Abstract

Gastric cancer still presents a significant problem for public health worldwide. Troxerutin (TXN), a flavonoid present in tea, coffee, cereal grains, and a variety of fruits and vegetables, exhibits various pharmacological and biological activities in vitro and in vivo. We investigated the ability of TXN to reverse the in vitro and in vivo drug resistance of human gastric cancer cells, which were resistant to treatment of 5-Fluorouracil (5-FU). 5-Fu is a pyrimidine analog, which is widely used in the treatment of cancers. Here, we found the growth inhibitory effects of TXN on human gastric cancer cell, resistant to 5-FU. TXN and 5-FU co-treatment resulted in a dose-dependent suppression of the cell proliferation. Decreasing of phosphorylated signal transducers and activation of transcription 3 (STAT3) was included in suppression of p65 by TXN with 5-FU in combination. Additionally, the presence of TXN sensitized gastric cancer cells resistant to 5-FU to 5-FU-induced apoptosis by suppressing Bcl-2. The pro-apoptotic proteins of Bax and Bid were up-regulated, accompanied with Caspase cleavage, leading to apoptosis. Moreover, in mice xenograft models, the combined therapy inhibited tumor growth compared to the TXN or 5-FU treatmen...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

BCL-2 Family Proteins

BLC-2 family proteins are a group that share the same homologous BH domain. They play many different roles including pro-survival signals, mitochondria-mediated apoptosis and removal or damaged cells. They are often regulated by phosphorylation, affecting their catalytic activity. Here is the latest research on BCL-2 family proteins.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.
