FBP1 controls liver cancer evolution from senescent MASH hepatocytes.

Nature

January 2025

Laboratory of Gene Regulation and Signal Transduction, Departments of Pharmacology and Pathology, School of Medicine, University of California San Diego (UCSD), La Jolla, CA, USA.

Article Synopsis
  • Hepatocellular carcinoma (HCC) arises from liver cells (hepatocytes) that are damaged and undergoing compensatory growth, particularly due to metabolic disorders like MASH.
  • The tumor-suppressive effects of p53 and the anti-cancer role of the enzyme FBP1 are undermined in HCC, as FBP1 is commonly degraded and suppressed in tumors.
  • Key metabolic pathways involving AKT and NRF2 play a role in reversing the effects of cellular senescence, boosting the growth of HCC cells and leading to the accumulation of genetic mutations that contribute to cancer progression.

Article Synopsis
  • Inflammatory bowel diseases (IBD) like Crohn's disease and ulcerative colitis are chronic conditions affecting the intestines, leading to new treatment options through immunotherapies.
  • Recently developed S1P modulators, such as ozanimod and etrasimod, work by sequestering T cells in lymphoid tissues, reducing their migration to inflamed gut areas, which helps in controlling IBD symptoms.
  • This review highlights the role of the S1P/S1PR signaling pathway in IBD, evaluates the effectiveness and safety of current S1P modulators, and explores future treatment possibilities targeting this pathway.

Objectives: Serum creatinine (SCr) is the primary biomarker for assessing kidney function; however, it may lag behind true kidney function, especially in instances of acute kidney injury (AKI). The objective of the work is to develop Nephrocast, a deep-learning model to predict next-day SCr in adult patients treated in the intensive care unit (ICU).

Materials And Methods: Nephrocast was trained and validated, temporally and prospectively, using electronic health record data of adult patients admitted to the ICU in the University of California San Diego Health (UCSDH) between January 1, 2016 and June 22, 2024.
