Cancer cells are frequently confronted with metabolic stress in tumor microenvironments due to their rapid growth and limited nutrient supply. Metabolic induces cell death through ROS-induced apoptosis. However, cancer can adapt it by altering the pathways. AMPK AKT two primary effectors response stress: acts as an energy-sensing factor which rewires metabolism maintains redox balance. broadly promotes energy production abundance milieu, but role of under is dispute. Recent studies show that display antagonistic roles stress. stress-induced ROS signaling lies hub between reprogramming homeostasis. Here, we highlight cross-talk regulation on elimination, summarizes mechanism adaptability suggests potential options for therapeutics.

Adenosine monophosphate-activated protein kinase (AMPK) is a conserved sensor of intracellular energy activated in response to low nutrient availability and environmental stress. In screen for substrates AMPK, we identified ULK1 ULK2, mammalian orthologs the yeast Atg1, which required autophagy. Genetic analysis AMPK or liver Caenorhabditis elegans revealed requirement these kinases mammals, loss resulted aberrant accumulation autophagy adaptor p62 defective mitophagy. Reconstitution ULK1-deficient cells with mutant that cannot be phosphorylated by such phosphorylation mitochondrial homeostasis cell survival during starvation. These findings uncover biochemical mechanism coupling status survival.

Autophagy is a process of self-cannibalization. Cells capture their own cytoplasm and organelles consume them in lysosomes. The resulting breakdown products are inputs to cellular metabolism, through which they used generate energy build new proteins membranes. preserves the health cells tissues by replacing outdated damaged components with fresh ones. In starvation, it provides an internal source nutrients for generation and, thus, survival. A powerful promoter metabolic homeostasis at both whole-animal level, autophagy prevents degenerative diseases. It does have downside, however--cancer exploit survive nutrient-poor tumors.

Abstract KRAS is the most common oncogenic driver in lung adenocarcinoma (LUAC). We previously reported that STK11/LKB1 (KL) or TP53 (KP) comutations define distinct subgroups of KRAS-mutant LUAC. Here, we examine efficacy PD-1 inhibitors these subgroups. Objective response rates to blockade differed significantly among KL (7.4%), KP (35.7%), and K-only (28.6%) (P < 0.001) Stand Up To Cancer (SU2C) cohort (174 patients) with LUAC patients treated nivolumab CheckMate-057 phase III trial (0% vs. 57.1% 18.2%; P = 0.047).

Antineoplastic chemotherapies are particularly efficient when they elicit immunogenic cell death, thus provoking an anticancer immune response. Here we demonstrate that autophagy, which is often disabled in cancer, dispensable for chemotherapy-induced death but required its immunogenicity. In response to chemotherapy, autophagy-competent, not autophagy-deficient, cancers attracted dendritic cells and T lymphocytes into the tumor bed. Suppression of autophagy inhibited release adenosine triphosphate (ATP) from dying cells. Conversely, inhibition extracellular ATP-degrading enzymes increased pericellular ATP autophagy-deficient tumors, reestablished recruitment cells, restored chemotherapeutic responses only immunocompetent hosts. Thus, essential concentrations improve efficacy antineoplastic disabled.

Lymphocytes face major metabolic challenges upon activation. They must meet the bioenergetic and biosynthetic demands of increased cell proliferation also adapt to changing environmental conditions, in which nutrients oxygen may be limiting. An emerging theme immunology is that reprogramming lymphocyte activation are intricately linked. However, why T cells adopt specific programs impact these have on function and, ultimately, immunological outcome remain unclear. Research tumor metabolism has provided valuable insight into pathways important for influence metabolites themselves signal transduction epigenetic programming. In this Review, we highlight concepts regarding proliferating discuss their potential fate function.
