Hepatocyte growth factor activator inhibitor type 1 (HAI-1), which is encoded by the SPINT1 gene, is a membrane-associated serine proteinase inhibitor abundantly expressed in epithelial tissues. We had previously demonstrated that HAI-1 is critical for placental development, epidermal keratinization, and maintenance of keratinocyte morphology by regulating cognate proteases, matriptase and prostasin. After performing ultrastructural analysis of Spint1-deleted skin tissues, our results showed that Spint1-deleted epidermis exhibited partially disrupted epidermal basement-membrane structures.

Chronological lifespan (CLS) in budding yeast Saccharomyces cerevisiae, which is defined as the time nondividing cells in saturation remain viable, has been utilized as a model to study post-mitotic aging in mammalian cells. CLS is closely related to entry into and maintenance of a quiescent state. Many rearrangements that direct the quiescent state enhance the ability of cells to endure several types of stress.

Purpose: N6-methyladenosine (m6A) modification, one of the most common epigenetic modifications in eukaryotic mRNA, has been shown to play a role in the development and function of the mammalian nervous system by regulating the biological fate of mRNA. METTL3, the catalytically active component of the m6A methyltransferase complex, has been shown to be essential in development of in the retina. However, its role in the mature retina remains elusive.

The importance of manganese superoxide dismutase (Mn-SOD), an evolutionarily ancient metalloenzyme that maintains the integrity and function of mitochondria, was studied in oxidative stress-treated cultures. Deletion of the Mn-SOD gene () increased both the menadione sodium bisulfite (MSB)-elicited oxidative stress and the deferiprone (DFP)-induced iron limitation stress sensitivity of the strain. Moreover, DFP treatment enhanced the MSB sensitivity of both the gene deletion mutant and the reference strain.

is a dimorphic fungus that specifically infects , causing stem swelling and the formation of an edible fleshy stem known as jiaobai. The pathogenicity of is closely associated with the development of jiaobai and phenotypic differentiation. Msb2 acts as a key upstream sensor in the MAPK (mitogen-activated protein kinase) signaling pathway, playing critical roles in fungal hyphal growth, osmotic regulation, maintenance of cell wall integrity, temperature adaptation, and pathogenicity.
