Targeting AMPKa1 Gene in PC3 Cells by Triphenylmethanol Derivatives

引用

Natural Science 2024年第7期16卷 111-120页

作者： William Yaw Boadi Jamari Jemison Kennedy Welbert Sanaa Dudley Tayalla Hizer ryan Beni Departments of Chemistry and Biology Tennessee State University Nashville USA

Epidemiological studies indicate that treatment with metformin, an AMP-activated protein kinase (AMPK) activator, reduces the incidence of cancers. Activation of AMPK has also been reported to oppose tumor progression in diverse types of cancers and offers promising cancer therapy. Furthermore, AMPK is a primary regulator of energy metabolism and has also been implicated in cell cycle progression, angiogenesis, cell transformation, migration, and cancer. We have recently synthesized novel flavonoids, namely, triphenylmethanol derivatives (TPMs), but the effectiveness of the TPMs on the activity of AMPK remains unclear. We hypothesized that the novel TPMs would inhibit cancer cell proliferation through the activation of AMPK isoforms in cells. The effects of TPMs on prostate cells (PC-3) were investigated. Cells were exposed to TPMs for either 12 or 24 hr. at the respective doses of 0, 25, 50 100, and 200 µM based on the cell viability studies by the (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, a tetrazole) (MTT) assay. The results indicate that cells exposed to the respective doses of TPMs increased both phospho- and total-AMPKα1 in a dose- and time-dependent manner. The effects of the increases for the phospho- and total-AMPKα in cells were greater for the 24-hr than the 12-hr. incubation. Further studies are currently going on to elucidate the specificities of the said insults in increasing the phospho- and total-AMPKα activities and for the other respective isoforms.

本研究考察了COVID-19感知易感性、健康风险感知、风险规避与出游意愿之间的关系,并探讨了政府信任的调节作用。研究数据通过腾讯问卷(113)和实地调研(507)两种方法收集。研究发现:感知易感性显著影响健康风险感知和风险规避,这2个变量又显著影响游客的出游意愿。健康风险感知和风险规避分别在感知易感性影响出游意愿发挥部分中介作用,它们之间的链式中介关系也得到支持。政府信任在感知易感性影响健康风险感知,以及健康风险感知和出游意愿之间有显著的调节作用。本研究对全球公共卫生危机游客出游意愿的影响因素提供了新的见解,有助于后疫情时代旅游经济复苏和目的地的营销策略制定。
