Figure Lengend Snippet: Cell selection using automated magnetic cell sorting (A) Cells were stained with CD45-biotin and CD31-biotin and sorted using autoMACS® Pro Separator. (B) Number of cells before staining for autoMACS® separation (step 11), and number of cells recovered from positive selection (CD45 + and CD31 + cells) and negative selection (CD45 - and CD31 - cells) in step 23. Each dot represents combined numbers from inguinal, axillary and brachial lymph nodes from 6 mice. Colors indicate biological replicates. (C) Percentages of cells after separation compared to the pre-staining cell count performed in step 11. (D) Purity check of separated cells using flow cytometry and staining for CD45 and CD31. (E) Overlay plots of positive selection (blue) and negative selection (red). (F) Percentage of CD45 + , CD45 - and CD31 + cells recovered (∗∗∗∗ p value < 0.0001, ∗ p value < 0.05). (G) Final viability check of positive and negative selected cells acquired just before performing scRNA-sequencing analysis.

Article Title: A mechanism of target mRNA selection and activity regulation in meiosis-related RBM46-MEIOC-YTHDC2 complex

doi: 10.1016/j.isci.2026.116234

Figure Lengend Snippet: XRN2 is a new partner of MEIOC and involved in RMY-dependent RNA repression (A) Immunoprecipitated MEIOC complexes were separated by SDS-PAGE and the protein in the gel was stained with silver prior to mass spectrometry (MS). (B) Related proteins in MEIOC complex were identified by MS. (C) Cytoplasm and nuclei were separated from HEK293T cells transfected with MEIOC and YTHDC2 (M + Y). Lamin B1 was used as a nuclear marker and GADPH as a cytoplasmic marker, N = 3. (D) XRN2 protein was co-immunoprecipitated with MEIOC. IgG was used as a negative control. N = 3. (E) Western blot analysis of MEIOC and XNR2 protein. A lentivirus containing HIS-MEIOC infected HEK293T cells. The cells were lysed with RIPA buffer and then coIP assay was performed with anti-XRN2 antibody. IgG was used as a negative control. N = 3. (F) Western blot analysis of XRN2 and β-Actin from HEK293T cells transfected with XRN2 siRNAs and control siRNA, N = 3. (G) RT-qPCR analysis showing relative mRNA levels of XRN2 in HEK293T cells transfected with XRN2 siRNAs and control siRNA, N = 3. (H) Relative luciferase activities of F-Luc-Rad21 3′UTR in HEK293T cells after knockdown of XRN2 only or combined with the expression of RBM46, MEIOC and YTHDC2 (RMY). N = 3. Data are presented as mean ± SEM. p values were determined by unpaired t test with Welch’s correction (C–E) or by one-way ANOVA with Benjamini-Hochberg correction (F–H). (I) A model of RMY complex assembly and target mRNA degradation.
