Alternative splicing is essential for the generation of various protein isoforms that are involved in cell differentiation and tissue development. In addition to internal coding exons, alternative splicing affects the exons with translation initiation codons; however, little is known about these exons. Here, we performed a systematic classification of human alternative exons using coding information.

Article Synopsis
  • Group B streptococcus (GBS) is a significant cause of infections in neonates and pregnant women, with Japan implementing guidelines for screening and antibiotic use, yet infections have not decreased significantly.
  • Approximately 15% of pregnant women lack GBS screening, and issues like intermittent colonization lead to early-onset disease; current preventative measures don't address increasing cases of late-onset disease.
  • This study found that using polymerase chain reaction for GBS detection was more effective than culture methods, highlighted the risk of horizontal transmission, and emphasized the need for better diagnostic tools and potential maternal vaccination for prevention.

Background: Leukocytes are induced to migrate into the uterus at parturition, releasing cytokines and chemokines that activate it for delivery. A specific chemotactic signal is required for these actions, and published evidence suggests that it comes from the human fetal membranes and has a time-dependent component (ie, cells obtained at term in labor migrate more than cells obtained at term not yet in labor). The hypothesis that the fetal membrane chemoattractants activate the leukocytes to become responsive for migration was tested.

Article Synopsis
  • - The study investigates the organized structure of the eukaryotic nucleus and the role of RNA-binding proteins (RBPs) in forming meshworks that aid in RNA splicing, though the nuclear architecture facilitating this process was previously unclear.
  • - It identifies two distinct types of RBP meshworks within the nucleus, which are formed through mutual exclusion dynamics between charged and uncharged regions of the RBPs, suggesting a competitive relationship in occupying space on pre-mRNA for splicing.
  • - The research also highlights that optical enhancement of these meshworks leads to abnormal splicing patterns related to neurodegenerative gene functions, and links genetic mutations found in neurodegenerative diseases to impaired meshwork formation in cells.

Background: Left ventricular (LV) structural and functional changes have been reported in patients with aortic stenosis (AS) who have undergone transcatheter aortic valve implantation (TAVI); however, the relationship between change in LV structure and systolic function and tissue characteristics assessed via cardiovascular magnetic resonance imaging (CMRI) post-TAVI has been not fully elucidated. This study aimed to investigate this relationship in patients with severe AS who underwent TAVI and CMRI.

Methods: In this retrospective study, 65 patients who underwent TAVI and CMRI at the 6-month follow-up were analyzed.

Article Synopsis
  • Ahed is a newly identified gene in haematopoiesis that plays a crucial role in blood cell development, discovered through screening mutant embryonic stem cells.
  • Conditional knockout of Ahed leads to severe anemia and prenatal death, as its absence hampers the ability of haematopoietic cells to regenerate in living organisms.
  • Deletion of Ahed disrupts multiple biological pathways in adult mice and is linked to mutations found in cancer patients, highlighting its importance in both normal blood development and potential involvement in cancers.

Pathogenic variants in GFPT1, encoding a key enzyme to synthesize UDP-N-acetylglucosamine (UDP-GlcNAc), cause congenital myasthenic syndrome (CMS). We made a knock-in (KI) mouse model carrying a frameshift variant in Gfpt1 exon 9, simulating that found in a patient with CMS. As Gfpt1 exon 9 is exclusively expressed in striated muscles, Gfpt1-KI mice were deficient for Gfpt1 only in skeletal muscles.
