The present study was undertaken to investigate antioxidant, antigenotoxic, and antiproliferative activity of butanol fraction (Bmbu) from bark of medicinal plant Butea monosperma. Antioxidant potency of Bmbu was examined by various in vitro assays. It was also investigated for antigenotoxic
Active immunotherapy with materials extracted from a murine methylcholanthrene-induced sarcoma using single phase solutions of 2.5% 1-butanol evoked host resistance against supralethal burdens of neoplastic cells deposited subcutaneously or delivered hematogenously. After curative resection of
Simian virus 40 (SV40)-induced sarcomas and adenovirus 7-induced sarcomas (Adv-7) exhibit both specific tumor-specific transplantation antigens (TSTA) and cross-protective embryonic antigens at the cell surface in the LAK:LVG(SYR) strain of Syrian golden hamsters. Specific SV40 TSTA could be
4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone is a potent and abundant procarcinogen found in tobacco smoke, and glucuronidation of its major metabolite, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), by UDP-glucuronosyltransferases (UGT) including UGT2B17 is an important mechanism for
The herb Butea monosperma constitutes several human health beneficial components, which are mostly studied for their anticancer effects. In this study, the activity of n-butanol fractions of B. monosperma floral extract was examined on inhibiting aberrant crypt foci (ACF) formation in azoxymethane
Pterocephalus hookeri is a widely applied Tibetan medicinal prescription for treatment of diseases such as flu, rheumatoid arthritis, and enteritis in China. It has been reported that Pterocephalus hookeri has anti-inflammatory and analgesic actions. However, the antitumor activity of Pterocephalus
Generation of cytotoxic T lymphocytes (CTL) in vitro and tumor-rejection responses by sensitization of semi-syngeneic mice with tumor-antigen-reconstituted liposomes were investigated. Liposomes were prepared from a crude butanol extract (CBE) of BALBRVD leukemia cells and egg phosphatidylcholine
The nature of the interaction of the simian virus 40 (SV40) transforming protein, large tumor antigen (T-ag), with the plasma membrane of transformed cells is not well understood. We report here that SV40 plasma-membrane-associated large tumor antigen (pmT-ag) can be solubilized by using
Treatment of whole viable MCA-F murine sarcoma cells from syngeneic female C3H/HeJ mice with a single-phase solution of 2.5% (vol/vol) 1-butanol yielded a crude membrane protein extract without loss of cell viability. 1-Butanol-extracted cells were capable of in vitro proliferation. Variations in
Successful treatment of superficial bladder cancer using nonspecific immunotherapy with Bacillus Calmette-Guerin (BCG) has been well documented. Investigation of two potential tumor-specific immunotherapeutic agents using a murine transitional-cell carcinoma model (MBT-2) is reported. The survival
BACKGROUND
Epidemiological and laboratory studies support the hypothesis that several plant components influence prostate carcinogenesis and holds promise for disease prevention. Previously we reported that Nexrutine (bark extract from Phellodendron amurense) inhibits proliferation of prostate
Solanum lyratum Thunb (Solanaceae) has been widely used for cancer as a folk remedy in Chinese traditional medicine. In this study, the main active fraction n-butanol extract from S. lyratum (BESL) was evaluated for the therapeutic efficacies on mice transplantable tumor and immunomodulatory
Gastric cancer (GC) ranks as the third leading cause of cancer-related mortality worldwide, and approximately 42% of all cases diagnosed each year worldwide are diagnosed in China. A large number of clinical applications have revealed that Trametes robiniophila Μurr. (Huaier) exhibits an anti-tumour
Lung cancer is the most common cause of cancer-related deaths in humans worldwide. There is strong evidence that the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) play an important role in
The extrahepatic UDP-glucuronosyltransferase 1A10 (UGT1A10) is a phase II metabolizing enzyme that is active against a number of potent carcinogens. In the present study, UGT1A10 was examined for activity against 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), the major procarcinogenic
