RESUMO
OBJECTIVE: SUMO-specific protease 3 (SENP3), a member of the SUMO-specific protease family, reverses the SUMOylation of SUMO-2/3 conjugates. Dysregulation of SENP3 has been proven to be involved in the development of various tumors. However, its role in mantle cell lymphoma (MCL), a highly aggressive lymphoma, remains unclear. This study was aimed to elucidate the effect of SENP3 in MCL. METHODS: The expression of SENP3 in MCL cells and tissue samples was detected by RT-qPCR, Western blotting or immunohistochemistry. MCL cells with stable SENP3 knockdown were constructed using short hairpin RNAs. Cell proliferation was assessed by CCK-8 assay, and cell apoptosis was determined by flow cytometry. mRNA sequencing (mRNA-seq) was used to investigate the underlying mechanism of SENP3 knockdown on MCL development. A xenograft nude mouse model was established to evaluate the effect of SENP3 on MCL growth in vivo. RESULTS: SENP3 was upregulated in MCL patient samples and cells. Knockdown of SENP3 in MCL cells inhibited cell proliferation and promoted cell apoptosis. Meanwhile, the canonical Wnt signaling pathway and the expression of Wnt10a were suppressed after SENP3 knockdown. Furthermore, the growth of MCL cells in vivo was significantly inhibited after SENP3 knockdown in a xenograft nude mouse model. CONCLUSION: SENP3 participants in the development of MCL and may serve as a therapeutic target for MCL.

672 specimens of entomogenous fungi belonging to 20 species, 8 genera and 4 families were collected from 20 sampling quadrates in the Langya Mountains Nature Reserve of East Anhui. The dominant species were Beauveria bassiana, Paecilomyces farinosus, P. cateinannulatus, B. brongniartii and P. fumosoroseus, and B. bassiana was most dominant, with the relative abundance of 73.8%. The entomogenous fungi in the Reserve were high in amount but low in diversity. The amount of isolates and the abundance of each species were the highest in summer and decreased with decreasing air temperature and rainfall, while the Pielou evenness changed from relatively low to relatively high. Paecilomyces spp. had a less seasonal fluctuation of quantity than Beauveria spp.
