Oncogenic BRAF, Unrestrained by TGFβ-Receptor Signaling, Drives Right-Sided Colonic Tumorigenesis

The proximal colonic tumors that developed in a mouse model of right-sided colon cancer exhibited a fetal-like progenitor phenotype (Ly6a/Sca1+) and lacked expression of Lgr5 and its associated intestinal stem cell signature.

Role of Cytoplasmic Localization of Maspin in Promoting Cell Invasion in Breast Cancer with Aggressive Phenotype

Scientists studied the biological function of cytoplasmic maspin in breast cancer cell lines. Subcellular localization of maspin in MDA-MB-231 breast cancer cells was mainly detected in the cytoplasm, whereas in MCF10A mammary epithelial cells, maspin was present in both cytoplasm and nucleus.

Transcriptome Analysis of MBD5-Associated Neurodevelopmental Disorder (MAND) Neural Progenitor Cells Reveals Dysregulation of Autism-Associated Genes

Researchers created neural progenitor cells (NPC) derived from individuals with chromosome 2q23.1 deletion and conducted RNA-seq to identify differentially expressed genes (DEGs) and the biological processes and pathways altered in MAND.

Acute Myeloid Leukemia-Induced Functional Inhibition of Healthy CD34+ Hematopoietic Stem and Progenitor Cells

Scientists exposed healthy bone marrow-derived CD34+ hematopoietic stem and progenitor cells (HSPC) to cell-free supernatants derived from acute myeloid leukemia (AML) cell lines to examine proliferation, cell cycling, colony formation, and differentiation of healthy CD34+ HSPC.

Platelets Orchestrate the Resolution of Pulmonary Inflammation in Mice by T Reg Cell Repositioning and Macrophage Education

Investigators demonstrated that platelets were recruited into the lung together with neutrophils during the onset of inflammation and alongside Treg cells during the resolution phase.

Interplay between Transforming Growth Factor-β and Nur77 in Dual Regulations of Inhibitor of Differentiation 1 for Colonic Tumorigenesis

The authors showed that Nur77 enhanced TGFβ/Smad3-induced ID1 mRNA expression through hindering Smurf2-mediated Smad3 mono-ubiquitylation, resulting in ID1 upregulation.

The Hepatokine Fetuin-A Disrupts Functional Maturation of Pancreatic Beta Cells

The effects of fetuin-A were assessed during in vitro maturation of porcine neonatal islet cell clusters and in adult human islets. Expression alterations were examined via microarray, RNA sequencing and reverse transcription quantitative real-time PCR, proteins were analyzed by western blotting and immunostaining, and insulin secretion was quantified in static incubations.
