soyasaponin/neoplasms

Afromosin [1] and soyasaponin I [2] isolated from Wistaria brachybotrys exhibited remarkable inhibitory effects on mouse skin tumor promotion, and afromosin also exhibited a significant inhibitory effect on pulmonary tumor promotion. The combined effects of these compounds on the two-stage skin

Triterpenoid B-group soyasaponins have been found to induce macroautophagy in human colon cancer cells at concentrations obtainable through consumption of legume foodstuffs. In the present studies the mechanism(s) for this autophagy-inducing action of soyasaponins was evaluated by measuring changes

Soyasaponins are bioactive compounds found in many legumes. Although crude soyasaponins have been shown to have anti-colon carcinogenic activity, there have been no structure-activity studies. In this study, therefore, purified soyasaponins and soyasapogenins were tested for their ability to

The protective effects of soyasaponins-rich extract (SRE) from soybean against acute alcohol-induced hepatotoxicity were first investigated in the Institute of Cancer Research mice. Administration of SRE prior to alcohol significantly prevented the increases in serum aspartate transaminase, alanine

Soybeans (Glycine max L. Merill) and soy-based food products are major dietary sources of saponins. An oleanane triterpenoid saponin, soyasaponin Bh (1) containing a unique five-membered ring with a hemiacetal functionality together with seven known saponins were isolated from soybeans. Their

It appears to be more practical and effective to prevent carcinogenesis by targeting the tumor promotion stage. Gap junctional intercellular communication (GJIC) is strongly involved in carcinogenesis, especially the tumor promotion stage. Considerable interest has been focused on the

This study demonstrates the effect of soybean components on the tumor necrosis factor-alpha (TNF-alpha)-induced production of interleukin-8 (IL-8), one of the major inflammatory chemokines, in intestinal epithelial-like Caco-2 cells. Among the soybean components, an isoflavone fraction (IFF)

Background: Previous studies indicate that soyasaponins may reduce inflammation via modulating toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88) signaling. However, its underlying mechanisms are still not fully

Soy (Glycine Max Merr, family Leguminosae) has been reported to possess anti-cancer, anti-lipidemic, estrogen-like, and memory-enhancing effects. We investigated the memory-enhancing effects and the underlying mechanisms of soyasaponin I (soya-I), a major constituent of soy. Impaired learning and

Ethnopharmacological relevance: The beneficial effect of bee pollen in inflammatory conditions of prostate gland is known for a long time. Clinicians confirm that, in nonbacterial prostate inflammations, bee pollen improves the condition

The impact of triterpenoid saponins isolated from soybeans on suppression of colon cancer cell proliferation was evaluated. Experiments were conducted to determine the effects of a purified soybean B-group saponin extract on cell proliferation, cell-cycle distribution and programmed cell death in

Epithelial ovarian cancer (EOC) has the highest mortality rate among gynecologic cancers due to advanced stage presentation, peritoneal dissemination, and refractory ascites at diagnosis. We investigated the role of α2,3-sialyltransferase type I (ST3GalI) by analyzing human ovarian cancer datasets

The transfer of sialic acids to the non-reducing terminal positions on sugar chains of glycoconjugates is catalyzed by sialyltransferases (STs). Increased sialylation is correlated with oncogenic transformation and metastatic potential. ST inhibitors may be potentially valuable as anti-cancer and

The anti-inflammatory properties of soyasaponins (especially soyasaponins with different chemical structures) have scarcely been investigated. We investigated the inhibitory effects of five structural types of soyasaponins (soyasaponin A(1), A(2), I and soyasapogenol A, B) on the induction of nitric

Many clinical studies have shown that daily intake of soybean [ Glycine max (L.) Merr., Fabacease] or its foods may reduce the risk of osteoporosis, heart attack, hyperlipidemia, coronary heart disease, cardiovascular and chronic renal diseases, and cancers, including prostate, colon, and breast
