AIM:This study aims to investigate the functions of interleukin-6(IL-6)/Janus kinase 2(JAK2)/signal transducer and activator of transcription 3(STAT3)signaling pathway in adenomyosis(ADM),and to assess the therapeutic potential of JAK2 inhibitor AG490.METHODS:(1)Neonatal female mice were randomly divided into 2 groups:control group and ADM group.An ADM mice model was established by tamoxifen.Additionally,Western blot was employed to detect the expression of IL-6/JAK2/STAT3 signaling pathway-related proteins.(2)Human endometrial adenocarcinoma Ishikawa cells were treated with AG490,and Western blot was performed to evaluate the expression of the proteins related to IL-6/JAK2/STAT3 signaling pathway,epithelial-mesenchymal transition(EMT),cell migration and cell proliferation.Besides,wound-healing and Transwell assays were carried out to investigate the cell migration and inva-sion.Colony formation and EdU assays were employed to investigate the cell proliferation,and flow cytometry analysis was performed to investigate the cell apoptosis.(3)The ADM mice were randomly divided into 2 groups:ADM group and AG490 group.The expression of IL-6/JAK2/STAT3 signaling pathway-related proteins in uterine tissues was detected by Western blot.Besides,Western blot and immunohistochemistry were employed to detect the expression of the proteins re-lated to cell EMT,migration and proliferation.Cell apoptosis in uterine tissues was detected by TUNEL assay.RE-SULTS:(1)The expression of IL-6/JAK2/STAT3 signaling pathway-related proteins exhibited an increasing trend in ADM mice(P<0.05).(2)Treatment with AG490 significantly suppressed the expression of IL-6/JAK2/STAT3 signaling pathway-related proteins in Ishikawa cells(P<0.05).The protein level of E-cadherin showed an increasing trend(P<0.01),while the expression levels of N-cadherin,vimentin and Slug showed a decreasing trend(P<0.05)in Ishikawa cells after AG490 treatment.Besides,the expression of MMP-2 and MMP-9 was down-regulated(P<0.05),and the capa-bilities of cell migration and invasion were suppressed in AG490-treated Ishikawa cells(P<0.05).The expression levels of Bcl-2 and cyclin D1 exhibited a decreasing trend(P<0.05),and the expression level of Bax increased(P<0.05)in Ishikawa cells after treatment with AG490.Additionally,AG490 inhibited Ishikawa cell proliferation,and enhanced the cell apoptosis(P<0.01).(3)The p-JAK2/JAK ratio and the IL-6 expression exhibited a decreasing trend in AG490 group(P<0.01).Moreover,the expression of E-cadherin was up-regulated(P<0.05),while the expression of N-cadherin,vi-mentin,Snail,Slug and Twist was down-regulated(P<0.05)in ADM mice after treatment with AG490.Compared with ADM group,the expression of MMP-2 and MMP-9 decreased in AG490 group(P<0.05),alongside the down-regulated Bcl-2/Bax ratio and PCNA expression(P<0.01).Besides,the cell apoptosis was enhanced by AG490.CONCLUSION:The IL-6/JAK2/STAT3 signaling pathway is aberrantly activated in ADM and facilitates endometrial cell EMT,prolifera-tion,invasion and migration.Additionally,AG490 inhibits the progression of ADM by blocking the IL-6/JAK2/STAT3 sig-naling pathway.

Abstract:
To establish a sleep deprivation model using zebrafish, and to provide more reliable practical modeling schemes for basic research on insomnia.
Methods:
A total of 160 male 4-month-old wild type AB zebrafish were randomly divided into control group(CK) and sleep deprivation group(SD1-SD7). The control group was placed in a normal 14 h/10 h alternating light/dark environment, and the sleep deprived group was subjected to different days of continuous light with simulated sunlight to achieve the effect of sleep deprivation. After modeling, the changes of movement form, learning and memory ability, biological clock gene expression and brain ultrastructure of zebrafish in each group were compared.
Results:
The results of movement form showed that compared with CK group, the resting time of zebrafish in SD1, SD2 and SD3 groups increased(P<0.05), and the movement time and movement count of zebrafish in SD3 group decreased(P<0.05). The results of learning and memory ability showed that zebrafish in CK group had better learning and memory ability than SD1, SD2 and SD3 groups(P<0.05,0.01), and zebrafish in SD1 group had better learning and memory ability than SD2 and SD3(allP<0.01), and zebrafish in SD2 group had better learning and memory ability than SD3(P<0.01). qRT-PCR results showed that compared with CK group, the mRNA expressions of Per1 a, Per2, Bmal1 and Cry1 b in the brain of zebrafish in SD3 group were significantly different(P<0.05). The results of electron microscopy showed that the neurons of zebrafish brain in SD2 and SD3 groups showed neuronal necrosis. Under the microscope, there were nuclear collapse, boundary cracking and even dissolution, chromatin shrinkage, mitochondrial swelling and even a large number of vacuoles.
Conclusion
Light exposure for 3 days can change the movement pattern of zebrafish, reduce its learning and memory ability, change the expression of clock genes related to sleep maintenance, and induce the apoptosis of brain neurons, which can be used to establish the model of zebrafish insomnia.
