Pancreatic cancer has the worst prognosis of any major malignancy, with an annual death rate that approximates the annual incidence rate. Delayed diagnosis, relative chemotherapy and radiation resistance and an intrinsic biologic aggressiveness all contribute to the abysmal prognosis associated with pancreatic cancer. Answers to the frustrating effort to(More)
BACKGROUND Bmi1 is an integral component of the Polycomb Repressive Complex 1 (PRC1) and is involved in the pathogenesis of multiple cancers. It also plays a key role in the functioning of endogenous stem cells and cancer stem cells. Previous work implicated a role for cancer stem cells in the pathogenesis of pancreatic cancer. We hypothesized that Bmi1(More)
Toosendanin, a triterpenoid derivative isolated from Melia toosendan Sieb. et Zucc., possesses different pharmacological effects in humans and an important value in agriculture. As indicated by previous reports, the molecular mechanisms of toosendanin's anticancer effects remain poorly clarified. In this study we used both in vivo and in vitro models to(More)
Although metformin, a first-line drug for treating diabetes, may play an important role in inhibition of epithelial ovarian cancer cell growth and cancer stem cells (CSCs), metformin at low dose showed less effect on the proliferation of ovarian cancer cells. In this study, we evaluated the effect of metformin at low dose on ovarian CSCs in order to(More)
Fascin 1 (Fascin actin-bundling protein 1) is an actin-binding protein. Although several studies have reported the dysregulation of Fascin 1 in non-small cell lung cancer (NSCLC), its functions in the progression of NSCLC and the related molecular mechanism were not fully understood. In this study, the expression of Fascin 1 in NSCLC tissues was determined(More)
The relations among self-esteem, stress, and ingratiatory behaviors in the workplace were examined. Competing models for moderating and mediating effects of self-esteem on the relationship between stress and ingratiation were presented. Data from a sample of 136 employees at a state lottery organization were used to test the competing models. Support was(More)
