LAMB1 (Laminin Subunit Beta 1)

Cross-organ single-cell integration prioritizes liver-selective stromal circuitry and nominates hepatocyte-FB axes (HGF-MET, AGT-AGTR1B) as plausible links between fibrogenic remodeling and a pro-tumorigenic niche, yielding testable hypotheses at the interface of regeneration, RAS biology, and tumor initiation.

Sarcomatoid component-specific DNA hypomethylation of TSKU, PLAU, PLEKHG4, RPSAP52, XBP1 and TRIM2 was correlated with both recurrence-free and overall survival. These data suggest that the DNA methylation alterations associated with sarcomatoid change may participate in malignant progression and determine patient outcome.

Additionally, serum LAMB1 demonstrates superior diagnostic performance compared to the classic HCC marker alpha-fetoprotein. LAMB1 represents a promising therapeutic target for HCC, and also serves as a potential circulating biomarker for liver cancer screening in clinics.

A specific EV subpopulation enriched in CD147 and LAMB1-referred to as Excretion EVs-carried H3.2 (H3C14) but did not induce GCB resistance in recipient cells, suggesting their primary role in eliminating proteins associated with tumour progression and drug resistance. These findings highlight the role of EV-mediated H3C14 excretion in regulating GCB resistance and suggest potential therapeutic strategies targeting EV pathways to overcome drug resistance in bladder cancer.

Our study revealed that SCAFs were strongly correlated with cancer stemness in HCC. A novel machine learning model based on senescent CAF-related genes was constructed to accurately predict prognosis in HCC patients. Furthermore, CTHRC1 was identified as a novel prognostic and therapeutic biomarker to predict poor prognosis in HCC and promote cancer stemness and metastasis through the Notch signaling pathway, with its expression being transcriptionally regulated by SOX4.

We firstly established a mGSTc01 cell line derived from C57BL/6 J mice GIST tumor offers, which closely mimicking human disease characteristics. It is a potent platform for investigating tumor microenvironment of GIST in mice model, and provides a novel way for new therapeutic discoveries in GIST.

In summary, Eth exerts anti-tumour effects by inhibiting the activation of the PI3K/AKT/mTOR pathway, which in turn activates mitochondrial apoptosis. Eth may be considered in the development of drugs for relieving colon cancer patients in the future.

LAMB1 downregulation exerted antitumor effects on glioma cells by regulating the NF-κB/HK2 axis.

High expression of LAMB1 is significantly associated with an immune-suppressive tumor microenvironment in NPC. LAMB1 enhances the proliferation, migration and invasion of NPC cells. These findings suggest that LAMB1 may serve as a prognostic biomarker for predicting NPC progression and a potential therapeutic target to enhance the efficacy of existing immunotherapies.

The cell migration and invasion of KPA mice were also similar to those of control KP mice. Arhgap39 loss could modulate the migration and invasion in some hepatocellular cancer cells, but not in those isolated from KPA mice.

Analysis of single-cell RNA sequencing (scRNA-seq) databases shows that in quiescent brain LAMB2 is predominantly expressed by BBB-associated pericytes (PCs) and endothelial cells (ECs), whereas neither cell types produce LAMB1. In contrast, in HGG, both LAMB1 and 2 are overexpressed by endothelial precursor cells, a phenotypically unique immature group, specific to proliferating hyperplastic MV.

In conclusion, a prognostic model of LUAD patients depending on the ECM receptor interaction pathway was constructed. Screening out LAMB1 can become a prognostic risk factor for LUAD patients or a potential target during LUAD treatment.
