Transcriptome alterations in spermatogonial stem cells exposed to bisphenol A

Abstract

Owing to their self-renewal and differentiation abilities, spermatogonial stem cells (SSCs) are essential for maintaining male fertility and species preservation through spermatogenesis. With an increase in exposure to plasticizers, the risk of endocrine-disrupting chemicals exerting mimetic effects on estrogen receptors, such as bisphenol A (BPA), has also increased. This has led to concerns regarding the preservation of male fertility. BPA impairs spermatogenesis and the maintenance of SSCs; however, the transcriptome differences caused by BPA in SSCs are poorly understood. Thus, this study aimed to investigate the transcriptome differences in SSCs exposed to BPA, using RNA sequencing (RNA-Seq) analysis. We found that cell proliferation and survival were suppressed by SSC exposure to BPA. Therefore, we investigated transcriptome differences through RNA-Seq, functional annotation, and gene set enrichment analysis. Our results showed repetitive and abundant terms related to two genes of lysosomal acidification and five genes of glycosaminoglycan degradation. Furthermore, we validated the transcriptome analyses by detecting mRNA and protein expression levels. The findings confirmed the discovery of differentially expressed genes (DEGs) and the mechanism of SSCs following exposure to BPA. Taken together, we expect that the identified DEGs and lysosomal mechanisms could provide new insights into the preservation of male fertility and related research.

NUCB2/nesfatin-1 suppresses the acrosome reaction in sperm within the mouse epididymis

“…The epididymis is a highly convoluted tubular structure adjacent to the testis and is divided into three main regions: the caput, corpus, and cauda (Sullivan et al 2019 ). Sperm produced in the testes travel through the epididymis, where they acquire motility and the ability to fertilize eggs through sperm maturation (Ahn et al 2022 ; Miyaso et al 2022 ). The epididymis plays a vital role in this process by providing an optimal environment, including essential nutrients and various molecules secreted by epithelial cells in the epididymis (Sullivan and Mieusset 2016 ).…”

Retinal transcriptome profiling identifies novel candidate genes associated with visual impairment in a mouse model of multiple sclerosis

“…Following the protocol outlined in a prior study (Ahn et al 2022 ), each sample underwent independently library preparation using 1 µg of total RNA and the Illumina TruSeq Stranded mRNA Sample Prep Kit (#RS-122-2101, Illumina, Inc., San Diego, CA, USA). In the first step, poly-A-containing mRNA molecules were purified using poly-T-attached magnetic beads.…”
