PTEN is one of the most frequently mutated genes in human cancers. The frequency of PTEN alterations is particularly high in endometrial carcinomas. Loss of PTEN leads to dysregulation of cell division, and promotes the accumulation of cell cycle complexes such as cyclin D1-CDK4/6, which is an important feature of the tumour phenotype. Cell cycle proteins have been presented as key targets in the treatment of the pathogenesis of cancer, and several CDK inhibitors have been developed as a strategy to generate new anticancer drugs...

BACKGROUND: Letrazole is an aromatase inhibitor, which is useful in ovulation induction. However, evidence on its efficacy over clomiphene citrate, which is the first of drug used for therapy of anovulation, is insufficient in Indian patients. AIMS: To compare the efficacy of letrozole and clomiphene citrate in attaining optimal follicular growth. MATERIALS AND METHODS: The study was conducted in the infertility clinic of Mahatma Gandhi Medical College and Research Institute, Pondicherry, India from June 2008 to December 2009...

OBJECTIVE: To identify pre or post processing semen analysis parameters that may be predictive of successful pregnancy in couples with male factor infertility undergoing intra uterine insemination (IUI). To evaluate the pregnancy rate based on ovulation inducing agent in couples with male factor infertility per the 2010 world health organization criteria treated with IUI. STUDY DESIGN: This retrospective study was performed at Stanford University medical center...

Pharmacists who are involved with patients and physicians have a tremendous opportunity to serve in the realm of prostate cancer, and there are numerous compounding opportunities. For example, compounded testosterone gels can help keep testosterone levels in the mid to upper range with proper dosing and patient counseling. Also, estradiol levels can be held in check or lowered by compounding aromatase-inhibitors such as anastrazole or letrazole into the lower doses that men require, rather than their more potent versions for female patients...

A new multidentate ligand (L) has been synthesized by the controlled condensation of L-glutamic acid with formaldehyde and ethylenediamine. Cu(II) and Ru(III) metal ion complexes of the synthesized ligand have also been prepared. The ligand and the metal complexes were purified by chromatography and characterized by spectroscopy and other techniques. Molar conductance measurements suggested ionic nature of the complexes. The ligand and the complexes are soluble in water with quite good stabilities; essential requirements for effective anticancer drugs...

The successful translation of the scientific principles of targeting the breast tumour oestrogen receptor (ER) with the nonsteroidal anti-oestrogen tamoxifen and using extended durations (at least 5 years) of adjuvant therapy, dramatically increased patient survivorship and significantly enhanced a drop in national mortality rates from breast cancer. The principles are the same for the validation of aromatase inhibitors to treat post-menopausal patients but tamoxifen remains a cheap, life-saving medicine for the pre-menopausal patient...

PURPOSE: To evaluate the effect of adjunctive letrazole or clomiphene in IVF stimulation protocols. METHODS: A retrospective analysis of high dose GnRH antagonist IVF cycles (450-600 IU of gonadotropins) that have met poor responder criteria. Selected consecutive cycles in same patients differed solely in presence or absence of adjunctive clomiphene or letrazole. RESULTS: Supplementation with clomiphene citrate in poor responders showed significant improvements (p < 0...

The main purpose of this research was to study the impact of hormonotherapy on changes of the lipid metabolism in patients with breast cancer. 451 breast cancer patients were under investigation. Depending on the treatment method, all patients were divided into four groups. The first group was composed of 117 patients who received hormonotherapy consisting of tamoxifen 20 mg/day; the second group was composed of 115 patients who received Toremifen 60 mg/day; The third group was composed of 106 patients who received Toremifen 240 mg/day; The fourth group consisted of 113 patients who received Letrozol 2,5 mg/day...

INTRODUCTION: Since the advent of Highly Active Anti-Retroviral Therapy (HAART), men with HIV experience good quality of life and expect to have normal sexual function. However, it appears that men infected with HIV commonly complain of sexual problems. There is evidence that men on HAART develop low sexual desire that is associated with raised estradiol levels. It has been postulated that abnormal metabolism seen in this group of men increases the aromatization of testosterone to estradiol...

BACKGROUND: Acrometastases are very rare and have been identified in only a few cases on the foot. At the onset, they might be misdiagnosed as arthritis. CASE REPORT: A 59-year-old woman with isolated metastasis to the talus, originating from breast carcinoma was treated by radiotherapy, letrazole, and intravenous bisphosphonates. RESULTS: The review of the literature revealed that this is the first case of an isolated metastasis to the bone of talus from a breast carcinoma, while there are a few cases originating from other organs...

Aromatase (cytochrome P450 19, CYP19, P450arom) is the enzyme responsible for the production of estrogens, hormones critical for development and reproduction. Aromatase was sequenced from a white-sided dolphin (Lagenorhynchus acutus) ovary, transiently transfected into HEK 293 cells, and the expressed protein was characterized for aromatase activity in the presence of androstenedione and testosterone and after exposure to the aromatase inhibitor letrazole. The Kms for androstenedione and testosterone were 63...

The formation of estrogens from androgens in all vertebrates is catalyzed by the "aromatase" complex, which consists of a membrane bound P(450) enzyme, P(450) aromatase (which binds the androgen substrate and inserts an oxygen into the molecule), and a flavoprotein (NADPH-cytochrome P450 reductase). Among vertebrates, the two major sites of aromatase expression are the brain and gonads. Given the importance of estrogen in reptile sex determination, we set out to examine whether P450arom was involved in the initiation and/or stabilization of sex determination in turtles...

Treatment of male rats at birth with an aromatase inhibitor (Letrazole), followed by adult gonadectomy GDX, led to an increase in dendritic spine density on ventromedial hypothalamic neurons (VMN) when treated with estrogen as compared to a decrease when vehicle animals were given estrogen. In contrast, estrogen-treatment increased dendritic spine density on CA1 pyramidal neurons regardless of neonatal treatment. In addition, in CA1 there was a significant difference between the two estrogen groups. These results suggest that estrogen induction of dendritic spines in the VMN and CA1 is dependent on organizational effects of gonadal steroids...
