Evolutionary Dynamics and Functional Conservation of amh Signaling in Teleost Lineages

Fishes
The anti-Müllerian hormone (amh) and its receptor, amhr2, along with the downstream bone morphogenetic protein receptors (bmprs), have been recognized as the central regulators in teleost sex determination (SD) and differentiation.

Integrated analysis of microRNA and mRNA expression profiles during the sex-differentiation sensitive period in oriental river prawn, Macrobrachium nipponense

Scientific Reports, 2017
Male oriental river prawns (Macrobrachium nipponense) grow faster than females, and therefore, reach larger sizes by harvest time. Histological observations have indicated that the sex-differentiation sensitive period (which includes the formation of the

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

Molecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Single-nucleus multiomics reveals the gene regulatory networks underlying sex determination of murine primordial germ cells

eLife
Accurate specification of female and male germ cells during embryonic development is critical for sexual reproduction. Primordial germ cells (PGCs) are the bipotential precursors of mature gametes that commit to an oogenic or spermatogenic fate in ...

Effects of Different Chemicals on Sexual Regulation in Persimmon (Diospyros kaki Thunb.) Flowers

Frontiers in Plant Science, 2022
Research on crop sexuality is important for establishing systems for germplasm innovation and cultivating improved varieties. In this study, androecious persimmon trees were treated with various concentrations of ethrel (100, 500, and 1,000 mg/L) and ...

Dnd knockout ablates germ cells and demonstrates germ cell independent sex differentiation in Atlantic salmon

Scientific Reports, 2016
Introgression of farmed salmon escapees into wild stocks is a major threat to the genetic integrity of wild populations. Using germ cell-free fish in aquaculture may mitigate this problem.

Next‐generation proteomics improves lung cancer risk prediction

Molecular Oncology, EarlyView.
This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

Comparative Transcriptomic Analysis of Male and Female Gonads in the Zig-Zag Eel (Mastacembelus armatus)

Fishes
The zig-zag eel (Mastacembelus armatus) is a unique economic fish species in China and exhibits significant dimorphism of male and female phenotypes. Cultivating all-male seedlings can significantly improve production efficiency.

Prenatal Diagnosis of mos45,X/46,X,+mar in a Fetus With Normal Male External Genitalia and a Literature Review

Taiwanese Journal of Obstetrics & Gynecology, 2009
Objective: Prenatal diagnosis of mos45,X/46,X,+mar is difficult in genetic counseling. Patients with the presence of a Y-derived marker may manifest male or female external genitalia. Here, we report a fetus with phenotypically male external genitalia of
