Silencing ESRP1 expression promotes caspase-independent cell death via nuclear translocation of AIF in colon cancer cells.

Epithelial splicing regulatory protein 1 (ESRP1) is overexpressed in the majority of cancer types, while downregulated in a few cancers, thus it has emerged as a tumorigenic or a tumor suppressor depending on disease context and cell type. Moreover, the underlying molecular mechanism of ESRP1 is poorly understood in cancer progression. Here, we initially analyzed Clinical Proteomic Tumor Analysis Consortium (CPTAC), colon tissue microarray, and colon cancer cells to evaluate the ESRP1 expression levels in colorectal cancer subtypes.

The inflammation response and risk associated with aflatoxin B1 contamination was minimized by insect peptide CopA3 treatment and act towards the beneficial health outcomes.

This study focused on the possible chemo-preventive effects of insect peptide CopA3 on normal human colon cells against the inflammation induced by the toxic environmental pollutant aflatoxin B1 (AFB1). In the study, we used CCD 841 CoN normal human colon cells to investigate the cytotoxic effect induced by AFB1 and elucidated the negative impact of AFB1 exposure on the cell cycle progression. Further, we also carried out the in-vivo experiment, where male BALB/c mice were administrated with AFB1 to induce inflammation associated cancer like phenotype and the dietary effect of CopA3 was evaluated on the early stages of AFB1-induced hepatotoxicity and inflammation in colon tissues.

In vitro and in vivo studies on potentiation of curcumin-induced lysosomal-dependent apoptosis upon silencing of cathepsin C in colorectal cancer cells.

Cathepsins are lysosomal acid hydrolases that make crucial contributions to tumor progression through a variety of signaling mechanisms, including autophagy, cell survival, chemotherapeutic resistance, and metastasis. Herein, we report that cathepsin C (CTSC) silencing upregulates the anticancer potential of curcumin in colorectal cancer cells (CRCs) both in vitro and in athymic mice xenografts. Curcumin treatment enhances CTSC level in CRCs; however, CTSC silencing with subsequent curcumin treatment (sequential treatment) induces ER stress and autophagic dysregulation accompanied by lysosomal permeabilization and ROS generation.
