Hepatocellular carcinoma (HCC) is the most common lethal form of liver cancer. Apart from surgical removal and transplantation, other treatments have not yet been well established for patients with HCC. In this study, we found that carboxylesterase 1 (CES1) expressed at various levels in We further revealed blockage CES1 by pharmacological genetical approaches leads to altered lipid profiles are directly linked impaired mitochondrial function. Mechanistically, lipidomic analyses indicated signaling molecules, including polyunsaturated fatty acids (PUFAs), which activate PPARα/γ, were dramatically reduced upon inhibition. As a result, expression SCD, PPARα/γ target gene involved tumor progression chemoresistance, was significantly downregulated. Clinical analysis demonstrated strong correlation between protein SCD Interference targeting CES1-PPARα/γ-SCD axis sensitized HCC cells cisplatin treatment. growth xenograft tumors NU/J mice potently slowed coadministration Our results, thus, suggest promising therapeutic

Abstract Lipid metabolic reprogramming is an emerging hallmark of cancer. In order to sustain uncontrolled proliferation and survive in unfavorable environments that lack oxygen nutrients, tumor cells undergo transformations exploit various ways acquiring lipid increasing oxidation. addition, stromal immune the microenvironment also reprogramming, which further affects functional phenotypes responses. Given metabolism plays a critical role supporting cancer progression remodeling microenvironment, targeting pathway could provide novel approach treatment. This review seeks to: (1) clarify overall landscape mechanisms cancer, (2) summarize landscapes within their roles progression, (3) potential therapeutic targets for metabolism, highlight combining such approaches with other anti-tumor therapies new opportunities patients.

Abstract Objectives Chondrocyte ferroptosis contributes to osteoarthritis (OA) progression, and D‐mannose shows therapeutic value in many inflammatory conditions. Here, we investigated whether interferes chondrocyte ferroptotic cell death during osteoarthritic cartilage degeneration. Materials methods In vivo anterior cruciate ligament transection (ACLT)‐induced OA mouse model an vitro study of chondrocytes microenvironment induced by interleukin‐1β (IL‐1β) exposure were employed. Combined with Epas1 gene gain‐ loss‐of‐function, histology, immunofluorescence, quantitative RT‐PCR, Western blot, viability flow cytometry experiments performed evaluate the chondroprotective effects progression role hypoxia‐inducible factor 2 alpha (HIF‐2 α) D‐mannose‐induced resistance chondrocytes. Results exerted a effect attenuating sensitivity alleviated progression. HIF‐2α was identified as central mediator Furthermore, overexpression Ad‐ intra‐articular injection abolished eliminated suppressor. Conclusions alleviates suppressing HIF‐2α‐mediated ferroptosis, indicating be potential strategy for ferroptosis‐related diseases.

Ferroptosis, a programmed cell death, has been identified and associated with cancer various other diseases. Ferroptosis is defined as reactive oxygen species (ROS)-dependent death related to iron accumulation lipid peroxidation, which different from apoptosis, necrosis, autophagy, forms of death. However, accumulating evidence revealed link between autophagy ferroptosis at the molecular level suggested that involved in regulating iron-dependent peroxidation ROS during ferroptosis. Understanding roles pathophysiological processes may provide effective strategies for treatment ferroptosis-related In this review, we summarize current knowledge regarding regulatory mechanisms underlying ferroptosis, including metabolism, its association pathway. addition, discuss contribution elucidate role enhancer ROS-dependent

Abstract Lipid metabolism is a complex biochemical process that participates in the regulation of cell survival and death. Ferroptosis form iron‐dependent regulated death driven by abnormal lipid metabolism, leading to peroxidation subsequent plasma membrane rupture. A variety antioxidant systems repair pathways can diminish oxidative damage, enabling growth response ferroptotic signals. Such impairment ferroptosis machinery implicated various pathological conditions diseases, especially cancer tissue damage. It discussed here how pathways, including synthesis, degradation, storage, transformation, utilization, modulate sensitivity or tolerance different models, cancer.
