Background: Lipid metabolism is crucial in cancer progression. Lipid droplets (LDs) generated in cancer cells can act as protective mechanisms through alleviating lipotoxicity under stress conditions. We previously developed IC2 from the Chinese medicine icaritin as an inhibitor of stearoyl-CoA desaturase 1 (SCD1).

Antiangiogenic drugs may cause vascular normalization and correct hypoxia in tumors, shifting cells to mitochondrial respiration as the primary source of energy. In turn, the addition of an inhibitor of mitochondrial respiration to antiangiogenic therapy holds potential to induce synthetic lethality. This study evaluated the mitochondrial inhibitor ME-344 in combination with bevacizumab in patients with refractory metastatic colorectal cancer (mCRC).

Anhui Provincial Center for Neural Regeneration Technology and New Medical Materials Engineering Research, Bengbu Medical University, Bengbu 233000, China.
Objectives: To investigate the role of mitochondrial autophagy disorder caused by deletion of E3 ubiquitin ligase Parkin in neuroinflammation in a mouse model of MPTP-induced Parkinson's disease (PD).
Methods: Wild-type (WT) male C57BL/6 mice and Parkin mice were given intraperitoneal injections with MPTP or PBS for 5 consecutive days, and the changes in motor behaviors of the mice were observed using open field test. The effects of Parkin deletion on PD development and neuroinflammation were evaluated using immunofluorescence and Western blotting.

Children's Medical Center, Xiangya Hospital, Central South University, Changsha 410008, China.
Objectives: To explore the mechanism by which Wiskott-Aldrich syndrome protein family verprolin-homologous protein 1 (WAVE1) regulates lipopolysaccharide (LPS)-induced mitochondrial metabolic abnormalities and inflammatory responses in macrophages.
Methods: Macrophage cell lines with overexpressed WAVE1 (mouse BMDM and human THP1 cells) were prepared. The macrophages were treated with LPS (500 ng/mL) to simulate sepsis-induced inflammatory responses.

Species relationships and speciation have traditionally been represented by phylogenetic trees, but not all evolutionary histories fit into bifurcating divergence models. Introgressive hybridization challenges this assumption by sometimes [or maybe often] leading to mitochondrial introgression, wherein one species' mitochondrial genome is entirely replaced by another's (mitochondrial capture). Such processes result in mitonuclear discrepancies, complicating species delimitation and phylogenetic inference.
