Objective: To determine whether interstitial collagenase (matrix metalloproteinase-1), known to play a pivotal role in the initiation of menstruation, contributes to the pathogenesis of endometriosis. Design: Serial sections of peritoneal red and black endometriotic lesions, ovarian endometriotic cysts, and rectovaginal adenomyotic nodules were analyzed by in situ hybridization for the expression of matrix metalloproteinase-1 by silver staining for the integrity of the fibrillar extracellular matrix and by immunolabeling for the abundance of sex steroid receptors. Setting: Academic hospital and research laboratory. Patient(s): Premenopausal women undergoing laparoscopy for endometriosis. Intervention(s): Biopsy of endometriotic lesions, combined with endometrium whenever possible. Main Outcome Measure(s): Expression of matrix metalloproteinase-1 messenger RNA (mRNA). Result(s): Matrix metalloproteinase-1 mRNA was expressed focally in red peritoneal and ovarian endometriosis irrespective of the phase of the menstrual cycle but was not detectable in black peritoneal and rectovaginal lesions. Foci of matrix metalloproteinase-1 expression closely correlated with matrix breakdown and with the absence of P receptors in adjacent epithelial cells. Conclusion(s): Correlation of matrix metalloproteinase-1 expression with activity of endometriotic tissue suggests its involvement in tissue remodeling and bleeding, and possibly in the secondary shedding and reimplantation of endometriotic lesions.

Hysteroscopic resection of an intrauterine septum may benefit patients suffering from infertility or recurrent pregnancy loss. A partial or complete uterine septum can be easily resected using a Nd-YAG laser. If present, the vaginal septum may also be removed during the same procedure. The reproductive outcome of women treated by operative hysteroscopy for an intrauterine septum is reviewed. To avoid pregnancy in a non-communicating rudimentary horn, the removal of the horn and the homolateral tube may be performed by either bipolar coagulation or a CO2 laser. [less ▲]

The expression of members of the IGF system in a mesothelioma from a patient suffering from hypoglycemia, in term placenta and HT29 colon adenocarcinoma cells were compared. Very high levels of IGF-II mRNA and protein were detected in the mesothelioma. Moreover, half of the IGF-II protein took the high-molecular-weight form. We also analyzed the parental imprinting status and the promoter usage of the IGF-II gene. Our results showed loss of imprinting (LOI) in the mesothelioma while the imprinting was maintained in HT29 cells, expressing moderate levels of the transcript. Promoter P4 was active in the three tissues we analyzed, whereas IGF-II mRNA transcription from promoter P3 was only detected in the mesothelioma and the placenta, expressing comparably high levels of the transcript. IGF-II gene structure was identical in the analyzed tissues and cells. The type-I receptor mRNA expression was very low in the tumor. IGFBP-2, -4 and -5 mRNAs were detected in the mesothelioma, while IGFBP-2, -3 and -5 transcripts were detected in the placenta. IGFBP-1 and -6 transcripts were not detected. [less ▲]

The production of beta-lactamase in Streptomyces cacaoi, which contains two beta-lactamase-encoding genes, blaL and blaU, is inducible by beta-lactam compounds. The two genes have been cloned independently in S. lividans TK24, a beta-lactamase-negative species. The blaU clone did not respond to the presence of beta-lactams, whereas the blaL clone appeared to be inducible in S. lividans. The latter clone contains two open reading frames, blaA and blaB, located just upstream of but transcribed divergently from blaL, which were shown to be required for the production as well as the induction of BlaL. The deduced BlaA protein belongs to the LysR family of transcription regulators. In order to examine the role of BlaA in regulation, we here report on over-expression of a GST-BlaA fusion protein in Escherichia coli and its use for antibody preparation. The GST-BlaA fusion protein was partially purified and bandshift assays showed that it bound the 197-bp blaL-blaA intergenic region. The BlaA DNA binding-site was further restricted to a 30-bp sequence containing a T-N11-A motif, a characteristic of LysR-type promoters. Another T-N11-A motif upstream of the blaU gene was also shown to bind BlaA. The affinities of these two T-N11-A motifs in BlaA binding were comparable. A plasmid bearing the blaU structural gene and the blaA-blaB regulatory region was constructed and shown to confer on an S. lividans host the capacity to produce inducible beta-lactamase. It can thus be concluded that the S. cacaoi blaL and blaU genes are controlled by the same regulatory system. [less ▲]

Purpose: To analyze the clinical characteristics, prognosis, and treatment outcome of pelvic cryptorchid seminoma (PCS), and to determine whether whole abdominal-pelvic irradiation for Stage I disease is necessary. Methods and Materials: From 1958 to 1991,60 patients with PCS were treated at the Cancer Hospital of Chinese Academy of Medical Sciences, Beijing. They presented with a lower abdominal mass and showed a predominance for the right side. A high proportion of patients with PCS [ 26 of 60 (43% )] had metastatic disease, compared to 20% of those with scrotal seminoma, and there was a tendency toward a higher frequency of pelvic nodal metastases. There were 34 Stage I, 6 Stage IIA, 11 Stage IIB, 5 Stage III, and 4 Stage IV patients. Of these 60 patients, 56 underwent laparotomy with or without cryptorchiectomy (37 radical orchiectomy, 7 partial orchiectomy, and 12 biopsy of the primary or cervical node), and 4 cervical node biopsy only. All patients were further treated with radiotherapy, chemotherapy, or a combination of both. Patients with Stage I and II disease received radiotherapy, whereas patients with Stage III and IV were treated with chemotherapy. Results: The overall and disease-free survivals at 5 and 10 years were 92% and 87%, and 88% and 84%, respectively. The 5- and lo-year survivals were 100% for Stage I, 94% and 87% for Stage II, and 56% and 42% for Stage III/IV, respectively @ < 0.05). Volume of irradiation, i.e., whole abdominal-pelvic radiotherapy ( 10 patients), versus hockey-stick encompassing paraaortic, ipsilateral iliac nodes and the primary tumor or tumor bed (17) did not influence outcome in Stage I patients. Five patients relapsed within 2-12 years after treatment, and four of these patients were successfully salvaged. Four patients developed a second malignant tumor and died. Conclusion: Stage I and II PCS can he adequately controlled by radiotherapy regardless of the surgical procedure. Whole abdominal-pelvic irradiation for Stage I and IIA disease is not required, and fields can be limited to the paraaortic, ipsilateral iliac nodes and primary tumor or tumor bed. We recommend platinum-based chemotherapy for Stage IIB-IV PCS. 0 1997 Elsevier Science Inc. [less ▲]
