The recovery from taxane mediated apoptosis in PC-3 castration-resistant metastatic prostate cancer cells.

Here, we revealed the reversibility of cabazitaxel (CBZ)-induced apoptosis in PC-3 castration resistant metastatic prostate cancer cells (mCRPC) through the hallmarks of apoptosis. The recovery of PC-3 cells from apoptosis upon removal of CBZ at different recovery periods was evaluated by Annexin V, DNA damage, oxidative damage, mitochondrial membrane depolarization, and caspase activation. Our results showed that the administration of CBZ caused apoptosis for 72 h in PC-3 cells.

Gamma-irradiated SARS-CoV-2 vaccine candidate, OZG-38.61.3, confers protection from SARS-CoV-2 challenge in human ACEII-transgenic mice.

The SARS-CoV-2 virus caused the most severe pandemic around the world, and vaccine development for urgent use became a crucial issue. Inactivated virus formulated vaccines such as Hepatitis A and smallpox proved to be reliable approaches for immunization for prolonged periods. In this study, a gamma-irradiated inactivated virus vaccine does not require an extra purification process, unlike the chemically inactivated vaccines.

Preclinical efficacy and safety analysis of gamma-irradiated inactivated SARS-CoV-2 vaccine candidates.

COVID-19 outbreak caused by SARS-CoV-2 created an unprecedented health crisis since there is no vaccine for this novel virus. Therefore, SARS-CoV-2 vaccines have become crucial for reducing morbidity and mortality. In this study, in vitro and in vivo safety and efficacy analyzes of lyophilized vaccine candidates inactivated by gamma-irradiation were performed.
