is the disruption of glucose homeostasis, often resulting in hyperglycemia The study was a retrospective analysis of olaparib-induced hyperglycemia in OC patients with initial normoglycemia following the first, second, and third month of olaparib treatment METHODS: The study involved 32 OC patients, classified into three groups according to their Body Mass Index (BMI): normal BMI (BMI 18.5-24.

It is challenging to study metabolic interaction between the different cell types in a tissue with the techniques that are currently available. Here we describe a multimodal imaging pipeline that allows cell type identification and nanoscale tracing of stable isotope-labeled compounds.

Levilactobacillus brevis YT108, identified for its ability to metabolize prebiotic xylo-oligosaccharides (XOS), emerges as a candidate for probiotic use in synbiotic food formulations. This study aimed to investigate the metabolic and genomic traits associated with XOS metabolism in YT108 and to assess its probiotic attributes through whole genome sequencing and in vitro assays. Strain YT108 exhibited robust growth kinetics on XOS as the sole carbon source, with a growth profile comparable to that on glucose, achieving a pH reduction to 4.
