This observation was confirmed with an AlamarBlue cell viability assay by comparing RCK-8 and SUDHL-6 (Figure 1C), suggesting that low SAMHD1 expression is associated with DLBCL cell Veliparib greater sensitivity and consistent with a role for SAMHD1 in promoting HR. Here, SAMHD1 is linked to diffuse large B-cell lymphoma.
