GENDER ASSIGNMENT IN COMPLETE ANDROGEN INSENSITIVITY SYNDROME. WHO SHOULD BE THE DECISION MAKER

open access: yesPakistan Armed Forces Medical Journal, 2020
Androgen insensitivity syndrome (AIS) is a condition in which the target cells are unable to respond to androgenic hormones. This inability can be complete or partial.

Y chromosome functions in mammalian spermatogenesis

open access: yeseLife, 2021
The mammalian Y chromosome is critical for male sex determination and spermatogenesis. However, linking each Y gene to specific aspects of male reproduction has been challenging.

Characterization of the Arachis (Leguminosae) D genome using fluorescence in situ hybridization (FISH) chromosome markers and total genome DNA hybridization [PDF]

open access: yes, 2008
Chromosome markers were developed for Arachis glandulifera using fluorescence in situ hybridization (FISH) of the 5S and 45S rRNA genes and heterochromatic 4'-6-diamidino-2-phenylindole (DAPI) positive bands.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

Morphological detection of X- and Y-chromosomes in smears and paraffin-embedded tissues using a non-isotopic in situ hybridization technique (NISH) [PDF]

open access: yes, 1994
Pharyngeal smears and paraffin-embedded tissue specimens (skeletal muscle, kidney) obtained from 10 male and 10 female individuals were evaluated using non-isotopic in situ hybridization (NISH) with commercial X- and Y-specific biotinylated probes which ...

Rad27/FEN1 prevents accumulation of Okazaki fragments and ribosomal DNA copy number changes

open access: yesFEBS Letters, EarlyView.
The budding yeast Rad27 is a structure‐specific endonuclease. Here, the authors reveal that Rad27 is crucial for maintaining the stability of the ribosomal RNA gene (rDNA) region. Rad27 deficiency leads to the accumulation of Okazaki fragments and changes in rDNA copy number.

The Y chromosome: a blueprint for men’s health?

open access: yesEuropean Journal of Human Genetics, 2017
The Y chromosome has long been considered a ‘genetic wasteland’ on a trajectory to completely disappear from the human genome. The perception of its physiological function was restricted to sex determination and spermatogenesis.

Complex Evolutionary History of the Y Chromosome in Flies of the Drosophila obscura Species Group. [PDF]

open access: yes, 2020
The Drosophila obscura species group shows dramatic variation in karyotype, including transitions among sex chromosomes. Members of the affinis and pseudoobscura subgroups contain a neo-X chromosome (a fusion of the X with an autosome), and ancestral Y ...

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...
