The main tackle of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistance after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Natural compounds deriving from traditional Chinese medicine are known to have low toxicity and genuine promising effects in reversing multidrug resistance, either induced by orthodox chemotherapeutic or targeted therapy drugs...

Liver cancer is one of the major diseases affecting human health. Modified drug delivery systems through the asialoglycoprotein receptor, which is highly expressed on the surface of hepatocytes, have become a research focus for the treatment of liver cancer. Resibufogenin (RBG) is a popular traditional Chinese medicine and natural anti-cancer drug that was isolated from Chansu, but its cardiotoxicity and hydrophobicity have limited its clinical applications. Galactosyl-succinyl-poloxamer 188 and galactosyl-succinyl-poloxamer 188-polylactide-co-glycolide (Gal-SP188-PLGA) were synthesized using galactose, P188, and PLGA to achieve active liver-targeting properties...

Arenobufagin, an active component isolated from the traditional Chinese medicine Chan Su, exhibits anticancer influences in several human malignancies. However, the effects and action mechanisms of arenobufagin on non-small-cell lung cancer (NSCLC) are still unknown. In this study, we reported that arenobufagin acted through activation of Noxa-related pathways and promoted apoptotic cell death in human NSCLC cells. Our results revealed that arenobufagin-induced apoptosis was caspase-dependent, as evidenced by the fact that caspase-9, caspase-3 and poly (ADP-ribose) polymerase (PARP) were cleaved, and pretreatment with a pan-caspase inhibitor Z-VAD-FMK inhibited the pro-apoptosis effect of arenobufagin...

Disablement affects over 40% of patients with advanced stage cancer, devastates their quality of life (QoL), and increases their healthcare costs. Proactively treating the causes of disablement; physical impairments, pain, and immobility, can prolong functional independence, improve QoL and, potentially, reduce utilization. However rehabilitation service delivery models are reactive in nature and focus on catastrophic rather than incipient disability. A validated collaborative approach, the Three Component Model (TCM), optimizes important clinical outcomes and may provide an ideal framework to overcome barriers to proactively integrating rehabilitation into cancer care...

Arsenic sulfide (As4S4) is the main component of Realgar which is widely used in traditional Chinese medicine. Previously we showed that As4S4 inhibited the proliferation of colon cancer cells through regulating nuclear factor of activated T cells (NFAT) pathway. Here we explore the role of NFAT in gastric cancer. We showed that As4S4 inhibited the expression of NFATc1, NFATc3, and NFATc4, and modulated the expression of NFATc2 accompanying with p53. The baseline expression of NFATc3 varied distinctly in gastric cancer cell lines (AGS, MGC803, MKN28, MKN45, and SGC7901) and the sensitivity of these cells to As4S4 was dissimilar, with AGS and MGC803 cells showing higher sensitivity while the SGC7901 cells relatively resistant...

The pancreatic cancer is among the most aggressive malignancies with strong proclivity to metastasis. The malignancy during pancreatic cancer progression is largely ascribed to epithelial-mesenchymal transition (EMT). Here we showed that toosendanin (TSN), which is an active component in traditional Chinese medicine, can strongly attenuate pancreatic cancer progression. TSN suppressed the viability and grow of pancreatic cancer cells in a dose-dependent manner. The migration and invasion of pancreatic cancer cells were also consistently inhibited dose-dependently...
