Independent, cooperative regulation of cellulolytic genes by paralogous transcription factors ClbR and ClbR2 in Aspergillus aculeatus
Biosci Biotechnol Biochem. 2023 Nov 8:zbad156. doi: 10.1093/bbb/zbad156. Online ahead of print.ABSTRACTThe cellobiose-responsive regulator ClbR, a Zn(II)2Cys6 binuclear-cluster transcription factor, is a positive regulator of carbohydrate-active enzyme (CAZyme) genes responsive to cellulose in Aspergillus aculeatus. Because Zn(II)2Cys6 transcription factors tend to dimerize with proteins of the same family, we searched for a counterpart of ClbR and identified ClbR2, which is 42% identical to ClbR, as an interacting partner of ClbR by yeast two-hybrid screening. Genetic analyses suggested that ClbR and ClbR2 cooperatively r...

Mouse TMC4 is involved in the detection of chloride taste of salts
Biosci Biotechnol Biochem. 2023 Nov 8:zbad155. doi: 10.1093/bbb/zbad155. Online ahead of print.ABSTRACTLicking behavior with various salts in Tmc4 knockout (KO) mice was observed. In Tmc4 KO mice, a significant decrease in sensitivity to chloride salts, such as NaCl, KCl, and NH4Cl, was observed, while no significant decrease in sensitivity to Na gluconate was observed. This finding suggests that TMC4 may be involved in the detection of chloride taste.PMID:37947260 | DOI:10.1093/bbb/zbad155 (Source: Bioscience, Biotechnology, and Biochemistry)

Procyanidins and sensory nutrition; Do procyanidins modulate homeostasis via astringent taste receptors?
Biosci Biotechnol Biochem. 2023 Nov 1:zbad154. doi: 10.1093/bbb/zbad154. Online ahead of print.ABSTRACTLong-term intake of procyanidins has been suggested to reduce the risk of cardiovascular disease, dementia, and sensory function decline associated with aging. However, most of the ingested procyanidins are not absorbed and are excreted in the feces, so the mechanism of their beneficial impact is unknown. Procyanidins are the components of astringency in plant foods and their stimulation appears to be directly transmitted to the central nervous system via sensory nerves. Recent attention has been focused on the taste rece...

α-Tocotrienol in rice bran enhances steroidogenesis in mouse Leydig cell via increased gene expression of steroidogenic acute regulatory protein and induction of its mitochondrial translocation
Biosci Biotechnol Biochem. 2023 Oct 25:zbad153. doi: 10.1093/bbb/zbad153. Online ahead of print.ABSTRACTRice is a staple food in the Asian region and one of the world's major energy sources. Testosterone is a steroid hormone that maintains physical, sexual, and cognitive ability and its decline causes health problems like late-onset hypogonadism. Evaluation of various grain extracts showed rice bran to stimulate testosterone secretion from Leydig model cell. α-Tocotrienol was found as a bioactive compound in rice bran, and mechanistic analysis showed the stimulation of steroid hormone synthesis through enhanced gene expre...

Salmon nasal cartilage proteoglycan stimulates hair growth
In this study, hair growth was enhanced by daily oral ingestion of salmon nasal cartilage proteoglycan (PG) in mice. PG stimulated VEGF production in human follicle dermal papilla cells through IGF-1 receptor signaling, suggesting the possibility of hair loss improvement by PG ingestion.PMID:37881018 | DOI:10.1093/bbb/zbad149 (Source: Bioscience, Biotechnology, and Biochemistry)

Biosci Biotechnol Biochem. 2023 Oct 25:zbad150. doi: 10.1093/bbb/zbad150. Online ahead of print.ABSTRACTStrigolactones (SLs) are a class of terpenoid lactones initially identified as seed germination stimulants for root parasitic plants more than 50 years ago. Long after this initial discovery, SLs were re-characterized as the symbiotic signals for arbuscular mycorrhizal fungi that supply inorganic nutrients, such as phosphate, to their host plants. In 2008, SLs were found to be endogenous plant hormones that regulate shoot branching in plants. The discovery of SLs as a new class of plant hormones has significantly advance...
