Electronic address: firstname.lastname@example.org.AbstractHIV develops drug resistance at a high rate under drug selection pressure. Resistance tests are recommended to help physicians optimize antiretroviral drug therapies. For this purpose, genotypic and phenotypic tests have been developed. In order to propose a new phenotypic test that will be less laborious, expensive, and time consuming than the standard ones, a new procedure to measure HIV-1 protease susceptibility to protease inhibitor (PIs) in Saccharomyces cerevisiae yeast cells was developed. This procedure is based on HIV-1 protease expression in yeast. While the viral protein induces yeast cell death, its inhibition by PIs in the culture medium allows the cell to grow in a dose-dependent manner. In a comparative study of standard genotypic analysis vs. yeast cell-based phenotypic tests, performed on HIV-1 protease coding DNA in 17 different plasma samples from infected individuals, a clear match was found between the results obtained using the two technologies. This suggests that the yeast-based procedure is at least as accurate as standard genotypic test in defining susceptibility to protease inhibitors. This encouraging result should be the basis for large-scale validation of the new phenotypic resistance test.

- Comparative analysis of ER stress response into HIV protease inhibitors: Lopinavir but not darunavir induces potent ER stress response via ROS/JNK pathway.
- Taura M, Kariya R, Kudo E, Goto H, Iwawaki T, Amano M, Suico MA, Kai H, Mitsuya H, Okada S.Author information Division of Hematopoiesis, Center for AIDS Research, Kumamoto University, 2-2-1 Honjo, Kumamoto, 860-0811, Japan.AbstractHIV protease inhibitor (PI)-induced ER stress has been associated with adverse effects. Although it is a serious clinical problem for HIV/AIDS patients, comparative analyses of ER stress induction by clinically used PIs have rarely been done. Especially, there is no report on the differential ER stress response between lopinavir (LPV) and darunavir (DRV), although these PIs are the most clinically used PIs. We show here that LPV induces the most potent CHOP expression, ER stress marker, among the 9 Food and Drug Administration (FDA)-approved PIs in human peripheral blood mononuclear cells, several human epithelial cells, and mouse embryonic fibroblasts. LPV induced the most potent ROS production and JNK activation in 9 PIs. A comparison among the most clinically used PIs, ritonavir (RTV), LPV, and DRV, revealed that LPV potently and RTV moderately but not DRV induced ER stress via ROS-dependent JNK activation rather than proteasome inhibition. Finally, we analyzed ER stress induction in tissues of mice intraperitoneally injected with RTV, LPV, and DRV. RTV and LPV but not DRV showed ER stress induction in several mice tissues. In conclusion, we first identify LPV as the most potent ER stress inducing PI among 9 FDA-approved PIs in human cells, and although clinical verification is necessary, we show here that DRV has the advantage of less ROS and ER stress induction potential compared with LPV in vitro and in vivo.
