pinus massoniana/悪性腫瘍

The bark of Pinus massoniana is a traditional Chinese medicine for the treatment of various health disorders. Previous studies have demonstrated that P. massoniana bark extract (PMBE) may induce the apoptosis of hepatoma and cervical cancer cells. However, whether PMBE is able to inhibit the

Avian leukosis virus subgroup J (ALV-J) has resulted in considerable economic losses in the poultry industry. In recent years, fibrosarcoma induced by ALV-J, which contains the v-fps oncogene, has gained momentum, and this has brought about new challenges to the poultry industry. To study the

Pinus massoniana bark proanthocyanidins (PMBPs), an active component isolated from Pinus massoniana bark, has been reported to possess a wide range of biochemical properties. Here, we investigated the anti-tumor effect of PMBPs on ovarian cancer. The results indicated that PMBPs significantly

OBJECTIVE To explore the inhibitory effect of sulfated polysaccharide from Masson pine (Pinus massoniana) pollen (SPPM60) on G2/M phase of human liver cancer HepG2 cells and its mechanism. METHODS The proliferation rate of HepG2 cells was evaluated by methyl thiazolyl tetrazolium (MTT) colorimetric

Pinus massoniana bark extract (PMBE) contains a variety of flavonoids whose antioxidant properties have been confirmed in vitro. This study was undertaken to evaluate the cytotoxic effects and the mechanism of cell death on the PMBE-treated human cervical cancer cell line, HeLa. PMBE treatment led

Five diterpenoids and 14 known diterpenoids were isolated from the petroleum ether extract of Pinus massoniana resin. Their structures were elucidated by spectroscopic data interpretation. The cytotoxic activities of these compounds were evaluated using the MTT method. The results showed that three

Pinus massoniana Lamb is a Chinese red pine species used in traditional medicine for the treatment of a variety of human health disorders. Recent studies have shown that P. massoniana bark extract (PMBE) has an anti-proliferation effect on cancer cells. However, it is not clear if PMBE affects

A study was initiated with the objective of evaluating the effects of sonication treatment on important quality parameters of extract of Pinus massoniana pollen. Sonication of extract was done (frequency 20kHz and various amplitude levels) for 10, 30, 50min, respectively. As results, total

Pinus massoniana bark extract (PMBE) is a mixture of flavonoids, and showed a capability of inducing cell apoptosis; however, its properties have not yet been fully investigated. This paper evaluates the antitumor effects of PMBE in murine sarcoma S180 both in vitro and in vivo. In vitro, the growth

Pinus massoniana bark extract (PMBE) is a mixture of flavonoids, whose antioxidant and apoptosis-inducing properties have been confirmed in vitro. In this study, the apoptotic effect and mechanism of PMBE in HepG2 human hepatoma cells were evaluated. PMBE exerted dose- and time-dependent cell growth

Subgroup J avian leucosis virus (ALV-J) generally causes neoplastic diseases, immunosuppression and subsequently increases susceptibility to secondary infection in birds. The spread of ALV-J mainly depends on congenital infection and horizontal contact. Although ALV-J infection causes enormous

Proanthocyanidins (PAs) belong to the condensed tannin subfamily of natural flavonoids. Recent studies have shown that the main bioactive compounds of Pinus massoniana bark extract (PMBE) are PAs, especially the proanthocyanidins B series, which play important roles in cell cycle arrest, apoptosis

The inhibitory effects of procyanidine, one of the components from the bark of Pinus massoniana Lamb, on the P-glycoprotein (P-gp) function of the blood-brain barrier (BBB) were studied using in vitro rat brain microvessel endothelial cells (RBMECs) and nude mice transplanted with human cerebroma.
