    Sin3a regulates pancreatic β-cells fitness and function

    By Sohini Roy People with type 1 diabetes generate little to no insulin, which promotes the absorption of glucose from the blood. The transcriptional coregulator Swi-independent 3 — or Sin3 — switches on and off the genes that drive crucial biological processes during prenatal development, including cellular differentiation, maturation, survival, metabolism,… Read More

  • Colorful 3D illustration of a cell undergoing cell division. The outside of the progeny cells is bright orange/red. Green filaments spread out from each pole toward the center. The cell is getting pinched around the center; the area between the cells is blue. The background is black.

    Myosin motors regulate cell shape during division

    By Natalya Ortolano Myosin motors and long actin filaments accumulate at the center of dividing cells to constrict the membrane. When a bouncy ball deforms under the weight of your body, its rubber membrane stretches and contracts. Likewise, the membrane of a cell doubling itself prior to division must accommodate… Read More

  • 3D rendering of a few RNA viruses. The one in the center has a quarter of the top half removed, forming a little window into the inside. Inside is a few molecules of RNA. The viruses are blue/gray with red proteins on their surface (much like the spike protein of SARS-CoV-2), and the RNA molecules are yellow.

    VIR-CLASP reveals new insights into cellular mechanisms of viral immune response

    By Brad Davidson VIR-CLASP has the potential to find new therapeutic targets during infection by a wide variety of RNA viruses. RNA viruses invade cells and co-opt cellular machinery to replicate and translate their genomic material. To stave off infection until immune cells arrive, host cells rely on “intrinsic immunity… Read More

    Study explores the role of MYCN in Triple Negative Breast Cancer diagnosis and treatment

    By Mary Alice Keller Triple-negative breast cancer is a type of breast cancer that tests negative for the three receptors that are commonly found in breast cancer: estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2) receptors. The oncogene MYCN regulates cancer cell growth, proliferation, metabolism, and… Read More
