PURPOSE: Understanding growth regulation in hormone-refractory prostate cancer may provide avenues for novel treatment interventions. This study was conducted to characterize the expression of the receptor (FSHR) for follicle-stimulating hormone (FSH) in androgen-independent prostate cancer cell lines and in human malignant prostate tissues. MATERIALS AND METHODS: Western blotting, immunohistochemistry (IHC), and flow cytometric analysis were used to study the expression of FSHR. The effect of FSH on cell growth and clonogenicity was studied using proliferation and clonogenic assays. RESULTS: Immunohistochemistry revealed expression of FSH in PC3 and Du145 cells. FSHR was identified in PC3 and Du145 cells, as well as in human adenocarcinoma of the prostate. The specificity of the FSHR detected on prostate cancer tissues or cells by IHC and Western blotting was confirmed by preabsorbing the antibodies with the immunizing antigens. Stimulation of these hormone-refractory cells with FSH triggered a proliferative response in vitro, suggesting that the receptor is biologically active. CONCLUSION: Hormone-refractory prostate cancer cells express FSH and biologically active FSHR. Our results suggest that FSHR and its ligand may play a role in the regulation of the growth of hormone-refractory prostate cancers.

Sexually dimorphic expression of sst1 and sst2 somatostatin receptor subtypes in the arcuate nucleus and anterior pituitary of adult rats.

The pattern of growth hormone (GH) secretion and rate of somatic growth are markedly sexually dimorphic, but the underlying neuroendocrine mechanisms are far from clear. In the present study, we tested the hypothesis that the sexual dimorphism of GH secretion may be due to gender-related differences in the transduction of somatostatin's actions in brain and/or pituitary. To accomplish this, we compared the distributional pattern and level of expression of two somatostatin receptor subtypes, sst1 and sst2, in the brain and pituitary of adult male and female rats by in-situ hybridization using 35S-labelled antisense riboprobes. In the brain, the hybridization pattern and labelling density of sst1 and sst2 mRNA-expressing cells, as revealed by computer-assisted image analysis, in areas including the cerebral cortex, medial habenula (MHb) and ventromedial hypothalamic nucleus (VMN), were similar in male and female rats. In contrast, there was a marked sex-related difference in sst1 expression in the arcuate nucleus of the hypothalamus; both the number and labelling density of sst1 mRNA-expressing cells were two- to threefold greater in males than in females and this significant increase was homogenous throughout the rostrocaudal extent of the nucleus. No gender-related differences in arcuate sst2 mRNA levels were found. At the level of the anterior pituitary, the labelling density of sst2 mRNA in males was significantly higher than that of females. No sex-related difference in pituitary sst1 mRNA was observed. These results demonstrate a sexual dimorphism in the expression of two somatostatin receptor subtypes, sst1 and sst2, at the level of the arcuate nucleus and anterior pituitary, respectively. Such dimorphism suggests a differential involvement of sst1 and sst2 in GH regulation with respect to gender, and may imply roles for sst2 and sst1 in transducing somatostatin's actions on pituitary somatotrophs and GH-releasing hormone-containing arcuate neurones, respectively, to generate the lower basal and higher GH pulse levels characteristic of the male rat.

Persistent effects of prenatal, neonatal, or adult treatment with flutamide on the hypothalamic-pituitary-adrenal stress response of adult male rats.
McCormick CM, Mahoney E.

To explore the role of androgens in early development on adult hypothalamic-pituitary-adrenal (HPA) function in males, we administered flutamide or vehicle injections: (1) to pregnant dams on embryonic days 15-20; (2) to neonatal pups on days 0-5; or (3) to adults on days 55-60. At approximately 70 days of age, trunk blood was collected to determine corticosterone levels (1) upon removal from the home cage, (2) immediately after 30 min of restraint stress, or (3) 60 min after return to home cage following the stressor. Flutamide treatment resulted in higher basal levels of testosterone and stress levels of corticosterone compared to vehicle treatment, and there was no interaction of treatment with age at time of treatment. This suggests that testosterone is less effective at inhibiting HPA function in flutamide-treated males. In addition, prenatally treated males had higher stress levels of corticosterone than neonatally and adult-treated males, regardless of the type of treatment. There were no differences in CBG levels among the groups. The results suggest that, in males, flutamide treatment has a long-lasting effect on HPA function. These results are consistent with our previous research on neonatally gonadectomized males and the hypothesis of organizational effects of sex hormones on HPA function. 1999 Academic Press.

1,25 dihydroxyvitamin D3 enhances the calcium response of keratinocytes.

The steroid hormone 1,25 dihydroxyvitamin D3 (1,25(OH)2D3) regulates cell proliferation and differentiation. Intracellular calcium (Cai) concentrations play a crucial role in these events. From our previous studies, we have demonstrated a calcium receptor (CaR) in keratinocytes which appears to regulate the initial release of Cai from intracellular stores in response to extracellular calcium (Cao) and so is likely to participate in the differentiation process. In this study, we determined whether the ability of 1,25(OH)2D3 to enhance Ca++ -induced differentiation was mediated at least in part through changes in the CaR. Keratinocytes were grown in keratinocyte growth medium (KGM) with 0.03 mM, 0.1 mM, or 1.2 mM Ca and treated with 10(-8) M 1,25(OH)2D3 till harvest after 5, 7, 14, and 21 days. CaR mRNA levels were quantitated by polymerase chain reaction. The results were compared to the ability of 1,25(OH)2D3 to enhance calcium-stimulated increases in Cai. In cells grown in 0.03 mM Ca, the CaR mRNA levels decreased with time. 1,25(OH)2D3 stimulated the levels at 5 days and prevented the falloff over the subsequent 16 days. On the other hand, in cells grown in 0.1 or 1.2 mM Ca, the message levels remained high, and 1,25(OH)2D3 had no further effect. To study the functional relationship, we harvested cells after 5 and 7 days in culture following a 24 h treatment with 1,25(OH)2D3 or vehicle to measure the Cai response to 2 mM Cao. The preconfluent cells grown in 0.03 mM Ca showed a nearly twofold increase in the Cai response to Cao when pretreated with 1,25(OH)2D3, whereas the confluent cells and those grown in 1.2 mM Ca showed no enhancement by 1,25(OH)2D3. Studies with 45Ca influx into keratinocytes revealed that 1,25(OH)2D3 enhanced the influx in preconfluent and confluent cells when grown in KGM containing 0.03 mM Ca but not in cells grown in 1.2 mM calcium. We conclude that 1,25(OH)2D3 maintains the CaR mRNA levels in cells grown in 0.03 mM Ca, thus maintaining their responsiveness to Cao and so ensuring their ability to differentiate in response to the calcium signal.

Parathyroid hormone-related protein (PTH-rP)-associated hypercalcemia in a patient with an atypical chronic lymphocytic leukemia.

We describe a patient with an atypical chronic lymphocytic leukemia (CLL) of the mixed cell type with a hypercalcemia due to parathyroid hormone-related protein production by the malignant B cells. On regard of the elevated serum calcium level without overt lytic bone lesions we found elevated serum levels of PTH-rP and demonstrated the presence of PTH-rP on the malignant lymphocytes. PTH-rP-related hypercalcemia in CLL is very rare. The role in PTH-rP in humoral hypercalcemia of malignancy is discussed.

There are a number of approaches to hair loss problems.
Hair Million is an herbal alternative. It is a formula made of traditional, edible herbs
and has been anecdotally demonstrated the efficacy to ward off hair loss
problems.
There is no singular medical or alternative cure for hair loss since the
biology of hair growth is a highly complicated phenomenon.
It is unknown how Hair Million stops hair loss,
and promotes hair restoration.
The advantages of Hair Million over other approaches are, firstly, Hair Million is comparatively inexpensive,
and secondly, it is made only of traditionally used safe and healthy herbs that promote hair growth
according to Chinese pharmacopoeia. In addition, Hair Million is cardiotonic, meaning that Hair Million consists of herbs
that strengthens your heart, according to Chinese medicine. There is an interesting research paper which correlates baldness
to heart diseases: people with alopecia or hair loss
problems are significantly more likely to develop heart attacks.
