Ursolic acid, present in apples, rosemary, and other sources, is known to inhibit tumor formation and tumor cell viability in multiple systems, including skin. However, various cancers are resistant to ursolic acid treatment. Herein, skin carcinoma cells (Ca3/7) as compared with skin papilloma cells (MT1/2) displayed more resistance to ursolic acid-induced cytotoxicity. Interestingly, Ca3/7 cel...

The process of tumorigenesis requires cellular transformation, hyperproliferation, invasion, angiogenesis, and metastasis. Several genes that mediate these processes are regulated by the transcription factor nuclear factorB (NFB). The latter is activated by various carcinogens, inflammatory agents, and tumor promoters. Thus, agents that can suppress NFB activation have the potential to suppress...

PURPOSE Development of chemoresistance, poor prognosis, and metastasis often renders the current treatments for colorectal cancer (CRC) ineffective. Whether ursolic acid, a component of numerous medicinal plants, either alone or in combination with capecitabine, can inhibit the growth and metastasis of human CRC was investigated. EXPERIMENTAL DESIGN The effect of ursolic acid on proliferation...

In the present study, beneficial effect of leaves Ziziphus mauritiana on testosterone, estradiol, progesterone, LH hormones, blood glucose, and total cholesterol levels in experimentally induced polycystic ovaries female Sprague Dawley rats were evaluated. Letrozole was used to induce PCOS rats, clomiphene citrate as a standard control. This study carried out vivo 30 where group I received norm...

Background: Ursolic acid, a pentacyclic triterpenoid, is known to exert antitumor activity in breast, lung, liver and colon cancers. Nonetheless, the underlying mechanism of ursolic acid in prostate cancer cells still remains unclear. To investigate the antitumor mechanism, the apoptotic mechanism of ursolic acid via Wnt/b-catenin signaling was examined in PC-3 prostate cancer cells. Methods: C...

It has been reported that ursolic acid has anti-tumor activity and it enhances the therapeutic effect of oxaliplatin in colorectal cancer (CRC). However, the underlying mechanisms remain unknown. In the present study, the mechanisms of the enhancement of therapeutic effects through use of ursolic acid were investigated. We treated CRC cell lines HCT8 and SW480 with ursolic acid and oxaliplatin ...

Neutrophil activation is associated with the development of organ injury after trauma-hemorrhagic shock. In the present study, ursolic acid inhibited the superoxide anion generation and elastase release in human neutrophils. Administration of ursolic acid attenuated trauma-hemorrhagic shock-induced hepatic and lung injuries in rats. In addition, administration of ursolic acid attenuated the hep...

After 13,000 samples of compounds purified from plants were screened, a new biofilm inhibitor, ursolic acid, has been discovered and identified. Using both 96-well microtiter plates and a continuous flow chamber with COMSTAT analysis, 10 microg of ursolic acid/ml inhibited Escherichia coli biofilm formation 6- to 20-fold when added upon inoculation and when added to a 24-h biofilm; however, urs...
