Transcriptional enhanced associate domain (TEAD) transcription factors play important roles in embryonic stem cell (ESC) renewal and differentiation. Four TEAD transcription factors (Tead1, Tead2, Tead3 and Tead4) and their various splice variants have been discovered in mice, but the expression pattern of them during pluripotency state transition is unclear. Here, we investigated the expression of TEADs and their splice variants in mouse ESCs at different pluripotent/differentiating states and adult mouse tissues. Our results preliminarily revealed the diversity and heterogeneity of TEAD family, which is helpful for understanding their overlapping and distinctive functions. Furthermore, a novel splice variant of Tead1 was identified and named Tead1 isoform 4.

Poultry egg production is shaped by the intertwined action of multiple physiological systems, greatly magnifying the complexity of its underlying genetic regulation. Although multitissue mapping of regulatory variants offers a powerful route to untangle this complexity, comprehensive data sets in ducks remain scarce. Meanwhile, the contributions of peripheral systems beyond neuroendocrine regulation on poultry egg production are still largely unexplored.

Nonsense-mediated mRNA decay (NMD) is a conserved RNA surveillance mechanism that degrades transcripts with premature termination codons (PTCs) and finetunes gene expression by targeting RNA transcripts with other NMD inducing features. This study demonstrates that conditional knockout of , a key NMD component, in oligodendrocyte lineage cells disrupts the degradation of PTC-containing transcripts, including aberrant variants of the RNA-binding protein The loss of SMG5 in both sexes of mice impaired oligodendrocyte differentiation, reduced myelin gene expression, and led to thinner myelin sheaths and compromised motor function in mice. Mechanistically, HNRNPL was shown to regulate the alternative splicing of myelin-associated genes and , and promote oligodendrocyte differentiation.

Purpose: Advancements in sequencing technologies have significantly improved clinical genetic testing, yet the diagnostic yield remains around 30-40%. Emerging technologies are now being deployed to address the remaining diagnostic gap.
Methods: We tested whether short-read genome sequencing could increase the diagnostic yield in individuals enrolled into the UCI-GREGoR research study, who had suspected Mendelian conditions and prior inconclusive testing.

Small-cell lung cancer (SCLC), an aggressive neuroendocrine tumor strongly associated with exposure to tobacco carcinogens, is characterized by early dissemination and dismal prognosis with a five-year overall survival of less than 7%. High-frequency gain-of-function mutations in oncogenes are rarely reported, and intratumor heterogeneity (ITH) remains to be determined in SCLC. Here, via multiomics analyses of 314 SCLCs, we found that the ASCL1/MKI67 and ASCL1/CRIP2 clusters accounted for 74.

Microtubule-actin cross-linking factor 1 (MACF1) is a large protein of the spectraplakin family, which is essential for brain development. MACF1 interacts with microtubules through the growth arrest-specific 2 (Gas2)-related (GAR) domain. Heterozygous MACF1 missense variants affecting the zinc-binding residues in this domain result in a distinctive cortical and brain stem malformation.
