Emerging research studies highlight MALT1 inhibitors as promising therapeutic agents for B-cell malignancies, with several candidates demonstrating preclinical and clinical efficacy. Notably, agents such as safimaltib (JNJ-67856633) have shown manageable safety profiles and preliminary antitumor activity in early-phase trials for relapsed/refractory B-cell malignancies. However, MALT1-targeted therapy poses a dual challenge: although inhibiting oncogenic signaling and tumor cell proliferation, it also disrupts immunosuppressive Treg function, risking autoimmune toxicity by compromising the tumor microenvironment.

Glutamine serves as a key alternative resource for cancer cells, yet the metabolic mechanisms involving its transporters in non-small cell lung cancer remain poorly understood. Lentiviral vectors for overexpression and knockdown of phosphoenolpyruvate carboxykinase 2 (PCK2), solute carrier family 38 member 2 (SLC38A2), and CEBPB were constructed. Transwell, flow cytometry, Western blotting, and dual-luciferase reporter assays were used to investigate the regulatory relationship between PCK2 and SLC38A2 under Glu-D, as well as their effects on cellular glutamine metabolism, glycolysis, and malignant cell behaviors. PCK2 and SLC38A2 were highly expressed in human adenocarcinomas tissues. PCK2 upregulated SLC38A2 expression, though this effect was indirect. Under Glu-D, knockdown of PCK2 or SLC38A2 significantly reduced cellular glutamine utilization, inhibited glycolysis, and suppressed malignant cell behaviors. Treatment with an AMP-activated protein kinase (AMPK) inhibitor or knockdown of CEBPB produced similar effects. PCK2 activated AMPK, which increased downstream SLC38A2 expression by activating the transcription factor CEBPB.

Herein, we examine how LAMC2 contributes to liver fibrosis and explore the molecular mechanisms in both animal and cellular models. LAMC2 was knocked down in C57BL/6J mice with CCl4-induced liver fibrosis. Rescue experiments were conducted in sh-LAMC2-treated and recilisib (PI3K/Akt agonist)-treated mice. The transcription factors associated with LAMC2 in liver fibrosis were predicted and verified. Transforming growth factor (TGF)-β1-stimulated LX-2 cells (HSC line) were infected with lentiviral vectors for in vitro assays. LAMC2, which was enriched in the PI3K/Akt pathway, was increased in the liver tissues of mice treated with CCl4, and recilisib reversed LAMC2 knockdown-mediated alleviation of liver fibrosis in these mice. LAMC2 transcription in activated HSCs was caused by structural maintenance of chromosome protein 1A (SMC1A). The inhibitory effect of SMC1A knockdown on ECM accumulation and HSC activation was mitigated by LAMC2 overexpression.

Here, we investigated the consequences of FGF23 excess in kidney disease. This study used three disease models: anti-glomerular basement membrane (anti-GBM) disease, Adriamycin nephropathy, and adenine-containing diets. Anti-GBM and Adriamycin mice and matched control mice received recombinant FGF23 (1 µg) or vehicle for six days (anti-GBM) or once (Adriamycin model), with dissection 24 h after the last injection. We established precision-cut kidney slices (PCKS) in adenine nephropathy for 24 h of treatment with recombinant FGF23 or vehicle. We assessed serum cytokines, biochemistry, and renal transcriptomes and histology of mice and patients with IgA nephropathy. RNA-Seq data and published transcriptomes underwent gene set enrichment, bulk ligand–receptor interaction analysis, and cell-type decomposition. Experimental anti-GBM disease caused decreased glomerular filtration rate, albuminuria, and renal tubular casts. FGF23 treatment increased phosphaturia and circulating soluble tumor necrosis factor receptor 1. The anti-GBM model showed FGF23-driven proinflammatory transcriptional signatures and Vcam1, Pdgfrb, and chemokine signaling, which were absent in FGF23-treated healthy mice. FGF23 increased renal macrophage content by transcriptome deconvolution and by immunofluorescence. In Adriamycin-induced nephropathy and in PCKS from adenine nephropathy, short-term FGF23 excess increased proinflammatory transcripts. Human data revealed associations between circulating FGF23 and renal immune cell infiltration. We found FGF23-driven renal patterns of proinflammatory gene and protein expression or leukocyte overabundance.

Through bioinformatics approaches (including weighted gene co-expression network analysis and least absolute shrinkage and selection operator regression analysis), key factor BRD4 was identified from the Gene Expression Omnibus database, along with its related regulatory genes and Super-enhancer.

Animal experiments further confirmed the efficacy of GNE-987 in inhibiting T-ALL progression by regulating HCP5.

First, we characterized the complement of transcription factors contained in EVs derived from human embryonic and induced pluripotent stem cell lines and subsequently treated MCF7, A431, MDA-MB-231, and DLD-1 cancer cell lines with the EVs derived from these pluripotent stem cell lines. For EV-treated MDA-MB-231 and DLD-1 cells, we found a decrease in the protein expression of CD44 and C24, which are accepted markers for cancer cell populations enriched with tumor-initiating cells, a result that corresponds to the previous reports. However, for EV-treated MCF7 and A431 cells, there was an increase in the protein expression of CD44 and C24 instead, with a corresponding increase in clonogenicity and resistance to a panel of anticancer drugs, when compared to non-exosome-treated cells. When subcutaneously implanted in nude mice, EV-treated MCF7 cells gave rise to tumors of larger size than untreated cells. The cell type-dependence of the effect of hPSC-derived EV treatment was postulated to be due to occurrence of an EMT for cells located at different locations along the epithelial–mesenchymal spectrum, leading to either an increase or decrease in tumorigenicity.
