The initial presentation of non-alcoholic steatohepatitis (NASH) is hepatic steatosis. dysfunction lipid metabolism within hepatocytes caused by genetic factors, diet, and insulin resistance causes accumulation. Lipotoxicity, oxidative stress, mitochondrial dysfunction, endoplasmic reticulum stress would further contribute to hepatocyte injury death, leading inflammation immune in the liver. During healing process, accumulation an excessive amount fibrosis might occur while healing. development NASH liver fibrosis, gut-liver axis, adipose-liver renin-angiotensin system (RAS) may be dysregulated impaired.

Abstract A common feature of cancer cells is their ability to rewire metabolism sustain the production ATP and macromolecules needed for cell growth, division survival. In particular, importance altered fatty acid in has received renewed interest as, aside principal role as structural components membrane matrix, they are important secondary messengers, can also serve fuel sources energy production. this review, we will examine mechanisms through which with a focus on four main areas research. (1) The de novo synthesis exogenous uptake cellular pool acids. (2) molecular heterogeneity oncogenic signal transduction pathways, such PI3K–AKT–mTOR signalling, regulate metabolism. (3) acids essential mediators progression metastasis, remodelling tumour microenvironment. (4) Therapeutic strategies considerations successfully targeting cancer. Further research focusing complex interplay between signalling dysregulated holds great promise uncover novel metabolic vulnerabilities improve efficacy targeted therapies.

Abstract Mammalian target of rapamycin (mTOR) regulates cell proliferation, autophagy, and apoptosis by participating in multiple signaling pathways the body. Studies have shown that mTOR pathway is also associated with cancer, arthritis, insulin resistance, osteoporosis, other diseases. The pathway, which often activated tumors, not only gene transcription protein synthesis to regulate proliferation immune differentiation but plays an important role tumor metabolism. Therefore, a hot anti-tumor therapy research. In recent years, variety newly discovered inhibitors entered clinical studies, drugs been proven high activity combination inhibitors. purpose this review introduce on apoptosis, growth, metabolism cells, research progress field.

Cells metabolize nutrients for biosynthetic and bioenergetic needs to fuel growth proliferation. The uptake of from the environment their intracellular metabolism is a highly controlled process that involves cross talk between signaling metabolic pathways. Despite constant fluctuations in nutrient availability environmental signals, normal cells restore homeostasis maintain cellular functions prevent disease. A central molecule integrates with mechanistic target rapamycin (mTOR). mTOR protein kinase responds levels signals. forms two complexes, mTORC1, which sensitive rapamycin, mTORC2, not directly inhibited by this drug. Rapamycin has facilitated discovery various mTORC1 metabolism. Genetic models disrupt either or mTORC2 have expanded our knowledge cellular, tissue, as well systemic Nevertheless, regulation particularly metabolism, lagged behind. Since an important cancer, aging, other metabolism-related pathologies, understanding distinct overlapping complexes vital development more effective therapeutic strategies. This review discusses key discoveries recent findings on complexes. We highlight cancer but also discuss examples mTOR-mediated reprogramming occurring stem immune cells, type 2 diabetes/obesity, neurodegenerative disorders, aging.

Lipid droplets (also known as lipid bodies) are lipid-rich, cytoplasmic organelles that play important roles in cell signaling, metabolism, membrane trafficking, and the production of inflammatory mediators. droplet biogenesis is a regulated process, accumulation these within leukocytes, epithelial cells, hepatocytes, other nonadipocyte cells frequently observed phenotype several physiologic or pathogenic situations thoroughly described during conditions. Moreover, recent years, studies have an increase intracellular different neoplastic processes, although it not clear whether directly involved establishment types malignancies.

Hepatocellular carcinoma (HCC) is an aggressive human cancer with increasing incidence worldwide. Multiple efforts have been made to explore pharmaceutical therapies treat HCC, such as targeted tyrosine kinase inhibitors, immune based and combination of chemotherapy. However, limitations exist in current strategies including chemoresistance for instance. Tumor initiation progression driven by reprogramming metabolism, particular during HCC development. Recently, metabolic associated fatty liver disease (MAFLD), a reappraisal new nomenclature non-alcoholic (NAFLD), indicates growing appreciation metabolism the pathogenesis disease, thereby suggesting targeting abnormal treatment. In this review, we introduce directions highlighting targets glucose, acid, amino acid glutamine which are suitable intervention. We also summarize discuss agents studies deregulated Furthermore, opportunities challenges discovery development therapy discussed.
