cinnamaldehyde/hypoxia

Tumor hypoxia is positively correlated with tumor aggressiveness and hence is a negative prognostic factor in cancer. As normal cells usually do not experience such low oxygen levels, hypoxic cell signaling has attracted significant attention for the development of tumor-selective treatment

Melanoma is a highly malignant tumor originating from melanocytes. This disease is characterized by inconspicuous onset, high malignancy, and poor prognosis. The aim of this study is to explore the effect of cinnamaldehyde on melanoma tumorigenicity and its mechanism. Melanoma cells were

Our preliminary study shows that cinnamaldehyde (CA) could protect against intestinal ischemia/reperfusion (I/R) injuries, in which p53 and NF-κB p65 play a synergistic role. In this study, we conducted in vivo and in vitro experiments to verify this proposal. SD rats were pretreated with CA (10 or

One tough question induced by the hypoxia in cancer tissue is resistance to anticancer drugs basing on the reactive oxygen species (ROS) mechanism. Furthermore, the hypoxic regions locate in the center of tumor where tumor cells are easily residual and survival due to the poor drug-delivery

Apoptosis, overload Ca²⁺ entry and oxidative stress are induced in neurons by hypoxia. Drug-resistant cancer cells are killed by hypoxic conditions. α-Lipoic acid (ALA) has antioxidant and pro-oxidant functions. The TRPA1 channel is activated by oxidative stress and pro-oxidant ALA may

Oxaliplatin has been widely applied in clinical tumor chemotherapy, the treatment failure of which mainly blames on low susceptibility resulted from intrinsic or acquired drug resistance in tumor cells. Microenvironmental hypoxia is one of the important pathological features of solid tumors, which

Epithelioid cells in the chicken thoracic aorta are chemoreceptor cells that release 5-HT in response to hypoxia. It is likely that these cells play a role in chemoreception similar to that of glomus cells in the carotid bodies of mammals. Recently, H2S was reported to be a key mediator of carotid

Hypoxia and ischemia are linked to oxidative stress, which can activate the oxidant-sensitive transient receptor potential ankyrin 1 (TRPA1) channel in cerebral artery endothelial cells, leading to vasodilation. We hypothesized that TRPA1 channels in endothelial cells are activated by

Here, antitumor mechanism of cinnamaldehyde derivative CB-PIC was elucidated in human SW620 colon cancer cells. CB-PIC significantly exerted cytotoxicity, increased sub-G1 accumulation, and cleaved PARP with apoptotic features, while it enhanced the phosphorylation of AMPK alpha and ACC as well as
