alpha-Chlorohydrin inhibits glyceraldehyde-3-phosphate dehydrogenase in multiple organs as well as in sperm. (1/35)

Numerous studies have documented inhibitory effects of alpha-chlorohydrin (ACH) on glyceraldehyde-3-phosphate dehydrogenase (G3PDH) activity in spermatozoa. A sperm-specific G3PDH isoform has been described. The possibility that ACH may inhibit G3PDH in cell types other than sperm was investigated in this work. In addition, the onset of ACH-induced epididymal toxicity was described. Changes to epididymal histology occurred 6 h following a single dose of ACH (50 mg/kg po) and were confined to the proximal initial segment. By 24 h, no epithelial cells lined the basement membrane of that region. Three h after ACH administration (50 mg/kg po), G3PDH activity was significantly decreased in sperm (85%) as well as in kidney (31%), liver (49%), and epididymis (35%). Enzyme activity remained inhibited at 6 and 24 h. G3PDH was immunolocalized in the epididymis and staining was highest in the efferent ducts and initial segment as well as in smooth muscle. Since G3PDH is a microtubule-associated protein and microtubule-dependent endocytosis occurs in the epididymis, beta-tubulin was also immunolocalized. beta-tubulin densely stained the apical region of initial segment and caput epithelial cells. Disruption of beta-tubulin immunostaining correlated with the localization and onset of the lesion. Co-localization of G3PDH and beta-tubulin immunostaining was not observed although both antibodies most densely stained the initial segment. Our data indicate that histologic changes to the proximal initial segment of the epididymis occur rapidly, but subsequent to G3PDH inhibition. Moreover, ACH inhibition of G3PDH is not confined to sperm, although the sperm enzyme is most sensitive to inhibition.  (+info)

Phagocytosis of spermatozoa by the epithelial cells of the ductuli efferentes after epididymal obstruction in the rat. (2/35)

The effects of ligation of an isolated loop of the ductus epididymidis in the region of the caput were compared with those of the exfoliative lesion of the epididymis that follows administration of alpha-chlorhydrin to rats. Electron micrographs of the ductuli efferentes in both cases revealed early phagocytosis of apparently normal spermatozoa by the epithelial cells, followed at later intervals by invasion of macrophages and intraluminal phagocytosis. It is concluded that epithelial spermiophagy is a consequence of obstruction, whether mechanically or chemically induced.  (+info)

Purification and properties of arylsulphatase A from rabbit testis. (3/35)

Rabbit testis arylsulphatase A was purified 140-fold with a recovery of 20% from detergent extracts of an acetone-dried powder by using DE-52 cellulose column chromatography, gel filtration on Sephadex G-200 and preparative isoelectric focusing. The purified enzyme showed one major band with one minor contaminant on electrophoresis in a 7.5% (w/v) polyacrylamide gel at pH8.3. On sodiumdodecyl sulphate/polyacrylamidegel electrophoresis, a single major band was observed with minor contaminants. The final preparation of enzyme was free from general proteolytic, esterase, hyaluronidase, beta-glucuronidase and beta-galactosidase activities. Rabbit testicular arylsulphatase A exists as a dimer of mol.wt. 110000 at pH7.1. At pH5.0 the enzyme is a tetramer of mol.wt. 220000. Arylsulphatase A appears to consist of two identical subunits of mol.wt. 55000 each. The highly purified enzyme has pI4.6. The enzyme hydrolyses p-nitrocatechol sulphate with Km and Vmax, of 4.1 mM and 80nmol/min respectively, but has no activity toward p-nitrophenyl sulphate. The pH optimum of the enzyme varies with the incubation time. By applying Sephacex G-200 chromatography and preparative isoelectric focusing, one form of enzyme was obtained. The enzyme has properites common to arylsulphatase A of other sources with respect to the anomalous time-activity relationship, pI, inhibition by PO42-, SO32- and Ag+ ions and substrate affinity to p-nitrocatechol sulphate. However, the enzyme shows the temperature optimum of arylsulphatase B of other species.  (+info)

Investigation of usefulness of sperm analyses in dogs for male fertility study. (4/35)

The usefulness of sperm analyses in dogs, including sperm motion analysis, was investigated. Sperm motion analysis was performed with the CellSoft-4000 computer-assisted sperm analysis (CASA) system. First, we examined the conditions for preservation of optimal semen quality. We found that sperm retained more of their motility at 4 degrees C than at 37 degrees C. Secondly, we observed sperm motion, concentration and morphology in dog semen continuously for 11 weeks. We collected semen samples during the test period, and the samples retained sperm motion, concentration and morphology. Finally, we administrated alpha-chlorohydrin, which decreases rodent sperm motion, at a single oral dose of 100 mg/kg or 150 mg/kg to dogs. Sperm motion was inhibited immediately after alpha-chlorohydrin treatment, and recovered after 2 weeks. None of the experimental animals were sacrificed in the above-mentioned examinations. We thus confirmed that sperm analyses including motion analysis in dogs are useful in male fertility studies.  (+info)

The effects of alpha-chlorohydrin on the composition of rat and rabbit epididymal plasma: a possible explanation of species difference. (5/35)

The relationship between the antifertility effect of alpha-chlorohydrin and changes in composition of luminal plasma from the cauda epididymidis of rats and rabbits has been investigated. At each dose regimen studied, the fertilizing capacity of rats treated with alpha-chlorohydrin was reduced to zero. The levels of sodium, potassium, glycerylphosphorylcholine (GPC), acid phosphatase and alkaline phosphatase in epididymal plasma were not markedly affected by drug treatment. The most noticeable change was a considerable increase in the concentration of lactic dehydrogenase (LDH) at all dose levels and of glutamic-oxaloacetic transaminase (GOT) after 7 days of treatment with 8 and 16 mg/kg. The effect of cold shock on the composition of epididymal plasma showed that LDH and GOT are, at least in part, derived from spermatozoa. In contrast, alpha-chlorohydrin did not have an antifertility action in the rabbit, and the only notable change in the compositon of epididymal plasma was an increase in the level of GPC. These results provide evidence that, in the rat, alpha-chlorohydrin or a metabolite primarily exerts its antifertility effect by a direct action on the spermatozoa, whilst in the rabbit a barrier may exist to the entrance of the drug into the lumen of the epididymal duct.  (+info)

Inhibition of bull and rabbit sperm enzymes by alpha-chlorohydrin. (6/35)

High concentrations of alpha-chlorohydrin were found to inhibit hyaluronidase, beta-glucuronidase, and aryl sulphatases in bull and rabbit spermatozoa, but not acrosin and neuraminidase. Preincubation of the enzyme and alpha-chlorohydrin was essential to achieve the maximum inhibition which was irreversible.  (+info)

Fertilizing ability in vivo and in vitro of spermatozoa of rats and mice treated with alpha-chlorohydrin. (7/35)

The fertilizing ability of epididymal spermatozoa from rats and mice treated for 3 or 4 or 9 or 10 days with various doses of alpha-chlorohydrin was tested in vitro, and in vivo by intrauterine insemination. The minimum doses (per kg/day) needed to affect fertilization significantly were: rat, in vitro, 8-8 mg for 3 or 4 days, 4-4 mg for 4 days and 2-7 mg for 9 or 10 days; in vivo, 4-4 mg for 3 or 4 days and 2-7 mg for 9 or 10 days: mouse, in vitro, 4-4 mg for 3 days and 13-3 mg for 9 days; in vivo, 44-2 mg for 3 days and 26-5 for 9 days. Rats were infertile for at least 18 days after receiving 44-2 mg alpha-chlorohydrin/kg/day for 3 days, but fertilizing ability, tested in vivo and in vitro, was restored 10-11 days and 15-18 days, respectively, after daily treatment with 11-1 mg alpha-chlorohydrin/kg for 3 days.  (+info)

Resolution and some properties of enzymes involved in enantioselective transformation of 1,3-dichloro-2-propanol to (R)-3-chloro-1,2-propanediol by Corynebacterium sp. strain N-1074. (8/35)

During the course of the transformation of 1,3-dichloro-2-propanol (DCP) into (R)-3-chloro-1,2-propanediol [(R)-MCP] with the cell extract of Corynebacterium sp. strain N-1074, epichlorohydrin (ECH) was transiently formed. The cell extract was fractionated into two DCP-dechlorinating activities (fractions Ia and Ib) and two ECH-hydrolyzing activities (fractions IIa and IIb) by TSKgel DEAE-5PW column chromatography. Fractions Ia and Ib catalyzed the interconversion of DCP to ECH, and fractions IIa and IIb catalyzed the transformation of ECH into MCP. Fractions Ia and IIa showed only low enantioselectivity for each reaction, whereas fractions Ib and IIb exhibited considerable enantioselectivity, yielding R-rich ECH and MCP, respectively. Enzymes Ia and Ib were isolated from fractions Ia and Ib, respectively. Enzyme Ia had a molecular mass of about 108 kDa and consisted of four subunits identical in molecular mass (about 28 kDa). Enzyme Ib was a protein of 115 kDa, composed of two different polypeptides (about 35 and 32 kDa). The specific activity of enzyme Ib for DCP was about 30-fold higher than that of enzyme Ia. Both enzymes catalyzed the transformation of several halohydrins into the corresponding epoxides with liberation of halides and its reverse reaction. Their substrate specificities and immunological properties differed from each other. Enzyme Ia seemed to be halohydrin hydrogen-halide-lyase which was already purified from Escherichia coli carrying a gene from Corynebacterium sp. strain N-1074.  (+info)

In these experiments, TG was used to deplete Ca2+ stores in cells maintained in nominally Ca2+-free extracellular solution. Addition of Ca2+ to the extracellular solution resulted in SOCE-mediated increase in [Ca2+]c (cytosolic Ca2+ concentration) followed by formation of an elevated [Ca2+]c plateau (Figure 4). Addition of InsP3-producing secretagogue ACh reversibly decreased the amplitude of the plateau (Figure 4A, n=465). Using the Mn quench technique [20] we also observed a small (13±2%) but statistically significant inhibition of the influx by 300 nM ACh (Supplementary Figure S5 available at http://www.BiochemJ.org/bj/436/bj4360231add.htm, n=145 cells in ACh-treated group and n=139 cells in control group). Caffeine (10 mM), which in PACs very efficiently blocks InsP3-induced Ca2+ responses [21] has no effect on its own (Figure 4B, n=169), but it partially reversed the ACh-induced reduction of the plateau (Figure 4C, n=168). These experiments suggest that activation of IP3Rs has a mild ...
A comprehensive disposition and metabolism study of epichlorohydrin (ECH) has not been previously reported. In this study, male Fischer 344 rats were dosed (6 mg/kg) orally with [2-14C]ECH (98% radiochemically pure) as an aqueous solution and killed after 3 days. Approximately 38% of the radioactive dose was exhaled as CO2, 50% was excreted as metabolites in the urine, and 3% was present in the feces. Radioactivity in tissues accounted for the remainder of the administered dose. When expressed per gram of tissue, radioactivity was highest in liver, kidney, and forestomach. The half-life of initial elimination of radioactivity in both the urine and exhaled air was about 2 hr, indicating that ECH was rapidly absorbed and metabolized. The major metabolites in the urine were identified as N-acetyl-S-(3-chloro-2-hydroxypropyl)-L-cysteine and alpha-chlorohydrin, about 36 and 4% of the administered dose, respectively. Finding these metabolites, which have not been previously reported, is consistent ...

Background: HER2 amplification is found in 5% of RAS wild type (RASWT) metastatic colorectal cancer (mCRC). Dual HER2 blockade with trastuzumab (T) and lapatinib (L), but not treatment with either drug alone, led to remarkable inhibition of tumor growth in patient-derived tumorgrafts of HER2-amplified mCRC. CRC-specific criteria for HER2 positivity by immunohistochemistry (IHC) and in situ hybridization (ISH) were defined retrospectively in 256 CRC paraffin embedded samples (HERACLES DGX criteria). The ensuing diagnostic algorithm was utilised to screen 1299 HER2-positive tumors for therapeutic targeting in patients in the HERACLES phase 2 trial.. Methods: HERACLES was conducted at 4 Italian centres. Eligibility criteria were: RASWT exon 2, HER2 positivity, refractoriness to standard of care (including cetuximab or panitumumab), PS-ECOG , 1, and measurable. HER2 positivity was defined by IHC and ISH according to HERACLES DGX criteria. Patients (PTS) received T i.v. at 4 mg/kg loading dose ...
