Differential display was used to identify novel androgen-regulated genes in the human prostatic adenocarcinoma cell line LNCaP. A 322-base pair cDNA fragment that was consistently induced by the synthetic androgen R1881 revealed 100% homology with the human phosphatidic acid phosphatase type 2a isozyme very recently reported by Kai et al. (PAP-2a; Kai., M., Wada, I., Imai, S.-i., Sakane, F., an...

The current drugs against sleeping sickness are derived from cancer chemotherapeutic approaches. Herein, we aimed at evaluating the in vitro effect of alcoholic extracts of Artemisia annua (AMR), Rumex abyssinicus (RMA), and Catha edulis Forsk (CEF) on proliferation/viability of 1321N1 astrocytoma, MCF-7 breast cancer, THP-1 leukemia, and LNCaP, Du-145, and PC-3 prostate cancer cells and on Try...

Prostate cancer is the second leading cause of death in men in western countries and is usually treated by surgery and/or radiotherapy. More recently, hyperthermia has been introduced into clinical trials investigating a possible effect in the first-line treatment of prostate cancer. However, the molecular mechanisms of hyperthermia are not completely understood. In this study, we investigated ...

Despite remarkable advances in the therapy and prevention of prostate cancer it is still the second cause of death from cancer in industrialized countries. Many therapies initially shown to be beneficial for the patients were abandoned due to the high drug resistance and the evolution rate of the tumors. One of the prospective therapeutical agents even used in the first stage clinical trials, 1...

Background: Prostate cancer (PCa) is the second most common in men worldwide and few studies have been reported investigating effects of homeopathic therapy on PCa. Tarantula cubensis alcoholic extract (TCAE), used veterinary medicine as there are various about therapeutic efficacy TCAE treating different diseases. However, treatment limited.
 Aim: It was aimed to investigate which prostat...

Androgen deprivation therapy (ADT, surgical or chemical castration) is the mainstay treatment for metastatic prostate cancer (PCa); however, patients ineluctably relapse despite extremely low androgen levels. This evolution of PCa indicates its lethal progression. In this study, to mimic the traits of clinical PCa progression in vitro, we investigated the alterations in the cell biological char...

Lithocholic acid (LCA) is a secondary bile acid that is selectively toxic to human neuroblastoma, breast and prostate cancer cells, whilst sparing normal cells. We previously reported that LCA inhibited cell viability and proliferation and induced apoptosis and necrosis of androgen-dependent LNCaP and androgen-independent PC-3 human prostate cancer cells. In the present study, we investigated t...

recently, specific attention has been paid to aptamers, short dna or rna, as a tool for cancer diagnosis and therapy. in the present study mcs nanogels were prepared by myristate: chitosan at 1:9 ratio and were characterized by several techniques. a selected ssdna aptamer(apt) capable of detecting lncap cells was linked to myristilated chitosan nanogels (apt-mcs) by glutaraldehyde and loaded wi...

background: prostate cancer is one of the leading causes of cancer deaths among men. new gene expressed in prostate (ngep), is a prostate-specific gene expressed only in normal prostate and prostate cancer tissue. because of its selective expression in prostate cancer cell surface, ngep is a potential immunotherapeutic target. to target the ngep in prostate cancer, it is essential to investigat...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...
