The evolution of chromosomal sex determination and dosage compensation
In many species, sex is determined by a system based on X and Y chromosomes, the latter having lost much of their genetic activity. Y chromosomes have evolved independently many times, and the associated change in gene dosage in the heterogametic (XY ...

Despite frogs avoiding low temperatures, examination of four salamander species revealed that none avoided cold and all possessed cold tolerance. Functional analysis of TRPM8, a cold sensor, showed that all salamander TRPM8s had lost their cold sensitivity.

Modeling Down Syndrome Neurodevelopment with Dosage Compensation
Due to their underlying genetic complexity, chromosomal disorders such as Down syndrome (DS), which is caused by trisomy 21, have long been understudied and continue to lack effective treatments.

Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Relationships between cell cycle regulator gene copy numbers and protein expression levels in Schizosaccharomyces pombe. [PDF]
We previously determined the copy number limits of overexpression for cell division cycle (cdc) regulatory genes in the fission yeast Schizosaccharomyces pombe using the "genetic tug-of-war" (gTOW) method.

Evolutionary Comparison of X-Chromosome Dosage Compensation Across Caenorhabditis Species [PDF]
Many species determine sex by assessing sex-chromosome dose. In flies, mammals, and nematodes, males have one X chromosome and females or hermaphrodites have two.

Clustering Algorithm Reveals Dopamine‐Motor Mismatch in Cognitively Preserved Parkinson's Disease
ABSTRACT Objective To explore the relationship between dopaminergic denervation and motor impairment in two de novo Parkinson's disease (PD) cohorts. Methods n = 249 PD patients from Parkinson's Progression Markers Initiative (PPMI) and n = 84 from an external clinical cohort.

Theoretical and empirical comparisons of expected and realized relationships for the X-chromosome
Background X-chromosomal loci present different inheritance patterns compared to autosomal loci and must be modeled accordingly. Sexual chromosomes are not systematically considered in whole-genome relationship matrices although rules based on ...

Efficacy of Inebilizumab in N‐MOmentum Trial Participants With or Without Prior Immunosuppressants
ABSTRACT This post hoc analysis examined the impact of prior immunosuppressants on the long‐term efficacy and safety of inebilizumab, a cluster of differentiation 19+ B‐cell–depleting monoclonal antibody, in participants with aquaporin‐4–seropositive neuromyelitis optica spectrum disorder from the N‐MOmentum trial (NTC02200770).
