IL1B and colorectal carcinoma: Our work treated CRC cells with Bupivacaine, detected cell vitality through MTT assay, apoptosis through flow cytometry, cell migration through wound healing assay, NF-κB activity through immunofluorescence, inflammatory factor level, including TNF-α, IL-1β as well as IL-6 through ESLIA, apoptosis factor mRNA expression, including Bcl-2, Bax and caspase-3q through qRT-PCR, and protein expression linking with NF-κB signaling pathway as well as autophagy-related proteins via western blot.
