Neurodevelopmental Defects in Human Cortical Organoids with N-Acetylneuraminic Acid Synthase Mutation

[Science Advances] Scientists found that N-acetylneuraminic acid synthase mutation resulted in the absence of both sialic acid and protein polysialylation in the cortical organoids and notably reduced the proliferation and expansion of neural progenitors.

Intestinal Paneth Cell Differentiation Relies on Asymmetric Regulation of Wnt Signaling by Daam1/2

[Science Advances] Researchers reported that the Dishevelled-associated activator of morphogenesis 1 (Daam1) and its paralogue Daam2 asymmetrically regulated canonical and noncanonical Wnt signaling.

Joint Epigenome Profiling Reveals Cell-Type-Specific Gene Regulatory Programmes in Human Cortical Organoids

[Nature Cell Biology] The authors combined a 3D genome, RNA, accessibility and methylation sequencing method with immunoFACS and RNA sequencing in cortical organoids to map the cell-type-specific regulatory landscape of human neural development across multiple epigenetic layers.

Detecting Host Responses to Microbial Stimulation Using Primary Epithelial Organoids

[Gut Microbes] Investigators derived organoids from the small intestine from a cohort of healthy individuals. Culturing intestinal epithelium on a flat laminin matrix induced their differentiation, facilitating analysis of microbial responses via the apical membrane normally exposed to the luminal content.

Reduction of Renal Interstitial Fibrosis by Targeting Tie2 in Vascular Endothelial Cells

[Pediatric Research] Investigators evaluated the effects of an agonistic Tie2 signal on renal interstitial fibrosis and elucidated the underlying mechanisms.

EEF1A2 Promotes HIF1A Mediated Breast Cancer Angiogenesis in Normoxia and Participates in a Positive Feedback Loop With HIF1A in Hypoxia

[British Journal Of Cancer] Higher EEF1A2 levels in breast cancer cells enhanced cell growth, movement, blood vessel function, and tubule formation in HUVECs, as confirmed by ex-ovo and in-vivo tests.
