The retinal determination gene network (RDGN) constitutes a paradigm of a gene network controlling organ specification and growth. In this study, we probed the RDGN in the Drosophila ocelli, a set of simple eyes located on the fly's dorsal head, by studying the expression, regulation, and function of toy, hth, eya, and so, members of the Pax6, Meis, Eya, and Six gene families. Our results highlight the role of the pax6 gene toy, together with the hh signaling pathway, in the initiation of eya and so expression; the engagement of eya and so in a feedback loop necessary for their full expression; and the interplay between hh signaling and hth as a mechanism of organ size control, as general regulatory steps in the specification of visual organs.

This study utilizes single-cell RNA sequencing data to reveal the transcriptomic characteristics of breast cancer and normal epithelial cells. Nine significant cell populations were identified through stringent quality control and batch effect correction. Further classification of breast cancer epithelial cells based on the PAM50 method and clinical subtypes highlighted significant heterogeneity between triple-negative breast cancer (TNBC) and non-triple-negative breast cancer (NTNBC).

A new gene coding for an iron-containing enzyme was identified in the genome of Acinetobacter radioresistens. Bioinformatics analysis allowed the assignment of the protein to DyP peroxidases, due to the presence of conserved residues involved in heme binding and catalysis. Moreover, Ar-DyP is located in an operon coding also for other enzymes involved in iron uptake and regulation.

Around 10% of cases of primary hyperparathyroidism are thought to be genetic in origin, some of which are part of a syndromic form such as multiple endocrine neoplasia types 1, 2A or 4 or hyperparathyroidism-jaw tumor syndrome, while the remainder are cases of isolated familial primary hyperparathyroidism. Recognition of these genetic forms is important to ensure appropriate management according to the gene and type of variant involved, but screening for a genetic cause is not justified in all patients presenting primary hyperparathyroidism. The indications for genetic analysis have made it possible to propose a decision tree that takes into account whether the presentation is familial or sporadic, syndromic or isolated, patient age, and histopathological type of parathyroid lesion.

Parathyroid carcinoma is extremely rare, affecting 1% of cases of primary hyperparathyroidism. For this reason, management is poorly codified and requires expertise in specialized center. PC is genetically determined in a quarter to a third of cases, notably involving the CDC73 gene coding for parafibromin.

This study investigated the cervicovaginal microbiome's (CVM's) impact on Chlamydia trachomatis (CT) infection among Black and Hispanic adolescent and young adult women. A total of 187 women with incident CT were matched to 373 controls, and the CVM was characterized before, during, and after CT infection. The findings highlight that a specific subtype of bacterial vaginosis (BV), identified from 16S rRNA gene reads using the molBV algorithm and community state type (CST) clustering, is a significant risk factor for CT acquisition.
