Summary: Chemotherapy-induced sarcopenia is a negative prognostic factor that affects postoperative complications and quality of life in cancer patients. Cisplatin, a commonly used chemotherapy drug, causes skeletal muscle loss by affecting mitochondrial function and activating muscle-specific ubiquitin ligases Atrogin-1 and muscle RING finger 1 (MuRF1). Although p53 has been implicated in muscle atrophy, it is unclear if it plays a role in cisplatin-induced atrophy. This study investigated the effect of a p53-specific inhibitor, pifithrin-alpha (PFT-a), on cisplatin-induced muscle atrophy in C2C12 myotubes. The results showed that cisplatin increased p53 levels and upregulated the expression of p53 target genes in C2C12 myotubes. PFT-a reduced reactive oxygen species production, mitochondrial dysfunction, and the increase in the Bax/Bcl-2 ratio induced by cisplatin. However, PFT-a did not ameliorate the decrease in muscle protein synthesis. Overall, this study suggests that cisplatin-induced muscle degradation is p53-dependent, but p53 has minimal involvement in the reduction of muscle protein synthesis.

Summary: This study reveals the role of MLL1 in acute kidney injury (AKI) induced by cisplatin. The inhibition of the MLL1/WDR5 complex using MM102 improved renal function, attenuated tubular injury and apoptosis, and suppressed the phosphorylation of p53 and the decrease of E-cadherin expression. MM102 also effectively inhibited the DNA damage response triggered by cisplatin.

Summary: PUMA is a direct target in p53-mediated apoptosis and can trigger mitochondrial apoptosis through transcription-dependent and independent mechanisms. Experimental results demonstrate the interaction between PUMA peptide and the DNA binding domain of p53 inhibits the growth of a lung cancer cell line. These findings contribute to understanding the mechanism responsible for p53-mediated apoptosis.

Summary: Synthetic lethality can be used to target oncogenic drivers in cancer, and in this study, it was found that WRN helicase is required for the survival of MSI CRC cells. Depletion of WRN induces p53 and PUMA, leading to apoptosis in MSI CRC cells. The vulnerability of MSI CRCs to WRN loss is mediated by p53/PUMA-dependent apoptosis. WRN depletion or treatment with ML216 suppresses the growth of MSI CRCs in vitro and in vivo in a p53/PUMA-dependent manner.

Summary: Circular RNAs (circRNAs) play a role in intervertebral disc degeneration (IVDD) and are modified with N6-methyladenosine (m6A). We found that circGPATCH2L, which has low m6A methylation level, is upregulated in degenerative nucleus pulposus tissues. CircGPATCH2L acts as a protein decoy for TRIM28, inhibiting P53 degradation and contributing to IVDD progression. M6A-methylated circGPATCH2L is recognized and cleaved by a YTHDF2-RPL10-RNase P/MRP complex, maintaining the physiological state of nucleus pulposus cells.

Summary: Streptozotocin (STZ) is an anti-cancer drug used to treat neuroendocrine tumors (NETs). It enters pancreatic beta-cells or proximal tubular epithelial cells through GLUT2. This study demonstrated the cytotoxic effects of STZ on kidney cells and identified DNA damage and p53 signaling as underlying mechanisms. Inhibition of p53 and SGLT2 mitigated kidney injury caused by STZ, but the cytotoxic effects on pancreatic beta-cells were not affected. These findings suggest the potential use of SGLT2 inhibitors as preventive treatments for kidney injury in NET patients treated with STZ.

Summary: Doublecortin-like kinase 1 (DCLK1) is a significant prooncogenic factor that is strongly associated with the malignant progression and clinical prognosis of various cancers. DCLK1 plays important roles in stem cell marker regulation, tumor cell reprogramming, and immune evasion. However, the exact biological functions of DCLK1, especially the disparities between its alpha- and beta-form transcripts in cancer progression, remain ambiguous.
