Endocrine studies in male pseudohermaphroditism in childhood and adolescence.
Savage MO, Chaussain JL, Evain D, Roger M, Canlorbe P, Job JC.
The clinical and endocrine features of fifty cases of male pseudohermaphroditism and XY karyotype aged from 6 months to 20 years have been studied. Thirty-two subjects were pre-pubertal and eighteen, of whom ten developed gynaecomastia, were pubertal. A definite aetiology was established in 12%. 4% had deficient testosterone biosynthesis and 8% mixed gonadal dysgenesis. In the remaining 88% an aetiology of androgen unresponsiveness at the target areas is suggested. Hormonal investigations in these subjects showed that before puberty basal plasma testosterone and oestradiol were slightly but significantly elevated, whereas testosterone response to stimulation with human chorionic gonadotrophin was significantly diminished. In the pubertal subjects basal plasma testosterone, oestradiol, serum binding capacity of testosterone-oestradiol binding globulin and basal plasma LH were significantly elevated. These hormonal features in pubertal or post-pubertal male pseudohermaphrodites appear to be characteristic of androgen unresponsiveness. The presence in addition of elevated basal plasma testosterone and oestradiol in the pre-pubertal subjects suggest that some of these findings may be presented from early childhood.

[Comparison of plasma testosterone (T), androstenedione (A) and dhea variations after metopirone in 10 normal and 12 hirsute women (author's transl)]
[Article in French]
Darsy P, Forest MG, de Peretti E, Bertrand J, Tourniaire J.
Plasma testosterone; androstenedione and DHA were measured by radio-immunoassay before (J1) under (J2) and 24-hour after (J3) oral metyrapone (4,5 g) in 10 normal and 12 hirsute women. Although individual values were dispersed, hirsute women, as a group, had significantly higher values at each time for each steroid. Hirsute women with normal basal T had normal T and A values for J1, J2, J3; while these with elevated basal T had elevated T and A value for all samples. Plasma DHEA was elevated in the two groups, before, under and after metopirone.

Androgen, estrogen, and progesterone by a lipid cell tumor of theovary.
Bonaventura LM, Judd H, Roth LM, Cleary RE.
In a 64-year-old woman with a virilizing lipid-cell tumor of the left ovary, serum progesterons, androgens, estrogens, and cortisol levels in the peripheral and ovarian veins were measured. Although virilization was the only symptom of hormone production by the tumor in this patient, endocrine studies showed that several steroids were secreted by this neoplasm. Of the steroids measured, androstenedione was the principal secretory product. Pregnenolone, 17-hydroxypregnenolone, 17-hydroxyprogesterone, dehydroepiandrosterone, and testosterone were also secreted, but in quantities which were one third to one sixth the amount of androstenedione. The tumor's pattern of hormone secretion was similar to patterns of steroid production by ovarian stromal cells found in previously reported in vitro studies. This case and a review of the literature demonstrate that androstenedione appears to be the predominant secretory product of lipid cell tumors, whereas testosterone is the predominant secretory product of hilus cell tumors.

The expression of the ADAMs proteases in prostate cancer cell lines and their regulation by dihydrotestosterone.

The ADAMs are a multi-functional gene family, some of which have been shown to play a role in diverse biological processes such as fertilization, myogenesis, neurogenesis and the activation of growth factors/immune regulators such as TNF-alpha. So-named because they possess both A Disintegrin And Metalloprotease domain, the ADAMs have potential implications for the metastasis of human tumour cells via cell adhesion and protease activities. However, no studies have yet comprehensively examined the expression or regulation of ADAMs in solid tumours. Therefore, the aim of this study was to examine the expression of the ADAMs in human prostate cancer cell lines and to examine their possible regulation by androgen, a primary hormonal regulator of prostate cancer cell proliferation and metastasis. Applying RT-PCR, ADAM-9, -10, -11, -15 and -17 mRNA expression was found in the androgen-dependent prostate cancer cell lines, LNCaP and ALVA-41 and the androgen-independent cell lines, DU-145 and PC-3. Northern blotting of LNCaP cell total RNA revealed transcripts for ADAM-9 (3.8 kb), ADAM-10 (4.4, 3.2 and 0.54 kb), ADAM-15 (3 kb) and ADAM-17 (4 and 2.6 kb). ADAM-11 transcript was not detected by Northern blotting possibly due to low levels of ADAM-11 mRNA expression. This is the first report of ADAM expression in prostate cancer cell lines. Since androgens are implicated in prostate cancer cell growth and maintenance, the regulation of ADAMs by dihydrotestosterone (DHT) was investigated in the androgen-dependent cell line LNCaP. It was shown by quantitative RT-PCR using continuous fluorescence monitoring that ADAM-10 mRNA expression was regulated in a bell shaped, dose-dependent manner by DHT. Maximum stimulation was observed at 1.0 nM DHT (5-fold significant increase). For ADAM-9 mRNA, a significant upregulation was found at 1.0 and 10 nM (1.5-1.7-fold increase). In contrast, ADAM-17 mRNA, was significantly inhibited at 0.1 and 1.0 nM (1.7-fold decrease). This is the first report, to our knowledge, illustrating hormonal regulation of ADAM mRNA. The novel data described here also provide a strong stimulus to the development of specific quantitative and functional assays for particular ADAMs. These assays, which are not yet available, are required to enable subsequent investigation, both in vitro and in vivo, of the specific roles of each ADAM in prostate cancer cell proliferation, cell motility and invasion.

Hair loss is a problem in modern soceity. Examining the factors of hair growth may
shed light on how hair loss might occur.
How long can hair grow before it stops growing eventually if it does?
Given that the hair growth rate is quite uniform and constant, somewhere between 0.3-0.5 millimeters per day, it's believed that the length of anagen, the growth phase, differs among individuals, and this is the major determinant to the maximum hair length. For some individuals, anagen may last ten years. Of course the length of the anagen is governed by genes, and the genetic background of the individuals. Non-genetic factors such as nutritional condition, weather, seasonal changes (hair may grow a bit faster during winter), taking medications, health condition may of course influence the rate of
hair growth as well as
hair loss.
The shape of the hair, straight or curly, is dependent on the shape of the follicle. A circular or round hair follicle would generate straight hair, while the follicle with oval or elliptical shapes (in its cross-section) would produce a curly hair.
DHEA is a natural hormone, and it is produced in our body by the adrenal glands.
DHEA has been suggested to provide numerous potential benefits. DHEA (or dehydroepiandrosterone) is converted into androgens (male hormones)
or estrogens (female hormones) in the cells.
