Abstract Metabolic reprogramming and epigenetic modifications are hallmarks of cancer cells. In cells, metabolic pathway activity varies during tumorigenesis progression, indicating regulated plasticity. changes often closely related to changes, such as alterations in the expression or epigenetically modified enzymes, which may exert a direct an indirect influence on cellular metabolism. Therefore, exploring mechanisms underlying regulating tumor cell metabolism is important for further understanding pathogenesis. Here, we mainly focus latest studies regulations, including glucose, lipid amino acid context, then emphasize modifications. Specifically, discuss role played by DNA methylation, chromatin remodeling, noncoding RNAs histone lactylation growth progression. Finally, summarize prospects potential therapeutic strategies based

Hepatocellular carcinoma (HCC) is one of the most common and deadly cancers worldwide. It usually diagnosed in an advanced stage characterized by a high intrinsic drug resistance, leading to limited chemotherapeutic efficacy relapse after treatment. There therefore vast need for understanding underlying mechanisms that contribute resistance developing therapeutic strategies would overcome this. The rapid proliferation tumor cells, combination with highly inflammatory microenvironment, causes chronic increase protein synthesis different hepatic cell populations. This leads intensified demand folding, which inevitably accumulation misfolded or unfolded proteins lumen endoplasmic reticulum (ER). process called ER stress triggers response (UPR) order restore or—in case severe prolonged stress—to induce death. Interestingly, three arms signaling pathways have been shown drive chemoresistance several tumors could form promising target. review provides overview how activation UPR contributes HCC.

Abstract Breast cancer is significantly influenced by endoplasmic reticulum (ER) stress, impacting both its initiation and progression. When cells experience an accumulation of misfolded or unfolded proteins, they activate the protein response (UPR) to restore cellular balance. In breast cancer, UPR frequently triggered due challenging conditions within tumors. The has a dual impact on cancer. On one hand, it can contribute tumor growth enhancing cell survival resistance programmed death in unfavorable environments. other prolonged severe ER stress trigger mechanisms, limiting Furthermore, been linked regulation non-coding RNAs (ncRNAs) cells. These ncRNAs, including microRNAs (miRNAs) long (lncRNAs), play essential roles development influencing gene expression processes. An improved understanding how ncRNAs interact potentially lead new treatment approaches. Modifying specific involved might interfere with induce death. Additionally, focusing UPR-associated proteins that could offer novel therapeutic possibilities.

Background: Tocotrienol, a type of vitamin E, is well known for its anti-cancer and other biological activities. This systematic review aims to summarize the involvement endoplasmic reticulum stress (ERS) subsequent unfolded protein response (UPR) as underlying molecular mechanisms anticancer properties tocotrienol. Method: A comprehensive literature search was performed in March 2023 using PubMed, Scopus, Web Science, EMBASE databases. In vitro, vivo, human studies were considered. Result: total 840 articles retrieved during initial search, 11 that fit selection criteria included qualitative analysis. The current mechanistic findings are based solely on vitro studies. Tocotrienol induces cancer cell growth arrest, autophagy, death primarily through apoptosis but also paraptosis-like death. Tocotrienol-rich fractions, including α-, γ- δ-tocotrienols, induce ERS, evidenced by upregulation UPR markers and/or ERS-related markers. Early calcium ion release, increased ceramide level, proteasomal inhibition, microRNA-190b suggested be essential modulating tocotrienol-mediated ERS/UPR transduction. Nevertheless, upstream mechanism tocotrienol-induced ERS largely unknown. Conclusion: effects. Further investigation needed elucidate ERS.

Although our current knowledge of the molecular crosstalk between ER stress, unfolded protein response (UPR), and lipid homeostasis remains limited, there is increasing evidence that dysregulation either or profoundly affects other. Most research regarding UPR signaling in human diseases has focused on causes consequences disrupted folding. The itself consists very complex pathways function to not only maintain homeostasis, but just as importantly, modulate biogenesis allow adjust promote cell survival. Lipid known activate many aspects UPR, complexity this a major barrier. disequilibrium lipotoxicity are be important contributors numerous pathologies, including insulin resistance, liver disease, cardiovascular diseases, neurodegenerative cancer. Despite their medical significance continuous research, however, mechanisms synthesis during stress conditions, impact fate decisions, remain poorly understood.

Efficient brain function requires as much 20% of the total oxygen intake to support normal neuronal cell function. This level usage, however, leads generation free radicals, and thus can lead oxidative stress potentially age-related cognitive decay even neurodegenerative diseases. The regulation this system a complex monitoring network maintain proper homeostasis. Furthermore, high content mitochondria in has elevated glucose demands, redox balance. Maintaining is mediated by adaptive response pathways that permit cells survive minimize cellular damage. These rely on endoplasmic reticulum (ER) activation unfolded protein (UPR), pathway responsible for ER survival. Interestingly, UPR two opposing signaling pathways, one promotes survival induces apoptosis.

The endoplasmic reticulum (ER) is crucial for protein quality control, and disruptions in its function can lead to various diseases. ER stress triggers an adaptive response called the unfolded (UPR), which either restore cellular homeostasis or induce cell death. Melatonin, a safe multifunctional compound, shows promise controlling could be valuable therapeutic agent managing UPR. By regulating mitochondrial functions, melatonin helps maintain via reduction of oxidative stress, inflammation, apoptosis. Melatonin directly indirectly interfere with ER-associated sensors downstream targets UPR, impacting death, autophagy, molecular repair, among others. Crucially, this review explores mechanistic role on diseases including liver damage, neurodegeneration, reproductive disorders, pulmonary disease, cardiomyopathy, insulin resistance, renal dysfunction, cancer. Interestingly, while it alleviates burden most pathological contexts, paradoxically stimulate cancer cells, highlighting intricate involvement homeostasis. With numerous successful studies using vivo vitro models, continuation clinical trials imperative fully explore melatonin's potential these conditions.
