  • WB analysis of HeLa using 85256-4-RR (same clone as 85256-4-PBS)

    WB analysis of HeLa using 85256-4-RR (same clone as 85256-4-PBS)

    HeLa cells were subjected to SDS PAGE followed by western blot with 85256-4-RR (COL4A1 antibody) at dilution of 1:2000 incubated at room temperature for 1.5 hours. This data was developed using the same antibody clone with 85256-4-PBS in a different storage buffer formulation.

  • IHC staining of human colon using 85256-4-RR (same clone as 85256-4-PBS)

背景介绍

COL4A1 (Collagen Type IV Alpha 1 Chain) encodes a major component of type IV collagen, which is an essential structural element of basement membranes in various tissues. COL4A1 forms heterotrimers with other collagen type IV chains (e.g., COL4A2) and interacts with extracellular matrix components such as laminins, proteoglycans, and perlecans. Proteolytic cleavage of the non-collagenous domain of COL4A1 produces a fragment called arresten, which has anti-angiogenic and tumor suppressor properties. Elevated expression of COL4A1 has been observed in various cancers, including hepatocellular carcinoma (HCC), where it promotes tumor growth and metastasis through the FAK-Src signaling pathway. COL4A1 is highly expressed in various tissues, including the placenta, fat, and other organs. The expression of COL4A1 can be regulated by transcription factors such as RUNX1, which has been shown to upregulate COL4A1 in hepatocellular carcinoma.
