BACKGROUND So far, the anticancer action of pine tree extracts has mainly been shown for the species distributed widely around the Asian countries. OBJECTIVE Therefore, this study was performed to examine the potential cytotoxicity of Scots pine (Pinus sylvestris L.) native also to the European

m-Chloroperoxybenzoic acid (CPBA) was tested for its ability to induce the ornithine decarboxylase (ODC) marker of skin tumor promotion. In contrast to benzoyl peroxide, dicumyl peroxide, and 2-butanol peroxide, 5 mg of CPBA applied twice at a 72-h interval induce ODC activity at least as much as 3

m-Chloroperoxybenzoic acid (CPBA),which induces ornithine decarboxylase activity as much as 12-O-tetradecanoylphorbol-13-acetate (TPA), was tested for its ability to induce DNA synthesis, hydroperoxide (HPx) production, and tumor promotion in mouse epidermis in vivo. After an early inhibition, CPBA

BACKGROUND Oligomeric proanthocyanidin complexes (OPC) are extracted from grape seeds or maritime pine bark and have been used for enhancement of capillary stability and lymphatic drainage. Since a role for OPC in cancer prevention was postulated, we asked whether they have an effect on prostate

Pinecones from Pinus koraiensisSiebold & Zucc. (Pinaceae), which have historically been treated as an undesired waste by-product in the processing of seeds, have recently been shown to contain ingredients with potent biological activities, such as polyphenols exhibiting antitumor activity. With this

Pinecone polyphenols are bioactive dietary constituents that enhance health and help prevent and treat cancer through improving antioxidant and immunoregulatory activities. This study was designed to investigate the antitumor, antioxidant and immunoregulatory activities of the 40% ethanol eluent of

The side effects and inefficiency of paclitaxel (PTX) in clinic have been became a major problem for cancer chemotherapy. The local drug delivery constructed by injectable hydrogel has been suggested as the alternative due to its superior properties such as tumor selectivity, minimally invasive

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

The intravenous or the oral administration of a pine cone extract of Pinus parviflora Sieb et Zucc (Fr VI) and the related synthetic agent (DHP-FA) to lactating SHN mice prevented an increase of milk levels of mouse mammary tumour virus (MMTV) from day 7 to day 14 of lactation. Furthermore, Fr VI

A lignin-related cone extract of pine (Pinus parviflora Sieb et Zucc) (FrVI) or a synthetic lignin (DHP-FA) (175 micrograms/0.1 ml 0.9% NaCl solution) was injected intravenously to SHN mice bearing spontaneous mammary tumours three cycles each with consecutive 3 days of treatment and 4 days of

Eight heterogeneous tannin samples (HTSs) extracted from various tree/shrub leaves of African and Himalayan origin were tested topically for their ability to inhibit the biomarkers of tumor promotion in mouse skin in vivo. HTS2 (from Dichostachys cinerea) and HTS6 (from Cassia sieberiana)

Talc and poor diet have been suggested to increase the risk of developing ovarian cancer; which can be reduced by a diet rich in fruit and vegetables. Talc is ubiquitous despite concern about its safety, role as a possible carcinogen and known ability to cause irritation and inflammation. It was

BACKGROUND The essential oil of Pinus koraiensis (EOPK) is biologically active compound obtained from the leaves of P. koraiensis. The goal of this study was to investigate the anti-cancer mechanism of EOPK in HCT116 colorectal cancer cells. METHODS HCT116 cell proliferation was assessed by

The previous study evaluated the antitumor activity and the underlying mechanism of the purified polyphenols from pinecones of Pinus koraiensis (PPP-40) using a tumor-bearing S180 mice model. This study was designed to evaluate the protective effects of PPP-40 on spleen tissues of S180 mice in vivo.

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
