Cancer mutations rewire the RNA methylation specificity of METTL3-METTL14.

Chemical modification of RNAs is important for posttranscriptional gene regulation. The METTL3-METTL14 complex generates most -methyladenosine (mA) modifications in messenger RNAs (mRNAs), and dysregulated methyltransferase expression has been linked to cancers. Here we show that a changed sequence context for mA can promote oncogenesis.

Health and Wellness Coaching Can Improve Tobacco Quit Rates and Weight Management Efforts in an Employee Population.

Purpose: This study aims to investigate gender differences in tobacco quit rates and weight gain among employees undergoing a cessation program with a health and wellness coach.

Design: This project was a retrospective observational study of an employee population.

Setting: All data were collected during health coaching sessions by nationally certified health coaches.

Coordinated translational control of multiple immune checkpoints by the integrated stress response pathway in lung cancer.

Unlabelled: The integrated stress response (ISR) is an adaptive pathway hijacked by cancer cells to survive cellular stresses in the tumor microenvironment. ISR activation potently induces Programmed Death Ligand 1 (PD-L1), leading to suppression of anti-tumor immunity. Here we sought to uncover additional immune checkpoint proteins regulated by the ISR to elucidate mechanisms of tumor immune escape.

Dysregulation of FicD AMPylation causes diabetes by disrupting pancreatic endocrine homeostasis.

Bi-functional enzyme FicD regulates the endoplasmic reticulum chaperone BiP using AMPylation and deAMPylation during ER homeostasis and stress, respectively. Human FicD with an arginine-to-serine mutation disrupts FicD deAMPylation activity resulting in severe neonatal diabetes. We generated the mutation in mice to create a pre-clinical murine model for neonatal diabetes.

Upregulation of Fatty Acid Synthase Increases Activity of β-Catenin and Expression of NOTUM to Enhance Stem-like Properties of Colorectal Cancer Cells.

Dysregulated fatty acid metabolism is an attractive therapeutic target for colorectal cancer (CRC). We previously reported that fatty acid synthase (FASN), a key enzyme of de novo synthesis, promotes the initiation and progression of CRC. However, the mechanisms of how upregulation of FASN promotes the initiation and progression of CRC are not completely understood.
