Article Title: Lysine malonylation regulates human sperm motility

doi: 10.1038/s42003-026-09683-y

Figure Lengend Snippet: A The Kmal in total proteins of (TP) and protein fractions of the mitochondrion (Mit), head, and cytoplasm (Cyt) isolated from human sperm were examined by Western blot. The specificity of cellular components was validated by Western blot using the corresponding markers: PRM2 for sperm head, COX6B1 for mitochondrion, and ACTIN for cytoplasm. The proteins for Western blot were shown in the coomassie brilliant blue (CBB) staining image. B , C The localization of malonylated proteins within human sperm was investigated by immunofluorescence assay via laser scanning confocal microscopy (LSCM, ( B )) and super-resolution structured illumination microscopy (SIM, ( C )). All the experiments were conducted with samples from 8 normozoospermic men. The scale bar represents 5 μm.

doi: 10.1016/j.omtn.2017.09.007

Figure Lengend Snippet: Morphological and Phenotypic Characterization of Freshly Isolated Human Spermatogonia, Pachytene Spermatocytes, and Round Spermatids (A–C) Phase-contrast microscope revealed the morphology of the freshly isolated human pachytene spermatocytes (A), spermatogonia (B), and round spermatids (C) of OA patients. (D–F) DIC microscope showed the morphological characteristics of the freshly isolated human pachytene spermatocytes (D), spermatogonia (E), and round spermatids (F) of OA patients. Scale bars, 20 μm (A–C) and 5 μm (D–F). (G) RT-PCR revealed the transcripts of GPR125 , RET , GFRA1 , THY1 , UCHL1 , MAGEA4 , and PLZF in the fleshly isolated spermatogonia, the expression of SYCP3 and SYCP1 in pachytene spermatocytes, and mRNA of TNP1 , TNP2 , PRM1 , PRM2 , and ACR in round spermatids. RNA without RT (RT-) but with PCR of GAPDH primers was utilized as negative controls, and GAPDH served as loading controls of total RNA.
