Deficiency or mutation in the p53 tumor suppressor gene commonly occurs in human cancer and can contribute to disease progression and chemotherapy resistance. Currently, although the pro-survival or pro-death effect of autophagy remains a controversial issue, increasing data seem to support the idea that autophagy facilitates cancer cell resistance to(More)
Colorectal cancer (CRC) is still the third most common cancer and the second most common causes of cancer-related death around the world. Metformin, a biguanide, which is widely used for treating diabetes mellitus, has recently been shown to have a suppressive effect on CRC risk and mortality, but not all laboratory studies suggest that metformin has(More)
Autophagy is a lysosomal degradation process which is key for the regulation of the turnover of long-lived or damaged proteins and organelles and which promotes cell survival during nutrient deprivation or other microenviron-mental stresses. Current evidence supports the hypothesis that autophagy suppresses tumorigenesis, particularly during the early(More)
Autophagy is an evolutionarily conserved catabolic process by which cellular components are sequestered into a double-membrane vesicle and delivered to the lysosome for terminal degradation and recycling. Accumulating evidence suggests that autophagy plays a critical role in cell survival, senescence and homeostasis, and its dysregulation is associated with(More)
In this study, the potential helper genes were identified through the data analysis of transcriptomic and proteomic profiling in recombinant Pichia pastoris cultured under simulated microgravity (SMG). Co-expressing of four genes PRX1, YAP1, AHA1, and YPT6, involved in the oxidative stress response and protein folding, exhibited promising helper factor(More)
p53 mutation is known to contribute to cancer progression. Fascin is an actin-bundling protein and has been recently identified to promote cancer cell migration and invasion through its role in formation of cellular protrusions such as filopodia and invadopodia. However, the relationship between p53 and Fascin is not understood. Here, we have found a new(More)
Angiogenesis has been an attractive target for drug therapy. Aloin (AL), an natural compound derived from Aloe barbadensis Miller leaves, has been shown to possess anti-cancer potential activities. However, its roles in tumor angiogenesis and the involved molecular mechanism are unknown. To evaluate the antiangiogenic and anticancer activities of AL,(More)
