Recent advances in biomarkers for senescence: Bridging basic research to clinic.

Geriatr Gerontol Int

January 2025

Department of Advanced Senotherapeutics and Department of Cardiovascular Biology and Medicine, Juntendo University Graduate School of Medicine, Tokyo, Japan.

In this review, we review the current status of biomarkers for aging and possible perspectives on anti-aging or rejuvenation from the standpoint of biomarkers. Aging is observed in all cells and organs, and we focused on research into senescence in the skin, musculoskeletal system, immune system, and cardiovascular system. Commonly used biomarkers include SA-βgal, cell-cycle markers, senescence-associated secretory phenotype (SASP) factors, damage-associated molecular patterns (DAMPs), and DNA-damage-related markers.

Background: In randomized clinical trials, multiple-testing procedures, composite endpoints, and prioritized outcome approaches are increasingly used to analyze multiple binary outcomes. Previous studies have shown that correlations between outcomes influence their sample size requirements. Although sample size is an important factor affecting the choice of statistical methods, the power and required sample sizes of methods for analyzing multiple binary outcomes have yet to be compared under the influence of outcome correlations.

Immune checkpoint inhibitors against PD-1/PD-L1 are highly effective in immunologically hot tumours such as triple-negative breast cancer, wherein constitutive DNA damage promotes inflammation, while inducing PD-L1 expression to avoid attack by cytotoxic T cells. However, whether and how PD-L1 regulates the DNA damage response and inflammation remains unclear. Here, we show that nuclear PD-L1 activates the ATR-Chk1 pathway and induces proinflammatory chemocytokines upon genotoxic stress.

ATG9A facilitates the closure of mammalian autophagosomes.

J Cell Biol

February 2025

Autophagy, Inflammation and Metabolism Center of Biomedical Research Excellence, University of New Mexico Health Sciences Center, Albuquerque, NM, USA.

Canonical autophagy captures within specialized double-membrane organelles, termed autophagosomes, an array of cytoplasmic components destined for lysosomal degradation. An autophagosome is completed when the growing phagophore undergoes ESCRT-dependent membrane closure, a prerequisite for its subsequent fusion with endolysosomal organelles and degradation of the sequestered cargo. ATG9A, a key integral membrane protein of the autophagy pathway, is best known for its role in the formation and expansion of phagophores.

Background: MET gene exon 14 skipping was identified as a potential driver mutation that occurs in approximately 3%-4% of patients with nonsmall cell lung cancer (NSCLC), typically in the absence of other driver mutations. Capmatinib and tepotinib were the first MET- tyrosine kinase inhibitors (MET-TKIs) approved by the FDA and PMDA, specifically for patients with metastatic NSCLC. Several studies have reported acquired resistance after MET-TKI treatment for MET mutation-positive NSCLC.

Tolerance to foreign molecules is primarily induced through three pathways: anergy, active suppression, and clonal deletion. The immaturity of gut functions, including digestion and barrier protection against foreign molecules during early infancy, is closely linked to the induction of tolerance. A significant number of undigested peptides can pass through leaky gut walls during this period, making it an opportune time to introduce active suppression and clonal deletion in the intestine.

How many cases do young pediatric surgeons need to experience to achieve autonomy in performing pediatric endoscopic surgery? A nationwide survey to establish an ideal curriculum for pediatric endoscopic surgery in Japan.

Pediatr Surg Int

December 2024

Department of Pediatric Surgery, Research Field in Medical and Health Sciences, Medical and Dental Area, Research and Education Assembly, Kagoshima University, 8-35-1, Sakuragaoka, Kagoshima City, 890-8520, Japan.

Purpose: To ensure the safe prevalence of pediatric endoscopic surgery in Japan, a training curriculum should be established. In addition, the number of pediatric surgical cases is decreasing due to the decreasing birth rate in Japan, and it is necessary to clarify the number of surgical cases required for young pediatric surgeons to achieve autonomy in pediatric endoscopic surgery.

Methods: An online nationwide survey was conducted among young pediatric surgeons with 3-15 years of clinical experience in Japan.

The standard treatment for hormone receptor-positive breast cancer in good general condition is curative surgery followed by endocrine therapy. However, for older patients, endocrine therapy alone is sometimes chosen instead of curative surgery due to health conditions or personal preference, though this is not yet a standard approach. It is crucial to develop elderly-specific treatment strategies, potentially establishing endocrine therapy alone as a standard option.

Article Synopsis
  • The study analyzed outcomes for pediatric patients with blunt liver and spleen injuries (BLSI) treated at hospitals with and without pediatric intensive care units (PICUs) between 2008 and 2019.
  • Among the 1401 patients, 30-day mortality rates were lower in hospitals with PICUs (0.7%) compared to those without (1.3%), and also compared to adult ICUs.
  • Overall, while adverse events were infrequent, the findings suggested that treatment in hospitals with PICUs may lead to better outcomes for pediatric patients with BLSI.

Background: Reducing premature noncommunicable disease (NCD) mortality is a global challenge. Sodium is thought to increase risk of NCDs via an effect of salt per se or high-salt foods on hypertension-induced cardiovascular disease (CVD) and gastrointestinal cancer. Further, relative risk of CVD is reportedly more closely associated with sodium-to-potassium ratio than that with sodium alone.
