Sine oculis homeobox 1 (Six1) is an important factor for embryonic development and carcinoma malignancy. However, the localization of Six1 varies due to protein size and cell types in different organs. In this study, we focus on the expression and localization of Six1 in male reproductive organ via bioinformatics analysis and immunofluorescent detection. The potential interacted proteins with Six1 were also predicted by protein-protein interactions (PPIs) and Enrichr analysis. Bioinformatic data from The Cancer Genome Atlas and Genotype-Tissue Expression project databases showed that SIX1 was highly expressed in normal human testis, but low expressed in the testicular germ cell tumor sample. Human Protein Atlas examination verified that SIX1 level was higher in normal than that in cancer samples.The sub-localization of SIX1 in different reproductive tissues varies but specifically in the cytoplasm and membrane in testicular cells. In mouse cells, single cell RNA-sequencing data analysis indicated that Six1 expression level was higher in mouse spermatogonial stem cells (mSSCs) and differentiating spermatogonial than in other somatic cells.Immunofluorescence staining showed the cytoplasmic localization of Six1 in mouse testis and mSSCs. Further PPIs and Enrichr examination showed the potential interaction of Six1 with bone morphogenetic protein 4 (Bmp4) and catenin Beta-1 (CtnnB1) and stem cell signal pathways. Cytoplasmic localization of Six1 in male testis and mSSCs was probably associated with stem cell related proteins Bmp4 and CtnnB1 for stem cell development.

Objective:To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on the cognition of patients with mild cognitive impairment (MCI).Methods:The PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, and VIP databases were searched for randomized controlled trials of rTMS treating MCI patients before March 2019. After screening the literature, extracting the data and two independent reviewers evaluating the quality of the included studies, the meta-analysis was conducted using version 5.3 of the RevMan software.Results:Nine studies covering 368 patients were included. The pooled results showed that compared with sham stimulation, rTMS treatment could effectively improve the cognitive ability (assessed using the Montreal instrument), episodic memory, verbal fluency and the amplitude of MCI patients′ P300 signals. P300 latency was also reduced. However, there was no significant difference, on average, in memory quotient or P300 latency between patients given rTMS plus donepezil hydrochloride and those given donepezil hydrochloride alone. Compared with the control groups, the rTMS treatment groups displayed slightly more frequent adverse reactions, mainly mild dizziness and scalp pain which disappeared within 1-2 hours without obvious residual effects.Conclusions:TMS treatment can effectively improve cognitive and memory function.
