Gonadal soma-derived factor (gsdf) has been demonstrated to be essential for testicular differentiation in medaka (Oryzias latipes). To understand the protein dynamics of Gsdf in spermatogenesis regulation, we used a His-tag "pull-down" assay coupled with shotgun LC-MS/MS to identify a group of potential interacting partners for Gsdf, which included cytoplasmic dynein light chain 2, eukaryotic polypeptide elongation factor 1 alpha (eEF1α), and actin filaments in mature medaka testis. As for the interaction with TGFβ-dynein being critical for spermatogonial division in Drosophila melanogaster, the physical interactions of Gsdf-dynein and Gsdf-eEF1α were identified through a yeast 2-hybrid (Y2H) screening of an adult testis cDNA library using Gsdf as bait, which were verified by a paired Y2H assay. Co-immunoprecipitation of Gsdf and eEF1α was defined in adult testes as supporting the requirement of a Gsdf and eEF1α interaction in testis development. Proteomics analysis (data are available via ProteomeXchange with identifier PXD022153) and ultrastrutural observations showed that Gsdf deficiency activated eEF1α-mediated protein synthesis and ribosomal biogenesis, which in turn led to the differentiation of undifferentiated germ cells. Thus, our results provide a framework and new insight into the coordination of a Gsdf (TGFβ and eEF1α complex in the basic processes of germ cell proliferation, transcriptional and translational control of sexual RNA which may be fundamentally conserved across phyla during sexual differentiation.

A showcase of a selection of the Black Cultural Archives photo exhibition of up-and-coming Black British leaders.

Chatham House is pleased to showcase a selection of the Black Cultural Archives photo exhibition of up-and-coming Black British leaders. These portraits illuminate the talent and pipeline of ‘next gen’ leaders in the Black British community – some of whom will be in attendance at the reception. The chair of the Black British Cultural Archives, Dr Yvonne Thompson, will make short remarks at around 18:20 BST.

We hope you will join your fellow members and Chatham House staff for a chance to connect and celebrate.

You are welcome to attend the event Black perspectives on International Relations preceding the reception.

Please note as space is limited, this event is operating a ballot for registrations. Your place will be confirmed by Tuesday 25 October if you are successful.

Hear from the innovative leaders and companies driving change towards a more sustainable future.

This event is an opportunity to hear from the innovative leaders and companies driving change towards a more sustainable future.

The evening begins with a panel discussion then, over sustainably sourced drinks and canapés, you are invited to walk through Chatham House and explore the innovative and experimental ideas enabling radical shifts to allow us to prosper without exhausting our planet’s resources.

Our exhibiting partners include Earthshot Prize winner NotPla, Hawkins Brown, Polymateria, and BEEN London. 

Bronwen Maddox, director of Chatham House, opens the evening at 6pm and introduces our panel of experts, chaired by Ana Yang, head of Chatham House’s Sustainability Accelerator. 

Please note that this event is operating a ballot for in-person attendance. Your place will be confirmed by Wednesday 12 April if you are successful.

Hyperbilirubinemia (HB) is a key risk factor for hearing loss in neonates, particularly premature infants. Here, we report that bilirubin (BIL)-dependent cell death in the auditory brainstem of neonatal mice of both sexes is significantly attenuated by ZD7288, a blocker for hyperpolarization-activated cyclic nucleotide-gated (HCN) channel-mediated current (I_h), or by genetic deletion of HCN1. GABAergic inhibitory interneurons predominantly express HCN1, on which BIL selectively acts to increase their intrinsic excitability and mortality by enhancing HCN1 activity and Ca²⁺-dependent membrane targeting. Chronic BIL elevation in neonatal mice in vivo increases the fraction of spontaneously active interneurons and their firing frequency, I_h, and death, compromising audition at the young adult stage in HCN1^+/+, but not in HCN1^–/– genotype. We conclude that HB preferentially targets HCN1 to injure inhibitory interneurons, fueling a feedforward loop in which lessening inhibition cascades hyperexcitability, Ca²⁺ overload, neuronal death, and auditory impairments. These findings rationalize HCN1 as a potential target for managing HB encephalopathy.

Impaired inhibitory synapse development is suggested to drive neuronal hyperactivity in autism spectrum disorders (ASD) and epilepsy. We propose a novel mechanism by which astrocytes control the development of parvalbumin (PV)-specific inhibitory synapses in the hippocampus, implicating ephrin-B/EphB signaling. Here, we utilize genetic approaches to assess functional and structural connectivity between PV and pyramidal cells (PCs) through whole-cell patch–clamp electrophysiology, optogenetics, immunohistochemical analysis, and behaviors in male and female mice. While inhibitory synapse development is adversely affected by PV-specific expression of EphB2, a strong candidate ASD risk gene, astrocytic ephrin-B1 facilitates PV->PC connectivity through a mechanism involving EphB signaling in PV boutons. In contrast, the loss of astrocytic ephrin-B1 reduces PV->PC connectivity and inhibition, resulting in increased seizure susceptibility and an ASD-like phenotype. Our findings underscore the crucial role of astrocytes in regulating inhibitory circuit development and discover a new role of EphB2 receptors in PV-specific inhibitory synapse development.
