Objective To investigate the effects of terahertz(THz)radiation on mouse testicular tissue and its potential molecular mechanisms.Methods A total of 125 male C57BL/6J mice(6~8 weeks old)were randomly divided into control group and low-,medium-and high-radiation power groups.The mice of the latter 3 groups were exposed to THz radiation at a frequency of 2.5 T,with an average power density of 38,115,or 318 mW/cm2,for 5 or 10 min.The detection time was immediately or 24 h after exposure.HE staining was used to observe pathological damage.ELISA was employed to detect the expression of inflammatory factors in testicular tissue.RNA-seq was utilized to detect the global changes of gene expression.The differentially expressed genes(DEGs)were screened and bioinformatics was used to cluster them.The screened genes were further analyzed with RT-qPCR to determine the time-dependent and dose-dependent relationships of the expression with THz exposure.Finally,sperm quality was evaluated morphologically using a microscope.Results Three doses of THz radiation exposure did not cause significant pathological damages to mouse testicular tissue.TNF-α expression was increased immediately after exposure at average power density of 115 mW/cm2(P<0.01),and the expression of IL-1β and TNF-α were both increased when the dose reached 318 mW/cm2(P<0.01).However,all the 3 factors returned to normal levels in 24 h after exposure.RNA-seq results showed that THz radiation exposure caused abnormal expression of 56 genes.Cluster analysis indicated that these DEGs were mainly enriched in immune and inflammatory responses,enzyme activity,sperm development and capacitation functions.Then for 5 selected key genes,Crisp1,Adam7,Ltf,Rnase9,and Bsph1,the expression of Crisp1 and Rnase9 was decreased immediately after exposure to 115 mW/cm2 THz radiation,the dose of 318 mW/cm2 resulted in obvious changes in the expression of the 5 genes(P<0.05),and their expression returned to normal levels in 24 h after exposure.Morphological observation displayed that exposure to all the 3 doses of THz had no influence on sperm quality.Conclusion THz radiation exposure causes temporary inflammatory response in testicular tissue and abnormal expression of sperm functions-related genes.However,these changes return to normal 24 h after exposure,and additionally,do not impair sperm quality.

Objective To observe the dynamic changes of cardiac lymphangiogenesis in Doxorubicin(DOX)-induced dilated cardiomyopathy(DCM)model mice,and to study the the protective mechanism of Kuoxin Decoction.Methods The DCM mouse model was established by intraperitoneal injection of DOX,and the dynamic observation was performed every week.On this basis,60 C57BL/6 mice were randomly divided into 6 groups(n=10):control group,Model group,L-KXD,M-KXD and H-KXD groups and Captopril group.After successful modeling,the KXD and the positive control drug Captopril were administered continuously for 28 days.Echocardiography was used to detect cardiac function in mice,HE staining and Masson staining were used to observe pathological and morphological changes of the heart,Whole-mount immunofluorescent staining was used to detect the expression of LYVE-1 and Podoplanin in epicardial lymphatic vessels,Western blot was used to detect the expression of VEGFR-3 protein,and qPCR was used to detect the expression of VEGFR-3 mRNA.Results DCM mice induced by DOX showed significant cardiac function decline from the third week(DOX:15 mg·kg-1,P<0.05),and significant ventricular remodeling at the fifth week(DOX:15 mg·kg-1,P<0.01);The lymphatic vessel area of the mouse heart decreased significantly from the fourth week(DOX:20 mg·kg-1,P<0.0001),and the expression of VEGFR-3 decreased significantly from the third week(DOX:15 mg·kg-1,P<0.01).Conclusion KXD can improve ventricular remodeling and cardiac function in DOX-induced DCM mice,promote cardiac lymphangiogenesis,and upregulate the expression of VEGFR-3 at protein and mRNA levels,with a better effect than captopril.DOX-induced cardiac lymphangiogenesis in DCM mice leads to severe myocardial fibrosis and weakened cardiac function,which gradually worsens with the accumulation of modeling time and dose.KXD can promote cardiac lymphangiogenesis and improve cardiac function in DOX-induced DCM mice.The mechanism may be related to the up-regulation of VEGFR-3 expression.

【Objective】 To investigate the effects of the loss of exon 1 of TFE3 on nuclear localization of chimeric TFE3 protein in TFE3 translocation renal cell carcinoma (TFE3 tRCC). 【Methods】 The localization of TFE3 protein in TFE3 tRCC and clear cell renal cell carcinoma (ccRCC) were detected with immunochemistry. The exon retention of TFE3 gene in TFE3 tRCC was analyzed in databases and literatures. The plasmids containing TFE3 full-length and different-length of TFE3 exons which were constructed to pCDH-MCS-EGFP-Puro were transfected into HEK293T using Lipo FiterTM. The localization of EGFP protein in HEK293T cells were detected with confocal microscopy. The localization of TFE3 protein and truncated TFE3 protein were detected with Western blotting. The mRNA expression of the downstream genes of TFE3 protein were detected with q-PCR. 【Results】 Strong nuclear signal of TFE3 protein was observed in TFE3 tRCC, whereas TFE3 protein in ccRCC was mainly localized in cytoplasm. The results of fluorescence imaging and Western blotting showed that TFE3 full-length protein was expressed both in nucleus and cytoplasm, and the expression of truncated TFE3 protein was mainly localized in nucleus. The q-PCR analysis demonstrated that the deletion of exon 1 in TFE3 gene led to a higher transcriptional level of targeted genes of TFE3 protein. 【Conclusion】 The loss of exon 1 in TFE3 played a critical role in preventing TFE3 protein from entering the nucleus. In TFE3 tRCC, the loss of exon 1 in TFE3 gene leads to the nuclear localization of TFE3 fusion protein and activation of its downstream target genes. This mechanism promises to uncover the occurrence and development of TFE3 tRCC.
