SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

open access: yesFEBS Open Bio, EarlyView.
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

Metformin promotes mitochondrial integrity through AMPK‐signaling in Leber's hereditary optic neuropathy

open access: yesFEBS Open Bio, EarlyView.
Metformin mediates mitochondrial quality control in Leber's hereditary optic neuropathy (LHON) fibroblasts carrying mtDNA mutations. At therapeutic levels, metformin activates AMPK signaling to restore mitochondrial dynamics by promoting fusion and restraining fission, while preserving mitochondrial mass, enhancing autophagy/mitophagy and biogenesis ...

Protein Tyrosine Phosphatase 4A1 (PTP4A1) Regulates Early Events in Colorectal Cancer Intraperitoneal Dissemination in the Aged Male Host

open access: yesAging and Cancer, EarlyView.
Colorectal cancer (CRC) mortality is highest in aged males. Pre‐clinical data comparing CRC i.p. metastasis in cohorts of young and aged, male and female mice support these finding. Bottom‐up proteomics of peritoneal mesothelial cells identified PTP4A1 as highly expressed in aged males and a role for PTP4A1 in heterotypic cell:cell adhesion was ...

Breast Cancer and Aging: Understanding the Complex Relationship and Implications for Prevention and Screening

open access: yesAging and Cancer, EarlyView.
ABSTRACT Background Breast cancer is a multifactorial disease that affects many women worldwide. Age is the most important risk factor for breast cancer, with an increased incidence markedly after the age of 50. The relationships of aging to breast cancer have been thoroughly examined, and notable connections regarding various age‐related changes in ...

Trends and Disparities in Lung Cancer and Respiratory Failure Mortality in the United States: A 24‐Year Retrospective Study

open access: yesAging and Cancer, EarlyView.
Mortality from lung cancer and respiratory failure in US adults declined until 2010 but increased thereafter, with notable disparities by sex, race, region, and urbanicity. This 24‐year analysis highlights rising post‐2010 mortality in women, non‐Hispanic Whites, and urban areas, underscoring the need for targeted public health interventions.

Enhancing Oncological Care for India's Aging Population: Addressing the Complex Needs of Older Adults With Cancer

open access: yesAging and Cancer, EarlyView.
Aging‐associated physiological and molecular alterations pose significant challenges in cancer management among India's elderly. Limited geriatric oncology expertise, financial constraints, and inadequate specialized care exacerbate disparities. Strategic expansion of insurance coverage, integration of palliative care, and infrastructural advancements ...
