DNA-protein cross-links (DPCs) are bulky, helix-distorting DNA lesions that form in the genome upon exposure to common antitumor drugs, environmental/occupational toxins, ionizing radiation, and endogenous free-radical-generating systems. As a result of their considerable size and their pronounced effects on DNA-protein interactions, DPCs can interfere with(More)
Ras family small GTPases localize at the plasma membrane, where they can activate oncogenic signaling pathways. Understanding the mechanisms that promote membrane localization of GTPases will aid development of new therapies to inhibit oncogenic signaling. We previously reported that SmgGDS splice variants promote prenylation and trafficking of GTPases(More)
Vaccination against the highly abused prescription opioid oxycodone has shown pre-clinical efficacy for blocking oxycodone effects. The current study further evaluated a candidate vaccine composed of oxycodone derivatized at the C6 position (6OXY) conjugated to the native keyhole limpet hemocyanin (nKLH) carrier protein. To provide an oxycodone vaccine(More)
Farnesyl diphosphate (FPP) is an important metabolic intermediate in the biosynthesis of a variety of molecules including sesquiterpenes and the side chains of a number of cofactors. FPP is also the source of isoprenoid side chains found attached to proteins. Enzymes that employ FPP as a substrate are of interest because they are involved in the(More)
Isoprenylcysteine carboxyl methyltransferases (Icmts) are a class of integral membrane protein methyltransferases localized to the endoplasmic reticulum (ER) membrane in eukaryotes. The Icmts from human (hIcmt) and Saccharomyces cerevisiae (Ste14p) catalyze the α-carboxyl methyl esterification step in the post-translational processing of CaaX proteins,(More)
Translation of therapeutic vaccines for addiction, cancer, or other chronic noncommunicable diseases has been slow because only a small subset of immunized subjects achieved effective Ab levels. We hypothesize that individual variability in the number of naive and early-activated hapten-specific B cells determines postvaccination serum Ab levels and vaccine(More)
