The SJSA-1 7.2 subline, established from a SJSA-1 tumor treated daily for two weeks with 100 mg/kg of SAR405838, contains a single heterozygous C176F mutation of its p53 but is only moderately less sensitive to SAR405838 than the parental SJSA-1 cell line in several assays. Here, TP53 is linked to neoplasm.
