Pancreatic adenocarcinoma (PAAD) is one of the most hazardous cancers in digestive system, and the prognosis is notoriously bad. Increasing evidences indicate that Laminin Subunit Gamma 2 (LAMC2) is critical for the initiation and the growth of various sorts of human cancers. However, the involved molecular pathways of LAMC2 in PAAD are still poorly understood. In this study, prediction programs and databases were employed to conduct pan-cancer analysis. Multiple variations of human malignancies showed increased LAMC2 expression, which was positively correlated to a poor prognosis in PAAD. Moreover, LAMC2 was positively correlated with the biomarkers of immune cells including CD19, CD163, and NOS2 in PAAD. The lncRNA C5orf66 /PTPRG-AS1- miR-128-3p -LAMC2 axis was identified to be a potential upstream regulatory pathway of LAMC2 in PAAD. Furthermore, LAMC2 upregulation in PAAD was associated with PD-L1 expression, indicating promoting carcinoma immune cell infiltration. Our study elucidated prognostic and immunological values of LAMC2 in PAAD, providing a promise target for PAAD treatment.

Poor outcomes and chemotherapy resistance for patients with pancreatic adenocarcinoma (PAAD) are a challenge worldwide, and new or improved prognostic biomarkers are urgently required. Individual laminin family members have been established as cancer-associated markers, predicting patient outcomes in many cancer types, including PAAD. Here, we used multiple modalities including RNAseq and gene chip, and genomic and proteomic data to examine the relationships of all laminin genes in PAAD with clinical outcomes.

The extracellular matrix (ECM) is a vital component of the tumor microenvironment, which interplays with stromal and tumor cells to stimulate the capacity of cancer cells to proliferate, migrate, invade, and undergo angiogenesis. Nevertheless, the crucial functions of ECM-related genes (ECMGs) in pancreatic adenocarcinoma (PAAD) have not been systematically evaluated. Hence, a comprehensive evaluation of the ECMGs is required in pan-cancer, especially in PAAD.

Intraductal papillary mucinous neoplasm (IPMN) is a common pancreatic precancerous lesion, with increasing incidence in recent years. However, the mechanisms of IPMN progression into invasive cancer remain unclear. The mRNA expression data of IPMN/PAAD patients were extracted from the TCGA and GEO databases.

Pancreatic adenocarcinoma (PAAD) is one of the most common malignant tumors with poor prognosis worldwide. Mounting evidence suggests that the expression of lncRNAs and the infiltration of immune cells have prognostic value for patients with PAAD. We used Gene Expression Omnibus (GEO) database and identified six genes (COL1A2, ITGA2, ITGB6, LAMA3, LAMB3, and LAMC2) that could affect the survival rate of pancreatic adenocarcinoma patients.
