LncRNA SNHG11 Promotes Gastric Cancer Progression by Activating Wnt/β-Catenin Pathway and Oncogenic Autophagy

Long non-coding RNA small nucleolar host gene 11 (SNHG11) post-transcriptionally upregulated catenin beta 1 and autophagy related 12 through miR-483-3p/miR-1276, while the processing of pre-miR-483/pre-miR-1276 was hindered by SNHG11. SNHG11 induced GSK-3β ubiquitination through interacting with Cullin 4A to further activate the Wnt/β-catenin pathway.

TAp63α Targeting of Lgr5 Mediates Colorectal Cancer Stem Cell Properties and Sulforaphane Inhibition

Researchers investigated the role of TAp63α in colorectal cancer stem cells and the effects of sulforaphane on TAp63α. They found that TAp63α was upregulated in spheres with stem cell properties compared to the parental cells.

B7-H3 Regulates KIF15-Activated ERK1/2 Pathway and Contributes to Radioresistance in Colorectal Cancer

In vitro and in vivo functional analyses showed that B7-H3 enhanced resistance against irradiation in colorectal cancer cells by upregulating KIF15 expression via NF-κB, which activated ERK1/2 signaling, a key pathway involved in radioresistance in cancers.

Non-Muscle Myosin-2 Contractility-Dependent Actin Turnover Limits the Length of Epithelial Microvilli

Using pharmacological and genetic perturbations in cultured intestinal epithelial cells, investigators found that non-muscle myosin-2C controls the length of growing microvilli by regulating actin turnover in a manner that requires a fully active motor domain.

A Novel Role for Farnesoid X Receptor in the Bile Acid‐Mediated Intestinal Glucose Homeostasis

Bile acid‐activated farnesoid X receptor enhanced glucose uptake in intestinal epithelial cells by increasing the expression of glucose transporter 2, which depended on ERK1/2 phosphorylation via S1PR2. However, it also reduced the cell energy generation via inhibition of oxidative phosphorylation, which was crucial for intestinal glucose transport.
