Establishing Stable Gene Modulation in HCC Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The HCC cells including PLC/PRF/5, Huh7, HepG2, Hep3B, and MHCC-97L cells, as well as immortalized human hepatocytes (MIHA cells), were obtained from the Procell Life Science and Technology Company in China. Cells were seeded in culture plates with the RPMI 1640 medium (HyClone, USA) with 10% (v/v) fetal bovine serum (FBS) (Gibco, USA) at a humid incubator (37° C and 5% CO2). The cells were trypsinized by using 0.25% trypsin (Gibco, USA) and sub-cultured when cells reached 70-80% confluence. For the establishment of HCC cell lines with the stable knockdown/overexpression of corresponding genes, indicated constructs were induced into HCC cells through lentiviral infection. After that, cells were screened by adding 3 μg/ml puromycin or 5 μg/ml blasticidin.

Lentiviral Delivery of SGOL2 and MAD2 in HCC Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
The HCC cell lines SK-HEP-1 and HEP3B were purchased from Procell (Wuhan, China). All cells were cultured in DMEM (Gibco) supplemented with 10% fetal bovine serum (Gibco), 1% streptomycin, and penicillin. Cells were transfected with lentivirus or plasmid purchased from Shanghai Genomeditech (Shanghai, China) and verified by DNA sequencing. Lentiviruses containing shNC (negative control, NC) and shSGOL2 were constructed using the vector pGMLV-SC5. The shRNA sequence used to target SGOL2 was as follows: 5′-GGTCAGAATTCCCTAACTTGT-3′. The pGMLV-SGOL2 plasmid contained the SGOL2 coding sequence, and the pGMLV-MAD2 plasmid contained the MAD2 coding sequence. For plasmid transfection, SK-HEP-1 and HEP3B cells were seeded in 12-well plates and then transfected with plasmids (4 mg per well) using Lipofectamine 2000 Reagent (Invitrogen) according to the protocols. Cells were harvested for analysis after 48 h.

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.
