The prognostic role of ACSL4 in postoperative adjuvant TACE-treated HCC: implications for therapeutic response and mechanistic insights.

Background: The response of hepatocellular carcinoma (HCC) to transarterial chemoembolization (TACE) treatment and its underlying mechanisms remain elusive. This study investigates the role of enzymes involved in fatty acid activation, specifically Acyl-CoA synthetase long chain 4 (ACSL4), in HCC patients treated with postoperative adjuvant TACE (PA-TACE) and in nutrient-deprived HCC cells.

Methods: We examined the expression of ACSL4 and its family members in HCC clinical samples and cell lines.

Proteomic and lipidomic landscape of the infrapatellar fat pad and its clinical significance in knee osteoarthritis.

Osteoarthritis (OA) is a prevalent joint disease that can be exacerbated by lipid metabolism disorders. The intra-articular fat pad (IFP) has emerged as an active participant in the pathological changes of knee OA (KOA). However, the proteomic and lipidomic differences between IFP tissues from KOA and control individuals remain unclear.

Simultaneous treatment with sorafenib and glucose restriction inhibits hepatocellular carcinoma in vitro and in vivo by impairing SIAH1-mediated mitophagy.

Transarterial chemoembolization (TACE) is the first-line treatment for unresectable intermediate-stage hepatocellular carcinoma (HCC). It is of high clinical significance to explore the synergistic effect of TACE with antiangiogenic inhibitors and the molecular mechanisms involved. This study determined that glucose, but not other analyzed nutrients, offered significant protection against cell death induced by sorafenib, as indicated by glucose deprivation sensitizing cells to sorafenib-induced cell death.

Identification of Key Genes in Purine Metabolism as Prognostic Biomarker for Hepatocellular Carcinoma.

Background: Deregulated purine metabolism is critical for fast-growing tumor cells by providing nucleotide building blocks and cofactors. Importantly, purine antimetabolites belong to the earliest developed anticancer drugs and are still prescribed in clinics today. However, these antimetabolites can inhibit non-tumor cells and cause undesired side effects.

ACSL4 is a predictive biomarker of sorafenib sensitivity in hepatocellular carcinoma.

Sorafenib is the first-line treatment of advanced hepatocellular carcinoma (HCC). However, there is a lack of validated biomarkers to predict sorafenib sensitivity. In this study we investigated the role of ACSL4, a positive-activating enzyme of ferroptosis, in sorafenib-induced cell death and HCC patient outcome.

Histone deacetylases up-regulate C/EBPα expression through reduction of miR-124-3p and miR-25 in hepatocellular carcinoma.

Background: CCAAT enhancer binding protein α (C/EBPα), as an important transcription factor involved in cell proliferation, differentiation and metabolism, was up-regulated in primary hepatocellular carcinoma (HCC) and predicted poorer prognosis. In this study, we explored how histone deacetylases (HDACs) up-regulated C/EBPα in HCC.

Methods: The protein expressions of HDAC1, HDAC2 were associated with C/EBPα by immunohistochemistry staining in a HCC tissue microarray.

A pilot clinical study of apatinib plus irinotecan in patients with recurrent high-grade glioma: Clinical Trial/Experimental Study.

Background: Malignant glioma is the most common primary malignant brain tumor that displays high vascularity, making vascular endothelial growth factor receptors become promising targets. This study was conducted to evaluate the efficacy and safety of apatinib, a new potent oral small-molecule tyrosine kinase inhibitor targeted vascular endothelial growth factor receptor 2, combined with irinotecan, in patients with recurrent malignant glioma.

Methods: Ten patients with recurrent malignant glioma who were experiencing relapse after treatment of temozolomide were enrolled in this study.
