Outline Activities
The Department of Health Science Laboratory Technology is working to develop the infrastructure of clinical chemistry and new measurement methods. In addition, mitochondrial research is being conducted as basic research. Mitochondrial DNA encodes the electron-transfer subunit that synthesizes ATP and is essential for cells to exist and function normally. Mitochondria are the largest site of reactive oxygen species generation in the cell, and mitochondrial DNA there is subject to very strong oxidative damage, and the concept that mitochondrial DNA mutations play an important role in the development and metastasis of diseases such as cancer, as well as in individual aging, is accepted. Functional analysis of genes involved in mitochondrial DNA replication, transcription, and translation is underway. Specifically, we are focusing on the mitochondrial ribosome-binding ERAL1 gene, which regulates translation, and the RNA-binding LRP130 gene. Functional analysis includes measurement of mitochondrial function (membrane potential, generation of reactive oxygen species, cell survival, and cell cycle) when gene expression is decreased by siRNA introduction, and functional evaluation (2) The CSD (cold shock domain) family of proteins has a nucleic acid binding domain consisting of approximately 78 amino acids that is highly conserved from E. coli to humans. CSD family proteins are ubiquitous proteins with a nucleic acid-binding domain consisting of about 78 amino acids that are highly conserved from E. coli to humans, and are expressed in many proliferating cells. In this study, (1) YB-1 knockout mice were generated and their functions were elucidated. Homozygous YB-1 knockout mice were embryonic lethal. (2) YB-1 was expressed almost throughout the mouse fetus by in situ hybridization. (3) YB-1 binds to the outer mitochondrial membrane and is involved in translation. (4) When YB-1 knockout fibroblasts were generated, cell proliferation was also decreased in experiments using YB-1 siRNA, confirming that the expression of EF-1 was upregulated upon YB-1 siRNA transfection. This suggests that YB-1 is deeply involved in cell proliferation, suggesting that YB-1 affects the expression of various proteins at the translational level. Furthermore, (5) YB1 was found to harbor a variety of microRNAs. This suggests that YB1 may be a potential molecular target in cancer, which could serve as a basis for new drug design. (6) Functional analysis of the mitochondrial matrix protein p32: From the individual level to the molecular level, we will examine how the mitochondria of intracellular organelles affect cells and individuals (7) Elucidation of new molecular mechanisms inferred from analysis of tissue-specific knockout mice of p32
