Abstract
Applications of mass spectrometry (MS) are rapidly expanding and encompass molecular and cellular biology. MS aids in the analysis of in vivo global molecular alterations, identifying potential biomarkers which may improve diagnosis and treatment of various pathologies. MS has added new dimensionality to medical research. Pioneering gynecologists now study molecular mechanisms underlying female reproductive pathology with MS-based tools. Although benign gynecologic disorders including endometriosis, adenomyosis, leiomyoma, and polycystic ovarian syndrome (PCOS) carry low mortality rates, they cause significant physical, mental, and social detriments. Additionally, some benign disorders are unfortunately associated with malignancies. MS-based technology can detect malignant changes in formerly benign proteomes and metabolomes with distinct advantages of speed, sensitivity, and specificity. We present the use of MS in proteomics and metabolomics, and summarize the current understanding of the molecular pathways concerning female reproductive anatomy. Highlight discoveries of novel protein and metabolite biomarkers via MS-based technology, we underscore the clinical application of these techniques in the diagnosis and management of benign gynecological disorders. © 2015 Wiley Periodicals, Inc.

Abstract
OBJECTIVE To identify the differently expressed proteins in adenomyotic tissue compared with normal uterine muscle. DESIGN Retrospective, case-controlled study. SETTING University-based Department of Obstetrics and Gynecology and Proteomic Research Center. PATIENT(S) Ten patients who underwent transabdominal hysterectomy were included in this study. Five of them were histologically diagnosed with adenomyosis and the other five age-matched patients had cervical carcinoma in situ. INTERVENTION(S) Postoperative adenomyotic tissue and normal uterine muscle samples were collected. MAIN OUTCOME MEASURE(S) The protein extracts from paired sample tissue were separated using two-dimensional gel electrophoresis. The differently expressed protein spots were detected by gel comparison using image analysis software and identified using matrix-assisted laser desorption/ionization time of flight mass spectrometry. RESULT(S) Compared with protein profiling of normal uterine muscle, there were 12 protein spots dysregulated in adenomyotic tissue. Among them, 10 protein spots were successfully identified by mass spectrometry. CONCLUSION(S) Comparative proteomic analysis is a useful approach for the discovery of protein biomarkers for adenomyosis and understanding the pathophysiology of the disease.

Abstract
Brine shrimp Artemia were exposed under gnotobiotic conditions to a non-lethal heat shock (NLHS) from 28 to 32, 37 and 40 degrees C. Different recovery periods (2, 6, 12 and 24h) and different heat-exposure times (15, 30, 45 and 60 min) were tested. After these NLHS, Artemia was subsequently challenged with Vibrio. Challenge tests were performed in stressed and unstressed nauplii at concentrations of 10(7) cells ml(-1) of pathogenic bacteria, Vibrio campbellii and Vibrio proteolyticus. A NLHS with an optimal treatment of 37 degrees C for 30 min and a subsequent 6h recovery period resulted in a cross-protection against pathogenic Vibrio. A 100% increase in the larval survival (P < 0.05) was observed. We have also demonstrated by Western blot that a NLHS increases the expression of HSP-70 in heat-shocked (HS) treated animals. This report is the first to reveal a cross protection of a NLHS against deleterious bacterial challenges in living crustaceans. The putative role of heat shock proteins (HSPs) in this process is discussed.

Abstract
OBJECTIVE To evaluate the expression of HSP70 and pS2 and to determine whether it may be an additional prognostic variable in the prediction of recurrence and survival in rectal adenocarcinomas. METHODS The paraffin sections of 45 patients with rectal carcinoma who were treated with surgical resection were stained with HSP70 and pS2 antibodies by using the standard biotin immunoperoxidase method. Cytoplasmic staining for both antibodies was scored semiquantitatively. RESULTS Only 16 (35.6%) tumors showed a positive cytoplasmic reaction with HSP70 antibody, while pS2 expression was observed in 26 (57.8%) tumors. There was an association between HSP70 and pS2 expression (P=0.002). No correlations were found between HSP70 and pS2 expression and tumor recurrence or overall survival and other prognostic factors. However, the type of surgical resection was significantly associated with pS2 expression status (P=0.013). Significant correlations were detected between tumor recurrence and other clinicopathologic parameters, such as clinical stage, lymph node involvement, and resection type (P=0.015, P=0.015, and P=0.03, respectively). Resection type was significantly associated with clinical outcome, recurrence, and metastasis (P=0.009, P=0.03, P<0.01, respectively). In addition, there was a statistically significant relationship between clinical stage and final outcome (P=0.005). CONCLUSIONS The strong correlation between pS2 expression and incomplete surgical resection suggests that pS2 may be related to invasive tumor behavior and may also play a role in tumor recurrence, although this latter association did not reach statistical significance in this study. HSP70 expression does not appear to be related to tumor invasiveness or tumor recurrence.

Abstract
Heat shock proteins (HSP) are a large and complex family of proteins that play important roles in cellular function and survival. In previous studies, cDNA for a 45 kD human HSP (HDJ-2) was cloned and shown to be homologous to DNA-J, a bacterial HSP [F.M. Ausubel, R. Brent, R. E. Kingston, D.D. Moore, J.G. Seidman, J.A. Smith, K. Struhl, Current Protocols in Molecular Biology, John Wiley and Sons, New York, 1997; A. Chellaiah, A. Davis, T. Mohanakumar, Cloning of a unique human homologue of the Escherichia coli DNAJ heat shock protein, Biochim. Biophys. Acta 1174 (1993) 111-113]. We have also shown that the expression of HDJ-2 is highly elevated in kidney allograft biopsies of kidneys undergoing rejection [Y.G. Alevy, D. Brennan, S. Durriya, T. Howard, T. Mohanakumar, Increased expression of the HDJ-2 heat shock protein in biopsies of human rejected kidneys, Transplantation 61 (1996) 963-967]. Because of the potential importance of HDJ-2 to disease pathogenesis, we carried out studies to characterize the structure and regulation of HDJ-2. Polyclonal and monoclonal antibodies that recognize recombinant HDJ-2 were prepared and used to localize its cellular expression. HDJ-2 was found to be farnesylated but not glycosylated. This HSP was ubiquitously expressed in all of the cell types we analyzed and was localized throughout the cytoplasm and around the nuclear membrane. However, upon heat shock it migrated to the Golgi, nucleolus, and the nuclear membrane. Northern blot analysis revealed two mRNA transcripts whose synthesis was not affected by heat shock. In addition, Western blot analysis showed that expression of HDJ-2 was also not affected by heat shock. Thus, our study shows the characterization of a HSP which, because of its migration pattern upon heat shock, is an excellent candidate for a protein chaperon.

Abstract
OBJECTIVE To evaluate the pathophysiologic role of heat shock proteins and to examine the effect of danazol on these proteins in patients with endometriosis and adenomyosis. DESIGN Immunohistochemical identification of human heat shock proteins 27, 60, and 70 in endometrial glandular cells identified using monoclonal antibodies. SETTING Department of obstetrics and gynecology in a university hospital. PATIENT(S) Subjects were 119 women with documented endometriosis or adenomyosis. The subjects were divided into three groups: fertile control (n = 38), with 14 in the proliferative phase and 24 in the secretory phase; endometriosis (n = 38); and adenomyosis (n = 43), including 33 who underwent hysterectomy and 10 treated with danazol. MAIN OUTCOME MEASURE(S) Staining of glandular cells by semiquantitative immunostaining (evaluation nomogram) score. RESULT(S) Significantly increased expression of heat shock protein 27 was noted in eutopic endometrium from patients with endometriosis and adenomyosis as compared with controls, regardless of the menstrual phase. The scores for heat shock protein 27 and heat shock protein 70 in the ectopic endometrium of patients with endometriosis were low compared with those in eutopic endometrium, whereas in adenomyosis, the scores were similar to those of eutopic endometrium. After treatment with danazol, the expression of heat shock proteins returned to control levels. CONCLUSION(S) We suggest that abnormally increased expression of heat shock proteins plays a role in the pathophysiology of endometriosis and adenomyosis.

Abstract
In rat cells hyperthermia induces two hsp70 transcripts of 2.5 kb and 2.7 kb. We have cloned and determined the nucleotide sequence of a gene (named hsp70.1) encoding the 2.5 kb transcript as shown by Northern blot analysis using the 5' end and 3' end specific hybridization probes. It contains an uninterrupted open reading frame of 1926 bp, it encodes a protein of approx. 70,100 Da and the predicted amino acid sequence of its product shows 98% similarity to the mouse hsp70.1 protein. The transcription start site was localized 224 bp upstream the ATG codon by RNase protection and primer extension mapping. Upstream the transcription initiation site several potential regulatory motifs including a TATA box, two Sp1 binding sites, one inverted and one direct CCAAT box and three HSEs (heat shock elements) were found. Transfection experiments with constructs in which the CAT reporter gene was fused to fragments of the 5' end flanking sequences of the isolated gene confirmed that the promoter of the rat hsp70.1 gene is functional and heat inducible.
