Yoshitaka Nagahama spends much of his time researching Sexual differentiation, Endocrinology, Ovary, Genetics and Molecular biology. His studies deal with areas such as Zoology, XY sex-determination system, Sexual characteristics, Sex change and Cell biology as well as Sexual differentiation. His Endocrinology research is multidisciplinary, relying on both Oocyte, Sex reversal and General transcription factor.
The various areas that Yoshitaka Nagahama examines in his Ovary study include Tilapia, Gonad, Nile tilapia, Oreochromis and Zebrafish. His is involved in several facets of Genetics study, as is seen by his studies on Gene, Y chromosome, Oryzias, Testis determining factor and Primary sex determination. His Y chromosome research integrates issues from DMRT1 Gene and DM domain.
His main research concerns Endocrinology, Sexual differentiation, Oryzias, Cell biology and Genetics. His work carried out in the field of Endocrinology brings together such families of science as Oocyte and Vitellogenesis. The Sexual differentiation study combines topics in areas such as Gonad, Nile tilapia, Oreochromis, Sexual dimorphism and Sex reversal.
His work deals with themes such as Complementary DNA, Northern blot and Molecular biology, which intersect with Oreochromis. Oryzias is a subfield of Gene that he tackles. His Cell biology study combines topics in areas such as Autophagy, In situ hybridization, Receptor, Reporter gene and Germ cell.
The scientist’s investigation covers issues in Genetics, Oryzias, Endocrinology, Cell biology and Sexual differentiation. In his work, Gene expression profiling, Tilapia and Candidate gene is strongly intertwined with Nile tilapia, which is a subfield of Genetics. The study incorporates disciplines such as Otic vesicle, In situ hybridization, Somite, RSPO1 and Embryo in addition to Oryzias.
His biological study focuses on Ovary. His study in Cell biology is interdisciplinary in nature, drawing from both Autophagy, Organogenesis, Estrogen and Zebrafish. His research in Sexual differentiation intersects with topics in Germinal epithelium, Cell Transdifferentiation, Gonad, Sexual dimorphism and Sex reversal.
His primary scientific interests are in Genetics, Oryzias, Sexual differentiation, Gene and Y chromosome. The concepts of his Genetics study are interwoven with issues in Molecular biology, Tilapia and Oreochromis. His Oryzias research is multidisciplinary, relying on both Endocrinology, Ovary, RSPO1, Sex reversal and DM domain.
His Endocrinology research incorporates elements of Somatic cell, Germline, Transdifferentiation, Stem cell and Yolk. Yoshitaka Nagahama interconnects Gene expression profiling, Nile tilapia, Sexual dimorphism and Candidate gene in the investigation of issues within Sexual differentiation. His Y chromosome study combines topics in areas such as Phenotype, Regulation of gene expression and Sex Determination Process.
