Transfected cells in the logarithmic growth phase were inoculated onto a 6-well plate and cultured for 1 day. Cells were xed in 70% ethanol for 24 h and treated with propidium iodide and RNase provided with the kit. The cell cycle distribution was detected by ow cytometry.
Dual Luciferase Reporter Assay HEK-293 cells were divided into the miR-30a-3p and pmirGLO empty vectors, miR-335-5p and pmirGLO-MAPK10-WT (GenePharma), miR-335-5p, and pmirGLO-MAPK10-MuT (GenePharma) co-transfection groups, respectively. Untreated cells were used as controls. Wild-type and mutant MAPK10 were synthesized by GeneChem (Shanghai, China) as follows: wild-type MAPK10, up 5 -cATTTAACTTCTAGTTGCTCTTGCc-3 and down 5 -tcgagGCAAGAGCAACTAGAAGTTAAATgagct-3 ; and mutant MAPK10, up 5 -cATTTAACTTCTAGTTGATATCGCc-3 and down 5 -tcgagGCGATATCAACTAGAAGTTAAATgagct-3 . Cells were inoculated onto 96-well plates and cultured for 24 h. Luciferase activity was detected using a microplate reader. Renilla luciferase was used as an internal reference.

MiR-mock, miR-410-3p, miR-410-5p, miR-590-5p, anti-miR-590-5p, anti-miR-410-5p, mmu-miR-1896-3p, and miR-335-5p were purchased from Gene Pharma (Suzhou, China). Sequence information for the miRNAs was obtained from the miRBase 19 (link)-23 (link)(http://microrna.sanger.ac.uk/sequences/). MiR-mock, miR-590-5p, and miR-410-5p were labeled with FAM at 5' end. mmu-miR-1896-3p, miR-335-5p, anti-miR-590-5p, anti-miR-410-5p, and miR-410-3p were labeled with Cy3 at 3' end. MiR-mockFAM + miR-410-3pCy3, miR-410-5pFAM + miR-410-3pCy3, and miR-410-5pFAM + mmu-miR-1896-3p, and miR-335-5pCy3 were co-transfected into RWPE-1 cells. miR-410-5pFAM + anti-miR-410-5pCy3, and miR-590-5pFAM + anti-miR-590-5pCy3 were co-transfected into RWPE-1 cells, as a positive control. The samples were analyzed at the indicated time points using the Amnis Image Stream mk II with the excitation wavelength set to 488 nm (FAM excitation) and emission set to 516 nm for FAM emission, and 568 nm for Cy3 emission. When the oligonucleotides bound to the complementary sequences in cells, a FRET signal was observed (downregulation of the FAM emission intensity and the detection of Cy3 fluorescence). All oligonucleotides are listed in Table S1.

MiR-mock, miR-410-3p, miR-410-5p, miR-590-5p, anti-miR-590-5p, anti-miR-410-5p, mmu-miR-1896-3p, and miR-335-5p were purchased from Gene Pharma (Suzhou, China). mmu-miR-1896-3p, miR-335-5p, miR-410-3p, miR-590-5p, and miR-410-5p were 5'-labeled with FAM and 3'-labeled with Cy3 (referred to as mmu-miR-1896-3p Fluor, miR-335-5pFluor, miR-410-3pFluor, miR-590-5pFlour, and miR-410-5pFlour respectively. MiR-mock + miR-410-3pFluor, miR-410-5p + miR-410-3pFluor, miR-410-5p + mmu-miR-1896-3p, and miR-410-5p + miR-335-5pFluor were co-transfected into RWPE-1 cells. miR-410-5p Fluor + anti-miR-410-5p, and miR-590-5p Fluor + anti-miR-590-5p were co-transfected into RWPE-1 cells as a positive control. The samples were also analyzed on the Amnis Image Stream mkII with the excitation wavelength set to 488 nm (FAM excitation) at the indicated time points; the emission wavelength was set to 516 nm (FAM emission) and 568 nm (Cy3 emission). When the labeled miRNA was degraded after binding to another oligonucleotide, Cy3 fluorescence was suppressed and the FRET signal vanished (downregulation of Cy3 emission intensity and upregulation of FAM fluorescence intensity). All oligonucleotides are listed in Table S1.

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.
