Abstract
Salidroside is a phenolic secondary metabolite present in plants of the genus Rhodiola, and studies investigating its extensive pharmacological activities and mechanisms have recently attracted increasing attention. This review summarizes the progress of recent research on the antiproliferative activities of salidroside and its effects on breast, ovarian, cervical, colorectal, lung, liver, gastric, bladder, renal, and skin cancer as well as gliomas and fibrosarcomas. Thus, it provides a reference for the further development and utilization of salidroside.

Abstract
Evidence has suggested that salidroside inhibits the proliferation and invasion of renal clear cell, lung, breast, and colon cancer. However, effect of salidroside on colorectal cancer (CRC) cells against oxaliplatin (L-OHP) resistance remains unclear. In the present study, the CRC HT-29 cell line and L-OHP resistance HT-29/L-OHP cell line were used to evaluate the effect, and mechanism of salidroside on L-OHP resistance. The results demonstrated that the activity of HT-29 cells was lower compared with that of HT-29/L-OHP cells following L-OHP intervention, and was accompanied with varied expression levels of drug resistant proteins. The combination of salidroside and L-OHP weakened cell activity significantly compared single utilization. Compared with the control group, salidroside intervention resulted in a higher percentage of HT-29/L-OHP cells in the G0/G1 stage, and reduced percentage in the G2/M stage, but no significant variation in the S stage. The HT-29/L-OHP cells exhibited increased apoptosis rates and caspase-3 activity, but decreased metastatic, and invasive abilities following salidroside intervention. Quantitative polymerase chain reaction and western blot analysis detected variations in the expression levels of associated genes in HT-29/L-OHP cells following salidroside intervention. In all, the results of the present study revealed that salidroside is able to decrease the activity and invasive capacity of HT-29/L-OHP cells, and treatment with salidroside is associated with increased apoptosis of cancer cells through the regulation of certain genes.

J Cancer 2017; 8:2636-2642. [PMID: 28900501 PMCID: PMC5595093 DOI: 10.7150/jca.19873] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Accepted: 06/30/2017] [Indexed: 12/25/2022] Open
Abstract
Vincristine is extensively used chemotherapeutic medicine to treat leukemia. However, it remains a critical clinical problem with regard to its toxicity and drug-resistance. AMP-activated protein kinase (AMPK) is an energy sensor that is pivotal in maintaining cell metabolic homeostasis. It is reported that AMPK is involved in vincristine-induced apoptosis. However, whether AMPK is involved in chemotherapy-resistance is largely unclear. It is well-documented that metformin, a widely used medicine to treat type II diabetes, possesses anti-cancer activities, yet whether metformin affects leukemia cell viability via vincristine is unknown. In this study, we showed that both AMPKα1 mRNA and phosphorylated AMPK protein levels were significantly decreased in clinical leukemia samples. We further demonstrated that metformin sensitized leukemia cells to vincristine-induced apoptosis in an AMPK-dependent manner. In addition, knockdown of AMPKα1 significantly reduced the effects of metformin on vincristine-induced apoptosis. Taken together, these results indicate that AMPK activation is critical in metformin effects on vincristine-induced apoptosis and suggest a putative strategy of a combination therapy using metformin and vincristine in treatment of leukemia.
