Article Title: Prognostic value and experimental validation of atherosclerosis-derived pathogenic genes in colorectal cancer

doi: 10.3389/fonc.2025.1728087

Figure Lengend Snippet: Validation of the expression of 6 hub genes in CRC and AS by molecular biology experiments. (A-F) RT-qPCR validation of the differential expression of prognostic genes between normal and tumor tissues in CRC patients. (G) Western blot validation of the differential expression of 2 newly identified genes (HMMR and PALB2) between normal and tumor tissues in CRC. (H) Quantitative analysis of the relative grayscale values of Western blot bands for the 2 newly identified genes (HMMR and PALB2) in normal and tumor tissues of CRC. Data are presented as mean ± standard deviation (SD), with statistical significance indicated as * p < 0.05, *** p < 0.001, and **** p < 0.0001. ns indicates no statistical significance.

Article Title: Arginine methylation-dependent METTL14-SMN interaction regulates RNA m 6 A homeostasis

doi: 10.1038/s44319-025-00590-7

Figure Lengend Snippet: ( A ) Sanger sequencing confirmation of Mettl14 arginine methylation deficient mouse model. In total, 13 arginine resides located at the C-terminal disordered region of Mettl14 were mutated to lysine residues. ( B ) The arginine methylation levels of Mettl14 in WT, heterozygous (WT/RK), and homozygous (RK/RK) mice were detected by IP-western blot using tissue lysates from mouse spleen and thymus. ( C ) The protein expression levels of several DNA repair genes, including BRCA1, ATRIP, and PALB2, were detected by western blot using Thymus tissues from WT, WT/RK, and RK/RK mice. ( D ) Mettl14 arginine methylation deficiency increases the population of primitive hematopoietic cells (LK cells). ** P = 0.0019. ( E ) Mettl14 arginine methylation deficiency increases the population of myeloid (Mac1 + Gr1 + ) cells in the BM, but not in the spleen. * P = 0.013. ( F ) Mettl14 arginine methylation deficiency decreases the B lymphoid (B220 + ) population in the BM, but not in the spleen. * P = 0.011. ( G ) Mettl14 arginine methylation deficiency decreases the T lymphoid (CD3 + ) population in the BM, but not in the spleen. Data from three independent replicates were analyzed by Student’s t test and shown as mean ± SD. ** P = 0.0097. .
