Unlabelled: The past decade has seen remarkable progress in identifying genes that, when impacted by deleterious coding variation, confer high risk for autism spectrum disorder (ASD), intellectual disability, and other developmental disorders. However, most underlying gene discovery efforts have focused on individuals of European ancestry, limiting insights into genetic risks across diverse populations. To help address this, the Genomics of Autism in Latin American Ancestries Consortium (GALA) was formed, presenting here the largest sequencing study of ASD in Latin American individuals (n>15,000).

Single-cell RNA sequencing (scRNA-seq) has revolutionized cell biology by enabling the profiling of transcriptomes at a single-cell resolution, leading to important discoveries that have advanced our understanding of cellular and tissue heterogeneity, developmental trajectories, and disease progression. Despite these important advances, scRNA-seq is limited to measuring the transcriptome providing a partial view of cellular function. To address this limitation, multimodal scRNA-seq assays have emerged, allowing for the simultaneous measurement of RNA expression and protein.

Phelan-McDermid syndrome (PMS) is a neurodevelopmental disorder caused by haploinsufficiency of the SHANK3 gene. Approximately 25% of individuals with PMS have epilepsy. Treatment of epilepsy in PMS may require multiple anticonvulsants, and in a minority of cases, seizures remain poorly controlled.

Stem cells are the foundation for cell therapy due to their ability to self-renew, differentiate into other cell types, and persist throughout the life of an organism. Stem cell isolation and transplantation have not yet been established in Hexacorallia, a cnidarian subclass containing stony corals and sea anemones. Here, we demonstrate that candidate stem cells in the hexacorallian Nematostella vectensis can be transplanted into adult animals.

Background: Pembrolizumab plus chemotherapy provides clinically meaningful benefit as first-line therapy for advanced (locoregional extension and residual disease after surgery)/metastatic/recurrent mismatch repair-proficient (pMMR) and mismatch repair-deficient (dMMR) endometrial cancer, with greater magnitude of benefit in the dMMR phenotype. We evaluated the addition of pembrolizumab to adjuvant chemotherapy (with/without radiation therapy) among patients with newly diagnosed, high-risk endometrial cancer without any residual macroscopic disease following curative-intent surgery.

Methods: We included patients with histologically confirmed high-risk [International Federation of Gynecology and Obstetrics (FIGO) stage I/II of non-endometrioid histology or endometrioid histology with p53/TP53 abnormality, or stage III/IVA of any histology] endometrial cancer following surgery with curative intent and no evidence of disease postoperatively, with no prior radiotherapy or systemic therapy.

Article Synopsis
  • - Phelan-McDermid syndrome (PMS) is a rare genetic disorder linked to the loss of the SHANK3 gene, and while many of its clinical features are known, cardiovascular issues, particularly aortic root dilation (ARD), are less explored.
  • - A study of 59 PMS participants aimed to determine the prevalence of ARD and its potential links to specific genetic variations, particularly focusing on the size of deletions on chromosome 22.
  • - Findings revealed that 14% of participants had ARD, with a statistically significant association between larger chromosome 22 deletions and an increased incidence of ARD, indicating that genetic factors may help identify those at higher risk.

Requiem sharks (genus Carcharhinus) have previously been reported to form large aggregations around marine infrastructures in the eastern Mediterranean Sea. While this behaviour may offer fitness advantages at the individual level, the implications of extended residency at human-altered habitats for population persistence have yet to be assessed. In this work, we investigated the phylogeographic and demographic composition of sharks near a coal-fired power and desalination station in Israel.

Article Synopsis
  • The study aimed to assess the safety and tolerability of an individualized starting dose (ISD) of niraparib in patients with newly diagnosed advanced ovarian cancer who responded to platinum-based chemotherapy.
  • An analysis of treatment-emergent adverse events (TEAEs) revealed that common side effects occurred early, with hematologic TEAEs resolving in over 89% of patients within a median duration of about 2 weeks.
  • Overall, the niraparib ISD was found to be well tolerated, indicating the importance of close monitoring after starting treatment and helping set patient expectations regarding safety.

The germ cell-less gene is crucial for gonad development in various organisms. Early interventions in its expression suggested a regulatory role at the mitotic stages of spermatogenesis, and its early knockout resulted in complete sterility in Drosophila. Genomic and transcriptomic data available for the catadromous giant prawn Macrobrachium rosenbergii enabled the identification of a germ cell-less homolog for this species, which we termed MroGCL (mRNA accession number OQ533056).
