PLUNC downregulates the expression of PD-L1 by inhibiting the interaction of DDX17/β-catenin in nasopharyngeal carcinoma.

Background: Nasopharyngeal carcinoma (NPC) is characterized by high programmed death-ligand 1 (PD-L1) expression and abundant infiltration of non-malignant lymphocytes, which renders patients potentially suitable candidates for immune checkpoint blockade therapies. Palate, lung, and nasal epithelium clone (PLUNC) inhibit the growth of NPC cells and enhance cellular apoptosis and differentiation. Currently, the relationship between PLUNC (as a tumor-suppressor) and PD-L1 in NPC is unclear.

MAL2 (myelin and lymphocyte protein 2) and rab17 have been identified as hepatocellular carcinoma tumor suppressors. However, little is known how their functions in hepatic polarized protein sorting/trafficking translates into how they function in the epithelial to mesenchymal transition and/or the mesenchymal to epithelial transition in metastases. To investigate this, we expressed MAL2 and rab17 alone or together in hepatoma-derived Clone 9 cells (that lack endogenous MAL2 and rab17).

Coumarins, a group of naturally occurring compounds, have been reported to demonstrate anticancer potential. These substances, distinguished by their combined benzene and α-pyrone rings, have been demonstrated to impact multiple cellular mechanisms essential for the initiation and advancement of cancer. These agents work in different ways that prevent different tumor cells from growing, spreading, and increasing.

Objective: Endometrial cancer (EC) shows substantial heterogeneity in their immune microenvironment. BHLHE22 is consistently hypermethylated in EC and high expression of BHLHE22 is likely to be immunosuppressive in the tumor microenvironment. Herein, we evaluated expression of BHLHE22, programmed cell death ligand-1 (PD-L1), CD8, CD68 and mismatch repair proteins in EC.

Th/Th polarisation and suppressor of cytokine signalling-3 (SOCS3) are important indicators of the humoral and cellular immune system activity in cows. The aim of this study was to determine the correlation of postpartum diseases with the levels of Th/Th polarisation and SOCS3 at the time of parturition. The study examined 180 cows (90 with normal parturition [NP] and 90 with dystocia [D]).
