Abstract
In patients with bilateral cleft lip and palate (BCLP) with protrusion and/or torsion of the premaxilla, achieving a favorable outcome with adequate facial and maxillary development remains challenging. In the present study, we report a retrospective cohort of patients with complete BCLP who were treated between 2017 and 2020 at a single center in Japan. We investigated the effects and complications of primary vomerine osteotomy (PVO) with gingivoperiosteoplasty (GPP) following pre-surgical orthodontics (PSO) for premaxillary protrusion and/or torsion. For patients with residual premaxillary protrusion and/or torsion after PSO, PVO, and GPP were performed. The distances and angles of the premaxilla were measured on dental casts before PSO, on the day of PVO, after PVO, and on the day of palatoplasty after cheiloplasty. We further assessed postoperative complications. From a total of 36 patients with complete BCLP after PSO, seven patients underwent PVO with GPP. Proper positioning of the premaxilla was achieved in all seven patients. The distance between the anterior edge of the premaxilla and the anterior edge of the lateral segment and the length of the premaxillary-lateral segment on both sides continued to decrease over time. Loosening of GPP sutures occurred in two cases, although no major complications such as necrosis of the premaxilla or fistula formation occurred. Vomerine osteotomy with GPP before primary cheiloplasty is a potential treatment option in BCLP when the premaxilla still protrudes despite PSO or because PSO cannot be applied.

Abstract
OBJECTIVE In Japan, perioperative prophylaxis of pulmonary embolism (PE) in gynecologic cancer patients with preoperative asymptomatic venous thromboembolism (VTE) has not been well established yet. The GOTIC-VTE trial was a prospective, multi-center, single-arm clinical trial to investigate the prevention of postoperative symptomatic PE onset by seamless anticoagulant therapy from the preoperative period to 4 weeks after surgery instead of using intermittent pneumatic compression. METHODS Anticoagulant therapy was started immediately after asymptomatic VTE diagnosis and stopped preoperatively according to the rules of each institution. Unfractionated heparin administration was resumed within 12 hours postoperatively, and this was followed by the switch to low-molecular-weight heparin and subsequently, edoxaban; this cycle was continued for 28 days. Primary outcome was the occurrence of symptomatic PE in 28 days postoperatively. Secondary outcomes were the incidence of VTE-related events in 28 days and 6 months postoperatively and protocol-related adverse events. RESULTS Between February 2018 and September 2020, 99 patients were enrolled; of these, 82 patients were assessed as the full analysis set, including 58 for ovarian cancer, fallopian tube, or peritoneal cancer; 21 for endometrial cancer; and 3 for cervical cancer. No symptomatic PE was observed within 28 days postoperatively; two patients had bleeding events (major bleeding and clinically relevant nonmajor bleeding) and three had grade 3 adverse events (increased alanine transaminase, aspartate aminotransferase, or gamma-glutamyl transferase). CONCLUSION The multifaceted perioperative management for gynecologic malignancies with asymptomatic VTE effectively prevented postoperative symptomatic PE. TRIAL REGISTRATION JRCT Identifier: jRCTs031180124.

Abstract
OBJECTIVES Human epididymis protein 4 (HE4), a protein secreted by ovarian tumors, has been used as an ovarian tumor marker. This study aimed to improve the usefulness of HE4 to detect malignant ovarian tumors by reviewing the cut-off values. DESIGN A retrospective study without intervention was conducted. PARTICIPANTS One hundred forty-nine healthy women (premenopausal, 126; postmenopausal, 23) and 24 patients with ovarian tumors (malignant, 12; benign, 12) participated in the study. SETTING The study used the Department of Obstetrics and Gynecology of a university hospital in Japan and the university hospital as a workplace from 2016 to 2018. METHODS The basic performance of the HE4 assay was evaluated, and the serum HE4 levels of participants were measured. Receiver operating characteristic analysis was performed using the HE4 data of the patients. RESULTS There were no significant differences in HE4 levels between the pre- and postmenopausal groups of healthy women. When the global cut-off values (premenopausal, 70 pmol/L; postmenopausal, 140 pmol/L) were adopted, the clinical sensitivity, specificity, positive predictive value, and negative predictive value were 41.7%, 91.7%, 83.3%, and 61.1%, respectively. Based on the results of the receiver operating characteristic analysis, we set the HE4 cut-off level at 60 pmol/L, regardless of the menopausal status. With the newly set cut-off value, the clinical sensitivity, specificity, positive predictive value, and negative predictive value were 66.7%, 91.7%, 88.9%, and 73.3%, respectively. That is, the clinical sensitivity of HE4 was improved without lowering specificity. LIMITATIONS The small number of subjects and the fact that the health status of the healthy women was evaluated based on questionnaires were limitations to the study. CONCLUSION A clinically useful cut-off value for HE4 as an ovarian tumor marker was established regardless of the menopausal status of the women, with improved clinical sensitivity, positive predictive value, and negative predictive value without lowering specificity. Currently, different cut-off values for HE4 in pre- and postmenopausal women are used globally. The cut-off value for CA125 was the same between pre- and postmenopausal women. Therefore, with the newly established cut-off value, HE4 can be used more conveniently in a non-specialized setting, especially when it is used in combination with CA125.

Abstract
Characteristic features of popliteal pterygium syndrome (PPS) associated with the craniofacial region include cleft palate, syngnathia, and difficulty with reconstruction. We developed a new procedure of submucosal dissection with periosteotomy to close the folded mucosa in bilateral cleft lip and palate patients with PPS. This technique could be applicable for patients with wide cleft palate.

Abstract
5502 Background: Advanced ovarian clear cell carcinoma (ACCC, stage III/IV disease) is a rare tumor characterized by chemoresistance. Bevacizumab (Bev) was approved in November 2013 in Japan and became incorporated in the treatment of advanced ovarian cancer. However, the efficacy of Bev against ACCC remain unknown. We investigated the survival outcomes for ACCC, following first-line chemotherapy with or without Bev. Methods: Patients diagnosed with ACCC at seven institutions between 2008 and 2018 were enrolled in this study. Patients underwent cytoreductive surgery and taxane-carboplatin chemotherapy (78: triweekly regimen; 30: weekly regimen; 25: dose-dense regimen; 12: others) with or without concurrent and maintenance Bev (15 mg/kg/3 weeks). We compared the progression-free survival (PFS) and overall survival (OS) before (group A, n = 102) and after (group B, n = 43) Bev approval, using Kaplan–Meier method and Cox regression model. We excluded patients with poor performance status (PS) in group A, and patients who did not receive Bev due to poor PS or thrombosis in group B. Results: There was no significant difference between two groups in terms of age (p = 0.135) and initial CA125 level (p = 0.674). Thirteen (13%) and 11 (26%) patients had stage IV disease (p = 0.058) and 2 (3%) and 7 (16%) patients were of poor PS (PS ≥2) (p = 0.004) in group A and B, respectively (p = 0.058). More patients (29/43, 67%) in group B were achieved complete resection than in A group (52/102, 51%) (p = 0.068). The median cycle of Bev in B group was 16 (interquartile range: 6-21). The median follow-up time was 36 months. The median PFS increased from 12.5months in A group to 29.7 months in B group (log-rank test: p = 0.023, Wilcoxon test: p = 0.006). The median OS increased from 34.7 months in A group to 51.4 months in B group (log-rank test: p = 0.085, Wilcoxon test: p = 0.027). Multivariate analysis revealed that Bev use (Hazard ratio (HR): 0.54, p = 0.011; HR: 0.54, p = 0.019), PS <2 (HR: 0.33, p = 0.013; HR: 0.29, p = 0.006) and completeness of resection (HR: 0.38, p < 0.001; HR: 0.37, p <0.001) were independent prognostic factors for PFS and OS. Conclusions: Incorporating Bev in first-line chemotherapy may improve PFS in patients with ACCC. [Table: see text]

Abstract
The objective of this study was to propose prognostic factors and optimal treatment strategies by analyzing the clinicopathological features and programmed death-ligand 1 (PD-L1) expression. We analyzed 31 patients diagnosed with uterine or ovarian melanoma between 1997 and 2017 in the Kansai Clinical Oncology Group/Intergroup. Twenty-four and seven patients with cervical and ovarian melanomas were included, respectively. Immune checkpoint inhibitors were used in seven patients, and the objective response rate was 40%. Notably, two patients with objective responses had a high PD-L1 expression. Ten and four patients with cervical and ovarian melanomas, respectively, had high PD-L1 immunohistochemical expressions. Multivariate analysis revealed that tumor stage was an independent prognostic factor for progression-free survival in patients with cervical melanomas. In patients with ovarian melanomas, the 1-year cumulative progression-free and overall survival rates were 0 and 29%, respectively. Kaplan-Meier analyses revealed that age <60 years was associated with poorer progression-free and overall survivals in patients with ovarian melanomas. In patients with cervical melanomas, the 1-, 3-, and 5-year cumulative overall survival rates were 53, 32, and 16%, respectively. Histological atypia was associated with a poorer progression-free survival, but there was no difference in survival between patients who underwent radical hysterectomy and those who did not. The present study is a large cohort study of uterine and ovarian melanomas, which are aggressive tumors with a significantly poor prognosis, even after standard surgery and adjuvant therapy. The use of immune checkpoint inhibitors is a promising and effective treatment option.

Abstract
STUDY QUESTION Is there a relation between specific Na+/K+ ATPase isoform expression and localization in human blastocysts and the developmental behavior of the embryo? SUMMARY ANSWER Na+/K+ ATPase α1, β1 and β3 are the main isoforms expressed in human blastocysts and no association was found between the expression level of their respective mRNAs and the rate of blastocyst expansion. WHAT IS KNOWN ALREADY In mouse embryos, Na+/K+ ATPase α1 and β1 are expressed in the basolateral membrane of trophectoderm (TE) cells and are believed to be involved in blastocoel formation (cavitation). STUDY DESIGN, SIZE, DURATION A total of 20 surplus embryos from 11 patients who underwent IVF and embryo transfer at a university hospital between 2009 and 2018 were analyzed. PARTICIPANTS/MATERIALS, SETTING, METHODS After freezing and thawing Day 5 human blastocysts, their developmental behavior was observed for 24 h using time-lapse imaging, and the expression of Na+/K+ ATPase isoforms was examined using quantitative RT-PCR (RT-qPCR). The expressed isoforms were then localized in blastocysts using fluorescent immunostaining. MAIN RESULTS AND THE ROLE OF CHANCE RT-qPCR results demonstrated the expression of Na+/K+ ATPase α1, β1 and β3 isoforms in human blastocysts. Isoforms α1 and β3 were localized to the basolateral membrane of TE cells, and β1 was localized between TE cells. A high level of β3 mRNA expression correlated with easier hatching (P = 0.0261). LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION The expression of mRNA and the localization of proteins of interest were verified, but we have not been able to perform functional analysis. WIDER IMPLICATIONS OF THE FINDINGS Of the various Na+/K+ ATPase isoforms, expression levels of the α1, β1 and β3 mRNAs were clearly higher than other isoforms in human blastocysts. Since α1 and β3 were localized to the basolateral membrane via fluorescent immunostaining, we believe that these subunits contribute to the dilation of the blastocoel. The β1 isoform is localized between TE cells and may be involved in tight junction formation, as previously reported in mouse embryos.

Abstract
We herein report a retrospective analysis of the efficacy of a combination therapy of pelvic irradiation that excluded the common iliac lymph nodes region and image-guided brachytherapy (IGBT) for non-bulky (≤4 cm) cervical cancer. Thirty-three patients with stage I-II cervical squamous cell carcinoma (≤4 cm) and without pelvic/para-aortic lymphadenopathy who were treated with definitive radiotherapy alone between February 2009 and September 2016 were included. The radiotherapy consisted of CT-based small-pelvis irradiation (whole pelvis minus common iliac lymph node area) of 20 Gy/10 fractions followed by pelvic irradiation with a midline block of 30 Gy/15 fractions and IGBT of 24 Gy/4 fractions (6 Gy/fraction for high-risk [HR] clinical target volume [CTV] D90%). In-room computed tomography (CT) imaging with applicator insertion was used for brachytherapy planning, with physical examinations and diagnostic magnetic resonance imaging (MRI) also being referred to for determination of HR CTV. Over a median follow-up of 60.5 months (range, 7-89), two patients developed distant recurrence and one developed local and distant recurrence. Two patients died from cervical cancer, one from hepatocellular carcinoma and one from non-cancerous disease. The 2/5-year local control (LC), progression-free survival (PFS) and overall survival (OS) rates were 100%/96.7%, 93.8%/90.6% and 93.9%/93.9%, respectively. No pelvic/para-aortic lymph node recurrence was observed. There were no late complications of grade 3 or higher in the small bowel, large bowel/rectum, or bladder. Our results suggest that a combination therapy of IGBT plus small-pelvis irradiation excluding common iliac lymph nodes provides reasonable clinical outcomes and can be a treatment option in non-bulky (≤4 cm) cervical squamous cell carcinoma.

Abstract
Cleft palate patients with a short palate are sometimes encountered and it is difficult to achieve effective primary palatoplasty and good speech in these cases. Our purpose was to establish an effective palatoplasty for a cleft palate patient with Randall type III short palate. Buccal musculomucosal flap on the nasal side and skin graft on the oral side were performed, along with double opposing Z-plasty. Speech improved postoperation. This procedure brought the nasopharyngeal area closer to the normal anatomical state. In terms of disadvantages, the procedure is rather complicated and depends on the engraftment rate.

Abstract
OBJECTIVE To analyze congenital lateral maxillary growth for patients with bilateral cleft lip and palate (BCLP). DESIGN A retrospective study. SETTING Kanagawa Children's Medical Center. MATERIALS Images from computed tomography (CT) of patients with BCLP and control patients that were previously used for treatment. MAIN OUTCOME MEASURES The following landmarks were used: A, the posterior most point of the piriform aperture; B, the superior most point of the acoustic meatus; C, the point at which line A-B intersects the line drawn perpendicular from line A-B to the maxillary tuberosity; and D, the apical most point of the nasal bone. The following distances were then measured using these landmarks: (1) A-B distance; (2) A-C distance; (3) A-C/A-B; (4) the angle between lines A-B and A-D (∠BAD); and (5) B-D distance. RESULT Mean A-B and A-C distances and A-C/A-B were significantly smaller in the BCLP group than in the control group (P < .01 each). Mean ∠BAD was significantly larger in the BCLP group than in the control group (P < .01). Mean B-D distance did not differ significantly between groups. CONCLUSIONS Our results indicated that the lateral maxillary segments of patients with BCLP were more posterior than those of the control group, and segment length was shorter compared to the control group on 3D-CT analysis. The lateral maxillary segments of patients with BCLP were basically suggested to originally be underdeveloped.

Abstract
Radiotherapy is an essential component of cancer therapy. Carbon ion radiotherapy (CIRT) promises to improve outcomes compared with standard of care in many cancers. Nevertheless, clinicians often observe in-field recurrence after CIRT. This indicates the presence of a subset of cancers that harbor intrinsic resistance to CIRT. Thus, the development of methods to identify and sensitize CIRT-resistant cancers is needed. To address this issue, we analyzed a unique donor-matched pair of clinical specimens: a treatment-naïve tumor, and the tumor that recurred locally after CIRT in the same patient. Exon sequencing of 409 cancer-related genes identified enrichment of somatic mutations in FGFR3 and FGFR4 in the recurrent tumor compared with the treatment-naïve tumor, indicating a pivotal role for FGFR signaling in cancer cell survival through CIRT. Inhibition of FGFR using the clinically available pan-FGFR inhibitor LY2874455 sensitized multiple cancer cell lines to carbon ions at 3 Gy (RBE: relative biological effectiveness), the daily dose prescribed to the patient. The sensitizer enhancement ratio was 1.66 ± 0.17, 1.27 ± 0.09, and 1.20 ± 0.18 in A549, H1299, and H1703 cells, respectively. Our data indicate the potential usefulness of the analytical pipeline employed in this pilot study to identify targetable mutations associated with resistance to CIRT, and of LY21874455 as a sensitizer for CIRT-resistant cancers. The results warrant validation in larger cohorts.

Abstract
The incidence of cervical intraepithelial neoplasia(CIN) among reproductive-aged women has increased in Japan. Cervical conization is commonly applied for local cervical treatment to preserve fertility. The Shimodaira-Taniguchi (S-T) conization procedure is widely used in Japan. S-T conization uses a high-frequency current and a triangular probe with a linear excision electrode to remove cervical tissue as a single informative specimen. However, alternative of an electrosurgical scalpel (ES) has the advantage of adjusting the surgical margin to the transformation zone in order to preserve the maximum amount of healthy cervical tissue with good hemostasis. The aim of this study is to retrospectively analyze data regarding surgical margin status, perioperative adverse events, cervical stenosis, and preterm birth between S-T and ES.Between January 2009 and December 2014, the medical records of 1166 patients who were diagnosed as CIN II, III, or stage 1a1 cervical cancer and who were treated with conization in 7 hospitals in Gunma Prefecture, Japan were enrolled for this retrospective study. The clinicopathological data was analyzed to statistically compare outcome between S-T and ES conization.There was no difference for age or post-operative follow-up period between ES and S-T treatments. However, positive surgical margins were significantly less frequent in patients who were treated with S-T than in those treated with ES, resulting in a reduced incidence of re-treatment for S-T in comparison with ES patients. In perioperative adverse events, S-T had more patients who were administered antibiotics. The incidence of preterm delivery and cervical stenosis did not differ significantly between the groups.We demonstrate here that S-T is an alternative procedure for cervical conization with a low risk of recurrence and acceptably low rate of adverse events such as cervical stenosis and preterm delivery. The results of this study can provide useful information for future management of patient with cervical intraepithelial neoplasia.

Abstract
A phase I study was performed to determine the recommended dose of carbon ion radiotherapy and 3D image-guided brachytherapy for histologically confirmed stage II (≥4 cm), III, or IVA cervical cancer. Dose-limiting toxicities (treatment-related toxicities occurring within three months from the start of carbon ion radiotherapy) included Grade 3 non-hematological toxicity, Grade 4 hematological toxicity, or interruption of treatment for more than two weeks due to treatment-related toxicities. Carbon ion radiotherapy consisted of whole-pelvic irradiation with 36.0 Gy (relative biological effectiveness) in 12 fractions and local boost with 19.2 Gy in four fractions for the primary site, and for positive lymph nodes. Three sessions of three-dimensional (3D) image-guided brachytherapy were administered after completion of carbon ion radiotherapy. Weekly cisplatin at a dose of 40 mg/m2 was given concurrently. At a dose level of one, a total rectosigmoid D2cc dose between 67.2 Gy and 71.3 Gy at a biological equivalent dose of 2 Gy per fraction from carbon ion radiotherapy and 3D image-guided brachytherapy was prescribed. Six patients were enrolled into this dose level. No patients developed the pre-defined dose-limiting toxicities. For late toxicities, however, one patient developed Grade 3 rectal hemorrhage requiring transfusion at 10 months after treatment. The median survival time was 50.0 months for the five surviving patients. No further dose escalation was performed, and we determined the dose of level one as the recommended rectosigmoid dose. Although our results are preliminary, the study regimen encourages further investigation (registration: UMIN000013340).

In order to clarify the association between hyperglycemia during the early period after allogeneic stem cell transplantation (allo-SCT) and adverse outcomes, we retrospectively analyzed 563 consecutive patients who underwent allo-SCT at our institute between 2008 and 2015. Patients were categorized into three groups according to mean fasting blood glucose levels on days 0-7 (normoglycemia group<110 mg/dL, n=347; mild hyperglycemia group 110-149 mg/dL, n=192 and moderate/severe hyperglycemia group≥150 mg/dL, n=24). The median follow-up was 2.7 years. Patients in the moderate/severe hyperglycemia group had significantly worse characteristics. The cumulative incidences of 2-year non-relapse mortality (NRM) and the probabilities of 2-year overall survival (OS) in the normoglycemia, mild hyperglycemia and moderate/severe hyperglycemia groups were 7.5%, 19% and 29%, respectively (P<0.01), and 69%, 53% and 33%, respectively (P<0.01). In multivariate analyses, hyperglycemia was an independent predictor of high NRM (vs normoglycemia; mild hyperglycemia, hazard ratio (HR) 2.56, 95% confidence interval (CI) 1.56-4.18; moderate/severe hyperglycemia, HR 4.46, 95% CI 1.92-10.3) and poor OS (vs normoglycemia; mild hyperglycemia, HR 1.54, 95% CI 1.14-2.07; moderate/severe hyperglycemia, HR 1.61, 95% CI 0.89-2.91). In conclusion, hyperglycemia on days 0-7 after allo-SCT was associated with inferior outcomes.

Abstract
Retinoic acid (RA) is a metabolite of vitamin A and has important roles in development, differentiation, and reproduction. Activin has been shown to regulate the RA pathway and affect granulosa cell (GC) proliferation, suggesting that RA is important for early follicle development. However, little is known about the effects of RA on GC functions, particularly steroidogenesis, during the early follicle stage. The aim of this study was to investigate the effects of all-trans-RA (atRA) on progesterone production in immature rat GCs cultured without gonadotropin. Our results demonstrated that atRA enhanced progesterone production by upregulating the levels of steroidogenic acute regulatory protein (StAR) and cytochrome P450scc (Cyp11a1) mRNAs, but not 3β-hydroxysteroid dehydrogenase mRNA in immature rat GCs. Additionally, analysis of the mechanisms through which atRA upregulated StAR and Cyp11a1 mRNAs revealed that atRA enhanced intracellular cAMP accumulation and phosphorylation of cAMP response-element binding protein (CREB). In addition, H-89, an inhibitor of protein kinase A (PKA), abolished the stimulatory effects of atRA, indicating that atRA enhanced progesterone synthesis through cAMP/PKA signaling. In conclusion, our data demonstrated that atRA has a crucial role in progesterone synthesis in rat GCs during the early follicle stage. atRA upregulated StAR and Cyp11a1 and enhanced progesterone production. atRA enhanced intracellular cAMP accumulation and phosphorylation of CREB. Inhibition of PKA abolished the stimulatory effects of atRA. atRA mediated progesterone synthesis in rat GCs during the early follicle stage.

Abstract
Leptomeningeal metastasis (LM) of uterine cervical cancer is extremely rare. A 54-year-old woman with uterine cervical cancer treated with surgery and radiotherapy developed LM manifesting as ptosis 17 years later. Although rare, LM should be considered in patients with a history of uterine cervical cancer presenting with cranial nerve symptoms.

Abstract
Several inflammatory cytokines regulate ovarian function. TNF-α is produced in granulosa cells under physiological conditions and has a reciprocal action on follicle development. In contrast, in pelvic inflammatory diseases, TNF-α is excessively produced in the pelvic cavity and has an adverse effect on reproductive functions. The objective of this study was to elucidate the mechanism of action of TNF-α on the expression of LH receptor (LHR) in immature rat granulosa cells. TNF-α suppressed FSH-induced LHR mRNA and protein expression and was not associated with cAMP accumulation. By using a luciferase assay, the construct containing base pairs -1389 to -1 of the rat Lhcgr promoter revealed that TNF-α decreased FSH-induced promoter activity. In response to TNF-α, nuclear factor (NF)-κB p65 was translocated to the nucleus, and the suppressive effect of TNF-α on LHR mRNA expression was abrogated by an NF-κB inhibitor. In a chromatin immunoprecipitation assay, TNF-α induced the association of NF-κB p65 with the rat Lhcgr transcriptional promoter region. NF-κB p65 and histone deacetylase (HDAC) interact to mediate expression of several genes at a transcriptional level. HDAC activity is thought to induce tight connections within local chromatin structures and repress gene transcription. Furthermore, the TNF-α-induced suppression of LHR mRNA expression was blocked by an HDAC inhibitor. Taken together, these results suggest that the interaction of NF-κB p65 with HDAC in the promoter region of rat Lhcgr might be responsible for TNF-α action on the regulation of LHR.

Abstract
AIM Amino acid transporters are essential for the growth, progression and the pathogenesis of various cancers. However, it remains obscure about the clinicopathological significance of L-type amino acid transporter 1 (LAT1) and system ASC amino acid transporter 2 (ASCT2) for patients with human ovarian tumors. The aim of this study is to elucidate the prognostic role of these amino acid transporters in ovarian tumor. METHODS One-hundred forty-two patients with surgically resected ovarian tumors were analyzed by immunohistochemistry. Expression of LAT1, ASCT2, CD98, Ki-67 and microvessel density (MVD) determined by CD34 were evaluated using specimens of the resected tumors. RESULTS LAT1 and ASCT2 were positively expressed in 39% and 53%, respectively, of ovarian tumors (n=142) and 50% and 57%, respectively, of epidermal ovarian cancers (n=107). A positive LAT1 expression was closely correlated with the expression for ASCT2 and CD98, and cell proliferation (Ki-67) in ovarian cancer. By multivariate analysis, LAT1 was clarified as a significant independent marker for predicting a poor overall survival (OS). The expression of LAT1 could clearly discriminate between epidermal ovarian cancer and borderline malignancy. The expression level of LAT1 within ovarian cancer cells varied among serous adenocarcinoma, endometrioid adenocarcinoma, clear cell adenocarcinoma and mucinous adenocarcinoma and we found LAT1 expression was higher in clear cell adenocarcinoma than other histological types. CONCLUSIONS LAT1 is highly expressed in various ovarian tumors and a positive LAT1 expression can serve as a significant independent factor for predicting a poor OS in patients with epidermal ovarian cancer.

Abstract
The mucosal graft and flaps method (MG method) is a palatoplasty technique that was developed for the purpose of improving maxillary growth in patients with cleft palate. In the MG method, full-thickness buccal mucosa is grafted onto the raw surface created by pushback palatoplasty. The method is unlikely to result in severe scarring and has a favorable effect on maxillary growth. In addition, it is unlikely to result in oronasal fistula and provides good speech results. Overall, postive long-term treatment results have been obtained. Although the MG method is technically difficult and requires a lengthy surgery, the technique is considered to be effective for palate closure in terms of speech and maxillary growth.

Abstract
AIMS Squamous cell carcinoma (SCC) is the most common form of malignant transformation in mature cystic teratoma (MCT) of the ovary. Some investigators have suggested the possibility of origin from columnar epithelium. The aim of this study was to analyse such tumours immunohistochemically to elucidate their histogenesis. METHODS AND RESULTS The expression of cytokeratin (CK) 10 and CK18 was examined in 21 samples of SCC arising in MCT. The expression of CK10 and CK18 was also assessed in SCCs arising in different organs (skin, vulva, lung and uterine cervix) for the purpose of comparison. SCC in MCT expressed CK10 in 7/21 cases [33.3%, 95% confidence interval (CI) 0.12-0.53] and CK18 in 14/21 cases (66.7%, 95% CI 0.46-0.87). SCC in MCT expressed CK10 less frequently, but CK18 more frequently, as is the case in SCCs of the uterine cervix (CK10, 20%; CK18, 70%) and the lung (CK10, 5%; CK18, 90%), both of which are derived from columnar epithelium by squamous metaplasia. CONCLUSIONS SCC in MCT may be derived from metaplastic squamous epithelium.

Abstract
5013 Background: NAC may represent an alternative to conventional RH for locally advanced cervical cancer. We compared NAC followed by RH with RH for bulky stage I/II cervical cancer. Methods: Patients (pts) with stage IB2, IIA (> 4 cm), or IIB squamous cell carcinoma of the uterine cervix were randomly assigned to receive either BOMP (bleomycin 7mg day 1–5, vincristine 0.7mg/m2 day 5, mitomycin 7mg/m2 day 5 and cisplatin 14 mg/m2 day 1–5,) q21 days, 2 to 4 cycles followed by radical hysterectomy (NAC arm) or undergo RH (RH arm). Pts with positive surgical margins, metastatic nodes, infiltration to parametrium, and/or deep myometrial invasion received postoperative irradiation. Eligibility included preserved organ function, aged 20–70, and Performance Status 0 or 1. Primary endpoint was overall survival (OS) to be compared by log-rank test. Assuming 100 eligible pts in each arm, the study had 80% power to detect a 15% increase in 5-year survival at 0.05 one-sided alpha. Results: 134 pts (67 NAC, 67 RH) were randomized between 12/01 and 08/05. The first planned interim analysis was performed in July 2005 using data from 108 pts registered as of 11/04. Data and Safety Monitoring Committee recommended to terminate the study because overall survival in NAC arm was inferior to that in RH arm (HR 2.11, multiplicity adjusted 99% CI 0.34 to 13.2) and the predictive probability of significant superiority using Spiegelhalter’s method of NAC arm was extremely low (6.4%). No increase of operability and no decrease of surgery-related morbidity were observed in NAC arm. Response Rate of NAC was 61% (33 of 54) using RECIST criteria. One-year progression-free survival and overall survival, updated as of 05/05, were 69.9% and 91.8% (95% CI 84.1–99.6) in NAC arm and 78.6% and 95.4% (95% CI 89.1–100) in RH arm respectively. Conclusions: Neoadjuvant chemotherapy with BOMP regimen followed by radical hysterectomy did not demonstrate clinical benefit, and conventional radical hysterectomy still remains to be a standard treatment option for bulky stage I/II cervical cancer.

Abstract
15020 Background: Retrospective analyses revealed that survival of ovarian cancer patients treated with NAC followed by IDS was comparable with those treated by standard treatment starting with primary debulking surgery. The purpose is to assess the safety and efficacy of the NAC setting treatment and also to know whether we can accurately diagnose the cancer by imaging studies, cytologic findings and tumor markers without diagnostic laparoscopy (DLS). Methods: The study was performed as a multi-institutional non-randomized phase II trial. Eligibility included stage III/IV müllerian carcinoma (MC) such as ovarian, tubal and peritoneal carcinomas diagnosed by imaging studies (CT and/or MRI), cytology of ascites, pleural effusions or fluids obtained by tumor centesis, CA125 >200 U/ml and CEA<20 ng/ml. After study enrollment, DLS is performed to confirm tumor origin, histology and stage. Four cycles of combination of paclitaxel (175 mg/m2, 3h) and carboplatin (AUC 6) are administered as NAC, followed by IDS and additional 4 cycles of chemotherapy. Primary endpoint is proportion of clinical complete remission (% cCR) with CA 125<20 U/ml among all stage III/IV MC confirmed by DLS (expected % cCR of 40% and threshold % cCR of 20%). Major secondary endpoint is positive predictive value (PPV) of clinical diagnoses concerning origin, histology and stage (expected PPV>90%, then DLS will be omitted in the next phase III study). The planned sample size was 56 eligibles, which gives 10% or lower Bayesian posterior probability that PPV is < 90% in case of three false positives. Results: Fifty six patients were enrolled between Jan/2003 and Feb/2004. All patients had accurate pre-DLS diagnosis concerning origin and histology. In 53 (PPV 94.6%) of 56 patients, tumor stage was accurately diagnosed. Twenty nine (62%) of 47 patients who underwent IDS had complete resection without residual tumors. Nineteen (%cCR 36%) among 53 patients with stage III/IV MC achieved cCR at completion of planned treatment. Conclusions: NAC starting without DLS followed by IDS for advanced MC is a promising treatment to be compared with the current standard treatment in a phase III study. [Table: see text]

Abstract
OBJECTIVE Early cervical adenocarcinoma (ECA) with a tumour depth of <3 mm has a good prognosis. To clarify the cytological features of ECAs with depth <3 mm, these were compared with those of ECA with 3-5 mm and invasive adenocarcinoma (IA) invading the cervical wall with more than 5 mm in depth. METHODS The cervical cytological features of ECAs with depth <3 mm (14 cases) were compared with those of ECA with 3-5 mm (four cases) and IA (13 cases). Cytologically, the presence or absence of tumour diathesis, number of atypical cells, crowded cell groups, groups with glandular structures, feathering, groups with palisading borders, rosettes, clusters, cell shape and size, nuclear shape and size, nucleolar shape and size, chromatin distribution, border and character of cytoplasm, and single cell pattern were evaluated. RESULTS A tumour diathesis was seen in five of 14 ECA <3 mm in depth (36%), all four ECA with 3-5 mm (100%) and 11 of 13 IA with more than 5 mm (85%). Single cells, macronucleoli and coarsely granular chromatin pattern were less frequent in ECA of <3 mm than that in ECA with 3-5 mm and IA. The number of atypical cells and glandular structures in ECA was significantly less than that in IA. Cell crowding, feathering, palisading and rosettes were common in both ECA and IA. CONCLUSION The characteristic cytological features of ECA with depth <3 mm, having a good prognosis, were clean background, fewer single cells and macronucleoli, and less frequent coarsely granular chromatin pattern compared with those in ECA with 3-5 mm and IA. The number of atypical cells and glandular structures in ECA was significantly less than that in IA. Familiarity with the cytological features of ECA and its mimics is essential.

Abstract
OBJECTIVE The aim of this study was to determine whether or not we could distinguish uterine papillary serous carcinoma (UPSC) from other types of endometrial cancer by cytology. METHODS We examined the cytological findings of the endometrium from five cases with UPSC and compared them with 10 cases with endometrioid adenocarcinoma, grade 1 (G1). A morphometric analysis was performed. Cytological samples from the cervix and ascites of the patients with UPSC were also reviewed. RESULTS All five patients had FIGO stage III and IV tumours. Three patients died of the disease and two are still alive with disease. The tumour cells of UPSC tended to be shed in papillary clusters with a tumour diathesis. Psammoma bodies were seen only in UPSC. The frequency of irregular-shaped nuclei, membrane thickness and eccentric nuclei in UPSC was higher than in G1. The chromatin pattern was coarsely granular, and both anisonucleosis and bare nuclei were prominent in UPSC. Cytomorphometrically, the maximum diameter of the nuclei in UPSC was significantly greater than that in G1. The nucleoli were also more often seen in UPSC than in G1. The findings of the nuclei and nucleoli in the cervical and peritoneal fluid cytology closely resembled those in endometrial smears. The features of the cervical smears and peritoneal fluid cytology were different from those of endometrial cytology regarding clear background and small clusters of cells. CONCLUSION As the endometrial cytology findings accurately suggested the histological diagnosis of UPSC, the diagnosis of UPSC was confirmed in this study by endometrial cytology. The cytological diagnosis of UPSC should be based on the findings of tumour diathesis, psammoma bodies and papillary clusters composed of tumour cells with enlarged nuclei and numerous nucleoli.

Abstract
We investigated the energetic costs of quadrupedal and bipedal walking in two Japanese macaques. The subjects were engaged in traditional bipedal performance for years, and are extremely adept bipeds. The experiment was conducted in an airtight chamber with a gas analyzer. The subjects walked quadrupedally and bipedally at fixed velocities (<5 km/hr) on a treadmill in the chamber for 2.5-6 min. We estimated energy consumption from carbon dioxide (CO2) production. While walking bipedally, energetic expenditure increased by 30% relative to quadrupedalism in one subject, and by 20% in another younger subject. Energetic costs increased linearly with velocity in quadrupedalism and bipedalism, with bipedal/quadrupedal ratios remaining almost constant. Our experiments were relatively short in duration, and thus the observed locomotor costs may include presteady-state high values. However, there was no difference in experimental duration between bipedal and quadrupedal trials. Thus, the issue of steady state cannot cancel the difference in energetic costs. Furthermore, we observed that switching of locomotor mode (quadrupedalism to bipedalism) during a session resulted in a significant increase of CO2 production. Taylor and Rowntree ([1973] Science 179:186-187) noted that the energetic costs for bipedal and quadrupedal walking were the same in chimpanzees and capuchin monkeys. Although the reason for this inconsistency is not clear, species-specific differences should be considered regarding bipedal locomotor energetics among nonhuman primates. Extra costs for bipedalism may not be great in these macaques. Indeed, it is known that suspensory locomotion in Ateles consumes 1.3-1.4 times as much energy relative to quadrupedal progression. This excess ratio surpasses the bipedal/quadrupedal energetic ratios in these macaques.

Abstract
Mutants of the human (h) lutropin receptor (LHR) were analyzed using a combination of biochemical and imaging approaches to define motifs that participate in the postendocytotic sorting of this G protein-coupled receptor (GPCR). We show that a substantial portion of the human chorionic gonadotropin internalized by the hLHR sorts to a recycling pathway, and the internalized hLHR accumulates in endosomes because of the C-terminal cysteine (Cys(699)) and an upstream Leu(683) present in the hLHR. The removal or simultaneous mutation of these two residues reroutes the internalized human chorionic gonadotropin to a degradation pathway and the internalized hLHR to lysosomes. We also show that grafting the 17 C-terminal residues of the hLHR into the C-terminal tail of two GPCRs that are routed to a lysosomal/degradation pathway (the rat LHR or the murine delta opioid receptor) reroutes them to an endosomal/recycling pathway. This is due to the Leu(683) and Cys(699) combination and another recycling motif (Gly(687)Thr(688)) that was previously identified in the hLHR. The importance of both motifs can be readily ascertained in the context of a murine delta opioid receptor/hLHR chimera. The importance of the Gly(687)Thr(688) motif is revealed mostly in the context of a rat LHR/hLHR chimera. These studies define a novel, noncontiguous, transferable motif that participates in the sorting of internalized GPCRs.

Abstract
In this study, we attempted to assess the effects of insulin-like growth factor-1 (IGF-1) and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on follicle-stimulating hormone (FSH)-induced luteinizing hormone (LH) receptor expression in rat granulosa cells to understand the effects of these factors on normal reproductive function. Treatment with FSH, as expected, produced a substantial increase in LH receptor mRNA expression level, and cotreatment with an increasing concentration of IGF-1 resulted in a dose-dependent increase in FSH-induced LH receptor mRNA expression level. On the other hand, the cotreatment with FSH and TCDD (10 pM) resulted in a significant decrease in LH receptor mRNA expression level after 24 h. The decay curves for the LH receptor mRNA transcript showed a significant increase in half-life after the addition of IGF-1 and a significant decrease after the addition of TCDD. These data suggest a possible role for changes in LH receptor mRNA stability in the IGF-1- and TCDD-induced regulation of the LH receptor in rat granulosa cells. The rates of LH receptor mRNA gene transcription, assessed by nuclear run-on transcription assay, did not increase after the addition of IGF-1, but decreased after the addition of TCDD. The data for IGF-1 indicate that the interface between circulating hormones and paracrine/autocrine systems could provide an important mechanism for amplifying the effects of gonadotropin hormones at the local level. In addition, the endocrine-disrupting effects of TCDD are, at least in part, caused by the direct action on the LH receptor expression on granulosa cells.

Abstract
The placental trophoblast is considered to act as a barrier between mother and fetus, mediating the exchange of various materials across the placenta. ATP-binding cassette (ABC) transporters such as P-glycoprotein (P-gp) and multidrug-resistance protein (MRP) are expressed in the placenta and function as efflux transport systems for xenobiotics. In the present study, we aimed to determine the localization of MRP1 in the human placenta in comparison with that of P-gp. Western blotting analysis with human placental membrane vesicles indicated that P-gp and MRP1 are localized on the brush-border membranes and basal membranes, respectively. Immunohistochemical analysis with human normal full-term placenta showed that anti-P-gp monoclonal antibody F4 stained the brush-border side of the trophoblast cells, whereas anti-MRP1 monoclonal antibody MRPr1 stained the basal side. These results confirm that P-gp and MRP1 are located on the brush-border membranes and basal membranes, respectively, of human full-term placental trophoblast. MRP1 was also detected on the abluminal side of blood vessels in the villi. Accordingly, MRP1 may play a role distinct from that of P-gp, which is considered to restrict the influx of xenobiotics into the fetus.

Abstract
Although the fates of the internalized hormone-receptor complexes formed by the lutropin/choriogonadotropin and the TSH receptors have been examined in some detail, much less is known about the fate of the internalized FSH-FSH receptor (FSHR) complex. Using biochemical and imaging approaches we show here that the majority of the internalized FSH-FSHR complex accumulates in endosomes and subsequently recycles back to the cell surface where the bound, intact hormone dissociates back into the medium. Only small amounts of FSH and the FSHR are routed to a lysosomal degradation pathway, and the extent of FSH-induced down-regulation of the cell surface and total FSHR is minimal. This pathway was detected in heterologous (human kidney 293T) cells transfected with the rat (r) or human (h) FSHR as well as in a mouse Sertoli cell line (MSC-1) or a mouse granulosa cell line (KK-1) transfected with the rFSHR.Additional experiments using a series of C-terminal deletions of the rFSHR and the hFSHR showed that the recycling of the internalized FSH-FSHR complex and the extent of hFSH-induced down-regulation is dictated by a short stretch of amino acids present at the extreme C-terminal end of the receptor.We conclude that most of the internalized FSH-FSHR complex is recycled back to the cell surface, that this recycling pathway is highly dependent on amino acid residues present near the C terminus of the FSHR, and that it is an important determinant of the extent of down-regulation of the FSHR.

Abstract
The pathways involved in activation of the ERK1/2 cascade in Leydig cells were examined in MA-10 cells expressing the recombinant human LH receptor (hLHR) and in primary cultures of rat Leydig cell precursors. In MA-10 cells expressing the recombinant hLHR, human choriogonadotropin-induced activation of ERK1/2 is effectively inhibited by overexpression of a cAMP phosphodiesterase (a manipulation that blunts the human choriogonadotropin-induced cAMP response), by addition of H89 (a selective inhibitor of protein kinase A), or by overexpression of the heat-stable protein kinase A inhibitor, but not by overexpression of an inactive mutant of this inhibitor. Stimulation of hLHR did not activate Rap1, but activated Ras in an H89-sensitive fashion. Addition of H89 to MA-10 cells that had been cotransfected with a guanosine triphosphatase-deficient mutant of Ras almost completely inhibited the hLHR-mediated activation of ERK1/2. We also show that 8-bromo-cAMP activates Ras and ERK1/2 in MA-10 cells and in primary cultures of rat Leydig cells precursors in an H89-sensitive fashion, whereas a cAMP analog 8-(4-chloro-phenylthio)-2'-O-methyl-cAMP (8CPT-2Me-cAMP) that is selective for cAMP-dependent guanine nucleotide exchange factor has no effect. Collectively, our results show that the hLHR-induced phosphorylation of ERK1/2 in Leydig cells is mediated by a protein kinase A-dependent activation of Ras.

Abstract
The present study was undertaken to identify the mechanisms underlying the effect of transforming growth factor (TGF) beta on FSH receptor (FSH-R) in rat granulosa cells. Compared to the control, the treatment of granulosa cells with TGFbeta (10 ng/ml) increased FSH-R mRNA transcripts (5.5 and 2.4 kilobases) in a time-dependent manner, with a maximum increase of approximately 2-fold at 48 h. We then investigated whether the effect of TGFbeta on FSH-R mRNA levels was the result of increased transcription and/or altered mRNA stability. To determine whether the FSH-R 5'-flanking region plays a role in directing FSH-R mRNA expression, the proximal area of the FSH-R 5'-flanking regions were inserted into an expression vector, pGL-Basic, which contains luciferase as the receptor gene, and the resulting plasmids were transiently transfected into rat granulosa cells. The FSH (30 ng/ml) significantly enhanced the activity of 1862 base pairs of the FSH-R 5'-flanking region, but treatment with TGFbeta did not significantly influence the activity induced by FSH. On the other hand, the decay curves for FSH-R mRNA transcript in primary granulosa cells showed a significant increase in half-life after the addition of TGFbeta. Transforming growth factor beta stimulates the expression of follistatin mRNA accumulation in a dose- and time-dependent manner. Treatment with activin produced a substantial increase in FSH-R mRNA level. Concurrent treatment with follistatin neutralized this activin effect on FSH-R mRNA, as reported, although concurrent treatment with follistatin did not affect TGFbeta-induced FSH-R mRNA. Therefore, the profile of the TGFbeta effect on FSH-R mRNA granulosa cells may be caused by the increased stability of FSH-R mRNA and insensitivity to the follistatin.

Abstract
By using a yeast two-hybrid screen we identified GIPC (GAIP-interacting protein C terminus), a protein with a type I PDZ domain as a novel human lutropin receptor (hLHR) binding partner. Pull-down and immunoprecipitation assays confirmed this interaction and showed that it is dependent on the PDZ domain of GIPC and the C-terminal tetrapeptide of the hLHR. To characterize the functional consequences of the GIPC-hLHR interaction, we used a small interfering RNA against GIPC to generate a clonal cell line that is deficient in GIPC. Studies with this cell line reveal that GIPC is partially responsible for the recycling of the hormone that is internalized by the hLHR and also for maintaining a relatively constant level of hLHR at the cell surface during hormone internalization.

Abstract
PURPOSE The aim of the present study was to establish the accurate cutoff points of post-treatment serum beta-hCG values in identifying chemotherapeutic refractory cases among patients with low-risk persistent trophoblastic disease (PTD) treated with 8-day methotrexate-folinic acid as the primary therapy. MATERIALS AND METHODS The values of serum beta-hCG measured before initiating treatment and weekly thereafter in 26 patients with low-risk PTD undergoing 8-day methotrexate-folinic acid treatment were analyzed. Thereafter, we determined the weekly cutoff points to identify the patient refractory for treatment by means of receiver-operating characteristic (ROC) plots analysis. RESULTS The values of cutoff points in the pretreatment, the post-treatment 1st, 2nd, 3rd, and 4th week were 18.6, 15.0, 5.4, 3.4, and 2.0 ng/ml, respectively, and the value of accuracy during these weeks was appropriate (> 80%). When using the cutoff points of one and two weeks after initiating treatment, the accuracy in identifying chemotherapeutic refractory patients was 87.5% and 88.0%, respectively, with the highest values exceeding 85%. The sensitivity and specificity at one week were 92.9 and 80.0%, respectively. Similarly, the sensitivity and specificity at two weeks were 93.3 and 80.0%, respectively. CONCLUSION These results suggest that the cutoff points of one and two weeks after initiating treatment are useful in identifying chemotherapeutic refractory patients among low-risk PTD patients, receiving 8-day methotrexate-folinic acid treatment.

Abstract
Using a Leydig tumor cell line (MA-10) transiently transfected with the human lutropin receptor (hLHR) and mutants thereof, we examined the identity of the G proteins activated by the agonist-engaged hLHR-wild type (wt) and by three of its naturally occurring constitutively active mutants. Two of the mutants examined, L457R in transmembrane helix 3 and D578Y in transmembrane helix 6, are germ-line mutations found in boys with Leydig cell hyperplasia and precocious puberty. The third, D578H, is a somatic mutation found in Leydig cell tumors in boys with precocious puberty. We show that the hLHR-wt and the three mutants activate the G(s), G(i/o), and G(q/11), but not the G(12/13), families of G proteins. The activation of these G proteins by the hLHR-wt occurs only when engaged by agonist, but their activation by the L457R, D578Y, and D578H mutants occurs independently of agonist stimulation. We conclude that the G proteins activated by constitutively active mutants of the hLHR associated with Leydig cell hyperplasia or tumors are identical and are the same as those activated by the agonist-engaged hLHR-wt. If there was preferential activation of some G protein families by the somatic D578H mutation found in Leydig cell tumors as opposed to the germ line mutations found in Leydig cell hyperplasia, then one could envision mechanisms by which the D578H mutant would be oncogenic. The data presented here suggest that such mechanisms do not need to be considered.

Abstract
RCAS1, which acts as a ligand for a putative receptor on immune cells such as peripheral lymphocytes and natural killer cells, is strongly expressed in human cancers. RCAS1 can induce these cells to undergo apoptotic cell death, which suggests that RCAS1 expression may prohibit the stromal reaction occurring in a tumour. To clarify the clinical significance of RCAS1 expression in uterine endometrial cancer, we analysed the association between RCAS1 expression and clinicopathologic variables by statistical methods. With the use of immunohistochemical techniques, we performed a retrospective study of RCAS1 expression in resected tumour tissue from 147 patients with uterine endometrial cancer. We evaluated the statistical correlation between RCAS1 expression and clinicopathologic variables. RCAS1 was expressed in 106 of 147 patients with uterine endometrial cancer; 30 of these 147 patients showed RCAS1 overexpression. Overexpression of RCAS1 was significantly correlated with age at surgery, stage, extent of myometrial invasion, and positive peritoneal cytologic results. Multivariate analysis revealed that RCAS1 expression and metastasis were clinically significant prognostic factors for the overall survival. These findings indicated that analysis for RCAS1 expression can provide crucial information about the clinical behaviour of uterine endometrial cancer, which may be valuable for the management of patients with this disease.

Abstract
Ovarian granulosa cells undergo a complex differentiation process during the growth and maturation of ovarian follicle. This process includes the acquisition of cell surface LH receptor, which mediates the granulosa cell's ability to respond to circulating LH. The results of the actions of LH on the mature granulosa cell include steroidogenesis, luteinization, and ovulation. As such, induction of the LH receptor in granulosa cells is a critical step in reproductive physiology. In the present study, we attempted to assess the effects of IGF-1 and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on FSH-induced LH receptor expression in rat granulosa cells to understand the actions of these factors on normal reproductive function. Treatment with FSH, as expected, produced a substantial increase in LH receptor mRNA level, and concurrent treatment with increasing concentrations of IGF-1 brought about dose-dependent increases in FSH-induced LH receptor mRNA. On the other hand, the concurrent treatment of TCDD (10 pM) resulted in a significant decrease in LH receptor after 24 h. The decay curves for LH receptor mRNA transcript showed a significant increase in the half-life after the addition of IGF-1 and a significant decrease after addition of TCDD. These data suggests a possible role for changes in LH receptor mRNA stability in the IGF-1 and TCDD induced regulation of LH receptor in rat granulosa cells. The rates of LH receptor mRNA gene transcription, assessed by nuclear run-on transcription assay, were not increased by the addition of IGF-1, but decreased by the addition of TCDD. The data of IGF-1 present that the interface between circulating hormones and paracrine/autocrine systems could provide an important mechanism to amplify the effects of gonadotropin hormones at the local level. In addition, the endocrine-disrupting effects of TCDD are, at least in part, caused by direct action on the expression of LH receptor expression in granulosa cells.

Abstract
The present study was undertaken in order to identify the mechanism underlying the effect of transforming growth factor-beta (TGFbeta) on LH receptor (LH-R) expression in rat granulosa cells. Treatment with FSH produced a substantial increase in LH-R mRNA level, and concurrent treatment with increasing concentrations of TGFbeta brought about dose-dependent increases in FSH-induced LH receptor mRNA. TGFbeta, either alone or in combination with FSH, did not affect intracellular cAMP levels. We then investigated whether the effect of TGFbeta and FSH on LH-R mRNA levels results in increased transcription and/or altered mRNA stability. To determine whether the LH receptor 5'-flanking region plays a role in directing LH receptor mRNA expression, the proximal area of the LH receptor 5'-flanking regions were inserted into an expression vector, pGL-Basic, which contains luciferase as the receptor gene, and the resulting plasmids were transiently transfected into rat granulosa cells. FSH (30 ng/ml) significantly enhanced the activity of 1389 base pairs of the LH receptor 5'-flanking region, but treatment with TGFbeta did not significantly influence the activity induced by FSH. On the other hand, the decay curves for LH-R mRNA transcript in primary granulosa cells showed a significant increase in half-life after the addition of TGFbeta.
