Cloned fragments of Xenopus laevis mitochondrial DNA and Pleurodeles waltlii mitochondrial cDNAs have been hybridized together and with mouse mtDNA. In the three cases cross-hybridization was observed. The overall organization of the X. laevis fragments appeared to be co-linear with the mouse mtDNA, most sequences being conserved except for the D-loop and the URF6 regions. The use of mouse mtDNA has enabled us to identified several mitochondrial genes in X. laevis and P. waltlii.

The 40S ribosomal subunit recycling pathway is an integral link in the cellular quality control network, occurring after translational errors have been corrected by the ribosome-associated quality control (RQC) machinery. Despite our understanding of its role, the impact of translation quality control on cellular metabolism remains poorly understood. Here, we reveal a conserved role of the 40S ribosomal subunit recycling (USP10-G3BP1) complex in regulating mitochondrial dynamics and function.

The application of regenerative therapy through stem cell transplantation has emerged as a promising avenue for the treatment of diabetes mellitus (DM). Transplanted tissue homeostasis is affected by disturbances in the clock genes of stem cells. The aim of this study is to investigate the diurnal variation in mitochondrial genes and function after transplantation of adipose-derived mesenchymal stem cells (T2DM-ADSCs) from type 2 diabetic patients into immunodeficient mice.

Cervical cancer poses a substantial threat to women's health, underscoring the necessity for effective therapeutic agents with low toxicity that specifically target cancer cells. As cancer progresses, increased glucose consumption causes glucose scarcity in the tumor microenvironment (TME). Consequently, it is imperative to identify pharmacological agents capable of effectively killing cancer cells under conditions of low glucose availability within the TME.
