Ticular tissue fixative (Servicebio, Wuhan, China) for 24 h and then transferred
Ticular tissue fixative (Servicebio, Wuhan, China) for 24 h and then transferred to 70 ethanol for storage. Soon after embedding of tissues in paraffin, 5-m thick sections have been obtained. Tissue morphology was observed using hematoxylin and eosin (HE) staining in line with the manufacturer’s guidelines (Solarbio, Beijing, China).TUNEL assayParaffin-embedded testicular tissue sections had been used for the TUNEL assay to decide apoptotic cells in tissues. TUNEL-positive cells have been detected making use of a DNA Fragmentation Detection Kit (Merck Millipore, Billerica, MA, USA), in line with the advised protocol.Cell culture, transfection, and reagentsR2C cells bought in the China Infrastructure of Cell Line Sources (Beijing, China) had been transfected with miRNA mimics for gain-of-function experiments, and miRNA inhibitors (GenePharma, Shanghai, China) for loss-of-function experiments. Cell transfection was performed applying Lipofectamine 3000 (Invitrogen, Carlsbad, CA, USA) following the manufacturer’s guidelines. miR504 mimic (sense:5-AGACCCUGGUCUGCA CUCUGUC-3, antisense: 5-CAGAGUGCAGACCAG GGUCUUU-3), mi504 inhibitor (5-GACAGAGUG CAGACCAGGGUCU-3), miR935 mimic (sense:5-CCA GUUACCGCUUCCGCUACCGC-3, antisense: 5-GGU AGCGGAAGCGGUAACUGGUU-3), mi935 inhibitor (5-GCGGUAGCGGAAGCGGUAACUGG-3), mimicNC (sense:5-UUCUCCGAACGUGUCACGUTT-3, antisense: 5-ACGUGACACGUUCGGAGAATT-3) and inhibitor NC(5-CAGUACUUUUGUGUAGUACAA-3) have been transfected at a final concentration of 50 nM for 24 h. Cell culture was maintained in DMEM (GIBCO, Grand Island, NY, USA) supplemented with 10 FBS (GIBCO,) inside a humidified air incubator with five CO2 at 37 . Leydig cells have been exposed to standard (5 mM) or moderately higher (15 mM) or high (30 mM) glucose concentrations for 48 h according to the previous study (Karpova et al. 2020).Realtime quantitative PCR (RTqPCR)extracted from blood employing a QIAamp RNA Blood Mini Kit (QIAGEN, Duesseldorf, Germany). Total RNA from tissues and cells was extracted working with a TaKaRa MiniBEST Universal RNA Extraction Kit (TaKaRa, Tokyo, Japan) following the manufacturer’s instructions. For the quantification of miRNA by qPCR, reverse transcription and RT-qPCR were performed using the Mir-X miRNA RT-qPCR TB GreenKit (TaKaRa) and Mite Inhibitor supplier normalized to U6. The complete sequence of mature miRNA was utilised as miRNA distinct, five primer (miR-504, 5-AGACCCUGG UCUGCACUCUGUC-3′ miR-935, 5-CCAGUUACC GCUUCCGCUACCGC-3; miR-484, 5-UCAGGCUCA GUCCCCUCCCGAU-3; miR-301a-5p, 5-GCUCUG ACUUUAUUGCACUAC-3; U6, 5-CGTTCACGAATT TGCGTGTCAT-3). The three primer employed within the qPCR was the mRQ three primer supplied together with the kit. Reverse transcription of mRNA was performed employing the PrimeScriptTM RT Master Mix (TaKaRa), although RT-qPCR was performed working with the A single Step TB GreenPrimeScriptTM RT-qPCR Kit II (TaKaRa) and normalized to -actin. The primers applied had been as follows: MEK5 forward primer 5-TCGTGCCATGGAGAACCA-3, reverse primer 5-CGCGCCACTATTTGGAATCT-3; MEF2C forward primer 5-ACCACCACCCCATCGAGATA-3, reverse primer 5-GGAGTGGAATTCGTTCCGGT-3; -actin forward primer 5-ATGGATGACGATATCGCTGC-3, reverse primer 5-CTTCTGACCCATACCCACCA-3. The 2Cq process was employed to evaluate the relative levels of mTOR Modulator custom synthesis expression of miRNA and mRNA (Livak and Schmittgen 2001).Western blot analysisBlood samples were obtained from patients with diabetes and healthful donors at Shenzhen University Common Hospital. This project was authorized by the ethics committee with the Shenzhen University. Total RNA wasWestern blot evaluation was performed accordin.
