The epithelial-mesenchymal transition (EMT) serves vital roles in the angiogenesis, cell invasion and metastasis of various malignant tumors, including bladder cancer. Traditional Chinese medicinal herbs have been demonstrated to exhibit anticancer properties. The present study aimed to screen the sensitivity of bladder cancer to natural compounds by using six classic anti-inflammatory and detoxifying herbs, including the ethanol extract of Paris polyphylla (PPE), Scutellaria barbata, Pulsatillae decoction, Dahuang Huanglian Xiexin decoction, Bazhengsan and Hedyotis diffusa combined with S. barbata, were used to treat bladder cancer cells in vitro. Bladder cancer was more sensitive to PPE compared with the other tested herbs, and PPE significantly suppressed bladder cancer cell migration and invasion. Thus, the present study focused on PPE. Bladder cancer cells were treated with monomer components of PPE, including polyphyllin (PP) I, PPII, PPVI and PPVII. The results demonstrated that PPII treatment significantly inhibited cancer cell migration and invasion, increased the expression level of E-cadherin and decreased the levels of N-cadherin, snail family transcriptional repressor 2, twist family bHLH transcription factor 1, matrix metallopeptidase (MMP) 2 and MMP9 compared with those in the control group (untreated cells). These results suggested that PPII treatment may suppress bladder cancer cell migration and invasion by regulating the expression of EMT-associated genes and MMPs. Therefore, PPE and PPII may have antimetastatic effects and PPII may serve as a potential therapeutic option for inhibiting bladder cancer metastasis.
Bladder cancer is among the top ten most common cancer types in the world, with approximately 550,000 new cases annually. The highest burden of bladder cancer is currently falling on most developed communities across the globe. But with an anticipated shift in world demographics with growing and aging populations mainly on the African continent, and important shifts in exposure to different risk factors across the world, this is likely to change over the next decades. In this review, we provide ...

: Rhizoma Paridis, a traditional Chinese medicine, has shown promise in cancer prevention and therapy. Polyphyllin II is one of the most significant saponins in Rhizoma Paridis and it has toxic effects on kinds of cancer cells. However, our results in this study proved that the polyphyllin II has hepatotoxicity in vitro through caspases activation and cell-cycle arrest. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide results indicated polyphyllin II inhibited proliferation, induced...

Vasculogenic mimicry (VM) is a functional microcirculation pattern formed by aggressive tumor cells and is related to the metastasis and poor prognosis of many cancer types, including hepatocellular carcinoma (HCC). Thus far, no effective drugs have been developed to target VM. In this study, patients with liver cancer exhibited reduced VM in tumor tissues after treatment with Rhizoma Paridis. Polyphyllin I (PPI), which is the main component of Rhizoma Paridis, inhibited VM formation in HCC line...

Abstract The aberrant expression of cancerous inhibitor of protein phosphatase 2A (CIP2A) indicates poor prognosis and promotes EMT and metastasis. EMT, a crucial cellular process that occurs during cancer progression and metastasis, has been reported to promote drug resistance in several previous studies. Consequently, ongoing research has been focused on exploring therapeutic options for preventing EMT to delay or reverse drug resistance. Polyphyllin I (PPI) is a natural component extracted fr...

PURPOSE OF REVIEW: We review the influence of nutrition and lifestyle on bladder cancer incidence and recurrence and summarize food items, diets and lifestyle practices that physicians may wish to prioritize for discussion with their patients. RECENT FINDINGS: Recent study results suggest an association between bladder cancer incidence and several food items including meat, fruit, vegetables, milk products and oil. Micronutrient deficiency is associated with bladder cancer risk; however, it rema...

In traditional Chinese medicine (TCM) theory, pathogenic heat and toxins, which are akin to the inflammatory factors, are the causes of cancer and could promote its virulent development. Therefore, heat-clearing and detoxicating (HCD) herbs are essential components of TCM formulas for cancer treatment. An increasing interest has been focused on the study of HCD herbs and accumulated evidences have shown that HCD herbs or HCD herbs-based formulas exhibited remarkable anticancer effects when used ...
Acquired resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) is the most important limiting factor for treatment efficiency in EGFR-mutant non-small cell lung cancer (NSCLC). Much work has linked the epithelial-mesenchymal transition (EMT) to the emergence of drug resistance, consequently, ongoing research has been focused on exploring the therapeutic options to reverse EMT for delaying or preventing drug resistance. Polyphyllin I (PPI) is a natural compound iso...

Paris polyphylla, a traditional antipyretic-detoxicate chinese medicinal herb, has been applied extensively in cancer treatments for nearly 2000 years. The purpose of the present study is to evaluate the potential anti-osteosarcoma effects of Paris polyphylla ethanol extract (PPEE) and to investigate its underlying mechanisms. The antiproliferation activity of PPEE was tested on 143B, MG-63, U-2 OS and hFOB1.19 cells using MTT assay. The pro-apoptotic and cell cycle arrest effects of PPEE were c...

Abstract Context Bladder cancer has become a common cancer globally, with an estimated 430 000 new cases diagnosed in 2012. Objective We examine the most recent global bladder cancer incidence and mortality patterns and trends, the current understanding of the aetiology of the disease, and specific issues that may influence the registration and reporting of bladder cancer. Evidence acquisition Global bladder cancer incidence and mortality statistics are based on data from the International Agenc...
