遺伝子研究の概要
METTL3, short for methyltransferase-like 3, is the sole catalytic subunit of the methyltransferase complex that catalyzes N6-methyladenosine (m6A) modification, the most abundant mRNA modification. This modification is involved in regulating RNA stability, translation efficiency, and thus impacts various biological processes like cell differentiation, development, and disease-related pathways [2].
In multiple disease models, METTL3 shows distinct effects. In colon cancer, myeloid-specific deletion of METTL3 attenuated tumor growth in mice, suggesting its role in promoting tumor-infiltrating myeloid cell-mediated immunosuppression [1]. In small cell lung cancer, high METTL3 expression was associated with chemoresistance, and its knockdown reversed this phenotype, indicating its function in promoting mitophagy-mediated chemotherapy resistance [3]. In sepsis-associated lung injury, inhibition of METTL3 via knockdown or targeted inhibition suppressed lactate-induced ferroptosis in alveolar epithelial cells and mitigated lung injury in septic mice [4]. In breast cancer, METTL3 knockdown reduced PD-L1 mRNA stability, enhancing anti-tumor immunity [5]. In papillary thyroid cancer, down-regulation of METTL3 was related to malignant progression, and restoring its expression restrained tumor growth [6]. In diabetic nephropathy, podocyte-conditional knockout of METTL3 alleviated podocyte injury and albuminuria [7]. In intrahepatic cholangiocarcinoma, METTL3 knockdown inhibited tumor progression [8].
In conclusion, METTL3-mediated m6A modification significantly influences multiple disease-related biological processes. Studies using gene knockout (KO) or conditional knockout (CKO) mouse models have been crucial in revealing METTL3's role in diseases such as cancer, sepsis-associated lung injury, and diabetic nephropathy. These models help us understand the complex functions of METTL3, providing potential therapeutic targets for these diseases.
