For quantitative real-time PCR (RT-PCR) analysis, total RNA from cells was isolated using RNA simple Total RNA Kit (Tiangen Biotech), and miRNAs were performed using the miRcute miRNA isolation kit (Tiangen Biotech) according to the manufacturer’s instructions. RT-PCR was performed using Hairpin-it™ miRNAs RT-PCR Quantitation Kit (GenePharma, China) and samples were amplified for 40 cycles as follows: 95°C for 12 s, 62°C for 40 s, and 72°C for 30 s. The miR-106a expression was calculated relative to U6 snRNA. For Western blotting, proteins were loaded onto 12 or 15% SDS-PAGE gels and transferred to a polyvinylidene difluoride membrane (PVDF). Membranes were blocked in 5% non-fat milk in PBST for 1 h, and incubated with anti-ULK1(Abcam, ab167139), anti-ATG16L1 (Abcam, ab188642), anti-ATG7 (Abcam, ab52472), anti-LC3 (Abcam, ab51520), and anti-GAPDH (Abcam, ab245355). Immunoreactive band was performed using ECL reagent (Amersham Pharmacia) and quantified by using Image J software (NIH).

The total proteins in the testis tissues were separated using a Total Protein Extraction Kit (BC3711, Solarbio). The protein concentration was measured using a Protein Assay kit (Beyotime). Next, the protein samples were separated by 10% SDS-PAGE and electrically transferred to PVDF membranes (Millipore, MA, USA). After sealing with 3% bovine serum albumin at room temperature for 1 h, the membranes were hatched with the primary antibodies (rabbit anti-prohibitin (PHB), ab28172, 1:1000; rabbit anti-Beclin-1, ab62557, 1:2000; rabbit anti-LC3II/I, ab128025, 1:1,000; rabbit anti-p62, ab56416, 1:1,000; rabbit anti-SCF, ab64677, 1:1000; rabbit anti-Parkin, ab15494, 1:1,000; rabbit anti-LKB1, ab199970, 1:1,000; rabbit anti-AMPKα, ab131512, 1:500; rabbit anti-phosphorylated AMPKα (p-AMPKα), ab133448, 1:10000; rabbit anti-ULK1, ab167139, 1:1000; rabbit anti-p-ULK1, ab203207, 1:1000; rabbit anti-β-actin, ab8227, 1:5000; Abcam, Cambridge, UK) overnight at 4 °C. The membranes were incubated with goat-anti-rabbit IgG (H + L)-HRP (1:10000, ab6721, Abcam) for 1 h at room temperature and then rinsed thrice with TBST thrice. Protein bands were visualized using an Electrochemilluminescence (ECL) chemiluminescence kit (WBULS0500; EMD Millipore), and band intensity was analyzed with Image-Pro Plus 6.0.

Total protein was isolated from the cells using RIPA buffer (Beyotime Institute of Biotechnology, Inc.). The proteins were quantified using a NanoDrop 2000c spectrophotometer (Thermo Fisher Scientific, Inc.). A total of 20 µg proteins were separated by 10% sodium dodecyl sulfonate-polyacrylamide gel (SDS-PAGE; Beijing Solarbio Science & Technology Co., Ltd.) and then transferred onto polyvinylidene difluoride membranes (PVDF; Pall Corporation). The membranes were blocked in skim milk for 1 h at room temperature and incubated with primary antibodies against microtubule-associated protein light chain 3-I/II (LC3-I/II; ab192890; 1:2,000; Abcam), p62 (ab56416; 1:2,000; Abcam), ULK1 (ab167139; 1:1,000; Abcam) or GAPDH (ab9485; 1:2,500; Abcam) overnight at 4°C followed by incubation with corresponding secondary antibody (ab150117; 1:2,000; Abcam) for 2 h at room temperature. The protein levels were analyzed using an enhanced chemiluminescence kit (Vazyme Biotech Co., Ltd.). The results were analyzed using software ImageJ v1.8.0 (National Institutes of Health).

Cells were lysed in RIPA buffer with protease inhibitors and phosphate inhibitors. Protein was loaded onto an SDS-PAGE mini-gel and transferred onto a PVDF membrane. The blots were probed with the following primary antibodies: anti-LC3 (ab48394, Abcam, Cambridge, MA, USA), anti-Beclin 1 (ab207612, Abcam), anti-p62 (ab56416, Abcam), anti-ULK1 (ab167139, Abcam), anti-ATG5 (ab108327, Abcam), anti-ATG4A (ab108322, Abcam) Next, the blots were probed with the HRP-conjugated secondary antibody. Signals were visualized using ECL Substrates (Millipore, USA). GAPDH served as the loading control.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human gastric adenocarcinoma cell lines MGC80-3 and HGC-27 were provided by Dr. Yunshan Wang (Jinan Central Hospital Affiliated to Shandong University, Jinan, China). They were tested and authenticated by short tandem repeat profiling (Jinan Dean Forensic Identification Institute, Jinan, China) in September 26, 2019. Esophageal adenocarcinoma cell line OE33 was purchased from JENNIO Bio-Technology Company (Guangzhou, China), and authenticated using short tandem repeat analysis by JENNIO Biotech on May 8, 2018. Human MGC80-3, HGC-27 and OE33 cells were cultured at 37 °C with 5% CO2 using DMEM or RPMI-1640 media with 10% fetal bovine serum (Hyclone). Genotypes of MGC80-3, HGC-27 and OE33 cells were identified by Sanger sequencing. Mimics and inhibitors of miR-1262, siRNAs of ULK1 or the negative control RNA duplex (NC) which was nonhomologous to any human genome sequence were synthesized by Genepharma (Shanghai, China). Small RNAs were transfected into MGC80-3, HGC-27 and OE33 cells with INTERFERin® (Polyplus). Antibodies against ULK1 (abcam, ab167139) and β-Actin (abcam, ab8226) were used.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
