As the leading cause of disability, osteoarthritis (OA) affects people of all ages, sexes, and races. With the increasing understanding of OA, the sex differences have attracted specific attention as the burden of OA is greater in women. There is no doubt that gender-specific OA management has great potential for precision treatment. On the other hand, from the marketing aspect, a medication targeting the OA-responsive biomarker(s) shared by both genders is more favorable for drug development. Thus, in the current study, a published transcriptome dataset of knee articular cartilage was used to compare OA and healthy samples for identifying the genes with the same significantly different expression trend in both males and females. With 128 genes upregulated and 143 genes downregulated in both OA males and females, 9 KEGG pathways have been enriched based on the current knowledge, including ‘renal cell carcinoma,’ ‘ECM-receptor interaction,’ ‘HIF-1 signaling pathway,’ ‘MicroRNAs in cancer,’ ‘focal adhesion,’ ‘Relaxin signaling pathway,’ ‘breast cancer,’ ‘PI3K-Akt signaling pathway,’ and ‘human papillomavirus infection.’ Here, we explore the potential impacts of these clusters in OA. We also analyze the identified ‘cell plasma membrane related genes’ in-depth to identify the potential chondrocyte cell surface target(s) of OA management. © 2021 by the authors.
