Using GC data from TCGA and GEO, LSMRGs from Genecard were analyzed. Unsupervised clustering defined LSMRG-based subtypes. Differentially expressed LSMRGs were identified by intersecting tumor-normal DEGs. A prognostic risk-score model was built via univariate Cox, LASSO, and multivariate Cox analyses, with model genes validated by qRT-PCR in cell lines. Comprehensive transcriptomic analyses included nomogram development, gene enrichment, immune infiltration, somatic mutations, and drug sensitivity. LSMRG-based clustering identified two patient subtypes with distinct survival and immunotherapy responses. From 83 differentially expressed LSMRGs, a 6-gene prognostic risk-score model was constructed, validated as an independent prognostic factor. Model gene expression was confirmed via qRT-PCR. The risk score accurately predicted 1-, 3-, and 5-year survival. High- and low-risk groups exhibited differential enrichment in pathways including neuroactive ligand-receptor interaction and hormone signaling. The high-risk group had a higher mutation burden, lower immune infiltration, and distinct drug sensitivity profiles compared to the low-risk group. This study delineates the expression landscape of LSMRGs in GC and clarifies their associations with molecular subtypes, prognosis, and immune regulation. The findings provide novel prognostic biomarkers and a molecular basis for targeting lipid-soluble signaling pathways in GC therapy.</p>","PeriodicalId":18086,"journal":{"name":"Lipids","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147856516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functional enrichment via ShinyGO revealed that the 145 common genes converge predominantly on inflammatory, metabolic, and mitochondrial pathways. Tumor necrosis factor (TNF) emerged as a principal regulatory node, exerting influence through Mitogen-Activated Protein Kinase (MAPK)-mediated apoptotic and stress-response cascades that plausibly contribute to mitochondrial dysfunction, oxidative stress, impaired energy metabolism, and myocellular injury in the context of CoQ10 depletion. The constructed pathway-based interaction network illustrates how suppression of the mevalonate pathway by statins disrupts CoQ10 biosynthesis, sensitizing muscle tissue to cytokine-driven inflammatory signaling and amplifying apoptotic susceptibility. Collectively, the findings highlight the TNF-MAPK axis as a mechanistic core of SAMS pathophysiology and underscore the interconnected roles of immune activation, lipid metabolic imbalance, and mitochondrial impairment.

Besides, there was competition between the catabolism of cholesterol to bile acids or CS, as evidenced by the opposite trend between the TBA to cholesterol ratio and the CS to TBA ratio. Moreover, for the first time, it has been discovered that CS is enriched in lipid droplets, which further substantiates the close association between CS and lipid metabolism.

This study at Xuzhou Central Hospital from January 2021 to December 2023 included 151 patients divided into a statin group (n = 73) and a PCSK9 inhibitor (PCSK9i) group (n = 78). It evaluated lipid profiles, inflammatory markers, neurological function, and clinical outcomes over a 180-day follow-up period, with additional analysis stratified by CYP2C19 genotype. The PCSK9i group demonstrated significant improvements in lipid parameters compared to the statin group, including greater reductions in low-density lipoprotein cholesterol (LDL-C) (p = 0.008), total cholesterol (TC) (p < 0.001), and triacylglycerols (TAG) (p = 0.041), along with apolipoprotein A1 (ApoA1) and apolipoprotein B (ApoB) (both p < 0.001).

Post-treatment modified Rankin Scale (mRS) scores were significantly lower in rapid metabolizers compared to slow metabolizers (p = 0.018), though clinical events occurred infrequently in both subgroups.

Indeed, patients with HA-PCOS were found to have the highest incidence of dyslipidemia among patients with the other three subtypes of PCOS. In the present study, we identified genes involved in lipid-associated processes (namely, lipid biosynthetic process, lipid catabolic process, hyperlipidemia, hypolipidemia and lipid homeostasis) whose expression are changed in granulosa cells from HA-PCOS patients compared to those from non-PCOS women, in order to identify molecular factors contributing to the highest risk of dyslipidemia incidence observed in patients with hyperandrogenic PCOS.
