Data normalization was performed by dividing each microarray data set by its median value. Oligodendrocyte-related probe sets were chosen based on previous DNA microarray reports and literature search. Among the 37 oligodendrocyte-related genes we probed for, probe sets for 11 genes were called as absence by MAS5 in our experiments. They were CLDN11, EGR2, ERBB2, ERBB4, MMP9, MPZ, MYT2, PAX3, PMP2, POU3F1, and NRG2. Mann-Whitney U-test was employed to identify differentially expressed probe sets. In cases where multiple probe sets were found in one gene, we chose the one showing the lowest P value..

However, predictive molecular marker profiles for risk stratification and therapy optimization are not yet available for routine clinical assessment. Methods and Findings: Using tissue microarrays, we retrospectively analyzed samples from 364 patients with primary MM. We investigated a panel of 70 immunohistochemical (IHC) antibodies for cell cycle, apoptosis, DNA mismatch repair, differentiation, proliferation, cell adhesion, signaling and metabolism. A marker selection procedure based on univariate Cox regression and multiple testing correction was employed to correlate the IHC expression data with the clinical follow-up (overall and recurrence-free survival).

Platelet-Derived Microparticles Enhance Megakaryocyte Differentiation and Platelet Generation Via Mir-1915-3P
ARTICLE https://doi.org/10.1038/s41467-020-18802-0 OPEN Platelet-derived microparticles enhance megakaryocyte differentiation and platelet generation via miR-1915-3p Mingyi Qu 1,2,3, Xiaojing Zou1, Fang Fang1,2,3, Shouye Wang1,3, Lei Xu1,3, Quan Zeng1,3, Zeng Fan1,3, Lin Chen1,3, ✉ ✉ Wen Yue1,3, Xiaoyan Xie 1,3 & Xuetao Pei1,3 1234567890():,; Thrombosis leads to platelet activation and subsequent degradation; therefore, replenishment of platelets from hematopoietic stem/progenitor cells (HSPCs) is needed to maintain the physiological level of circulating platelets. Platelet-derived microparticles (PMPs) are protein- and RNA-containing vesicles released from activated platelets. We hypothesized that factors carried by PMPs might inﬂuence the production of platelets from HSPCs, in a positive feedback fashion. Here we show that, during mouse acute liver injury, the density of megakaryocyte in the bone marrow increases following an increase in circulating PMPs, but without thrombopoietin (TPO) upregulation. In vitro, PMPs are internalized by HSPCs and drive them toward a megakaryocytic fate. Mechanistically, miR-1915-3p, a miRNA highly enriched in PMPs, is transported to target cells and suppresses the expression levels of Rho GTPase family member B, thereby inducing megakaryopoiesis. In addition, direct injection of PMPs into irradiated mice increases the number of megakaryocytes and platelets without affecting TPO levels. In conclusion, our data reveal that PMPs have a role in promoting megakaryocytic differentiation and platelet production. 1 Stem Cells and Regenerative Medicine Lab, Institute of Health Service and Transfusion Medicine Beijing, Beijing 100850, China. 2 Beijing Institute of Radiation Medicine, Beijing 100850, China. 3 South China Research Center for Stem Cell & Regenerative Medicine, SCIB, Guangzhou 510005, China.
