Summary: The fusion protein SYNJ2BP-COX16 promotes breast cancer progression through the phosphorylation of DRP1 and subsequent induction of mitochondrial fission. SUMOylation of SYNJ2BP-COX16 recruits DRP1 to mitochondria and enhances its SUMOylation and phosphorylation, leading to mitochondrial fission.

Summary: SIRT1 is downregulated in oral cancer cells, leading to drug resistance. Downregulation of SIRT1 inhibits mitochondrial fission and promotes hyperfused mitochondrial networks, suppressing apoptosis. Overexpression of SIRT1 reverses mitochondrial hyperfusion and induces apoptosis. Gallic acid can counteract CDDP-mediated apoptosis inhibition by inhibiting mitochondrial hyperfusion. SIRT1 overexpression resensitizes CDDP-resistant cells to apoptosis.

Summary: The expression of Rab32 is significantly upregulated in GBM and is positively correlated with tumor malignancy and poor prognosis. Knockdown of Rab32 attenuates the migration and invasion capability of GBM and suppresses the expression of invasion-related proteins and mesenchymal transition markers. Rab32 regulates ERK1/2/Drp1-dependent mitochondrial fission and promotes migration and invasion of GBM.

Summary: Ovarian cancer is a leading cause of cancer-related female mortality. Ets1, a transcription factor, promotes epithelial to mesenchymal transition (EMT) and serves as a potential malignancy marker in ovarian cancer. Our study reveals that Ets1 regulates mitochondrial fission-fusion dynamics by augmenting Drp1 through direct binding at the DNM1L (DRP1) promoter. Increased Drp1 levels due to Ets1 overexpression lead to reduced mitochondrial load and compromised ATP synthase expression, resulting in a shift towards glycolysis. Additionally, inhibiting mitochondrial fission through Drp1 inhibition mitigates Ets1-associated EMT in vitro and in vivo.

Summary: In this study, we investigated the effects of a CYB5R3 mutation in a Pomeranian dog family with hereditary methemoglobinemia. The mutant enzyme showed decreased heat stability and increased susceptibility to trypsin hydrolysis, suggesting a higher sensitivity to temperature-dependent denaturation compared to the wild-type form. These findings suggest that the unstable mutant enzyme properties with normal enzymatic activity may be associated with hereditary methemoglobinemia in the Pomeranian dog family.

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.
