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.

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice

open access: yesAging and Cancer, EarlyView.
Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.

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 ...
