The remarkable diversity of insect pigmentation offers a captivating avenue for studying evolution and genetics. In tephritids, understanding the molecular basis of mutant traits is also crucial for applied entomology, enabling the creation of genetic sexing strains through genome editing, thus facilitating sex-sorting before sterile insect releases. Here, we present evidence from classical and modern genetics showing that the black pupae (bp) phenotype in the GUA10 strain of Anastrepha ludens is caused by a large deletion at the ebony locus, removing the gene's entire coding region.

Patient-reported health status is an important assessment of patients with heart failure, but current approaches have substantial methodological and analytical limitations. Changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ) are commonly presented as a measure of the effect of drugs and devices, most often as the between-group difference in population means or as the odds of showing threshold changes of 5, 10, 15, and 20 points. However, the presentation of mean differences is based on statistical assumptions that are routinely violated in most trials.

Food intake is controlled by multiple converging signals: hormonal signals that provide information about energy homeostasis, but also hedonic and motivational aspects of food and food cues that can drive non-homeostatic or "hedonic" feeding. The ventral pallidum (VP) is a brain region implicated in the hedonic and motivational impact of food and foods cues, as well as consumption of rewards. Disinhibition of VP neurons has been shown to generate intense hyperphagia, or overconsumption.

Lysine demethylases (KDMs) catalyze the oxidative removal of the methyl group from histones using earth-abundant iron and the metabolite 2-oxoglutarate (2OG). KDMs have emerged as master regulators of eukaryotic gene expression and are novel drug targets; small-molecule inhibitors of KDMs are in the clinical pipeline for the treatment of human cancer. Yet, mechanistic insights into the functional heterogeneity of human KDMs are limited, necessitating the development of chemical probes for precision targeting.

Identifying genetic differences between bipolar disorder and major depression through multiple genome-wide association analyses.

Br J Psychiatry

January 2025

Center for Neurobehavioral Genetics, Semel Institute for Neuroscience and Human Behavior, David Geffen School of Medicine, University of California Los Angeles, USA; Department of Human Genetics, University of California Los Angeles, USA; and Department of Computational Medicine, University of California Los Angeles, USA.

Background: Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).

Aims: We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.
