Abstract
Preeclampsia (PE) remains the major cause for maternal and foetal mortality and morbidity all over the world. Preeclampsia is associated with maternal, placental aggravated inflammatory response and generalized endothelial damage. AnnexinA1 (AnxA1) is glucocorticoid regulated protein regulates a wide range of cellular and molecular steps of the inflammatory response and is implicated in resolution of inflammation. Galectin-3 (Gal-3), β-galcotoside-binding lectin participates in many functions, both intra- and extracellularly. Recently it has been shown that galectin-3 modulates the inflammation. Role of AnxA1 and Galectin-3 is poorly studied in context with human reproductive disease like Preeclampsia. Therefore, the present study examined the expression of AnxA1 and Gal-3 which are involved in modulation of inflammation and their association in the placental bed of pregnancy with and without PE. The study group consisted of placental bed biopsy tissues obtained from pregnancies with PE (n = 30) and without (n = 30) PE. The expression of AnxA1 and Gal-3 in the placental bed tissues was evaluated quantitatively using Immunohisto-chemistry (IHC), western blot and mRNA expression analysis by quantitative RT-PCR. Our IHC, western blot and RT PCR analyses showed the increase in the expression of AnxA1 and Gal-3 in PE group compared with the normotensive control group (P < 0.001). The increased expression of AnxA1 and Gal-3 in placental bed may be associated with a systemic inflammatory response in PE, suggesting role of AnxA1 and Gal-3 in PE pathogenesis.

Abstract
OBJECTIVES Preeclampsia (PE) remains the major cause for maternal and foetal mortality and morbidity. Invasion of endovascular trophoblast and remodelling of spiral artery are crucial actions of normal placental development. Non-fulfilment of these processes plays a leading role in the development of preeclampsia. Vascular endothelial growth factor (VEGF) is produced by extravillous trophoblastic tissue and decidual cell population is a well-known angiogenic growth which plays a fundamental role in placental pathogenesis of PE. Annexin A2 (ANXA2) is a profibrinolytic protein receptor required for plasminolysis, which is an important step in the formation of new blood vessel along with VEGF. Role of ANXA2 is poorly studied in context with human reproductive disease like preeclampsia. The purpose of the present study is to examine the expression and association of VEGF and ANXA2 in the term placentas of pregnancies with and without PE. METHODS The study group comprised of placental tissues procured from gestations with PE (n=30) and without (n=20) PE. The expression of VEGF and ANXA2 in the placental villous tissue was evaluated quantitatively by means of IHC, western blotting and reverse transcriptase-polymerase chain reaction (RT-PCR). RESULTS Our IHC, western blotting and RT-PCR analysis illustrated the significant decrease in the expression of VEGF and ANXA2 in PE group compared with the normotensive control group (p<0.005). We observed statistically significant positive correlation among the expression of ANXA2 and VEGF in placentas of normotensive control group (p<0.0001). CONCLUSIONS The diminished expression of VEGF and ANXA2 in placenta may be associated with the defective angiogenesis and which may possibly play a vital role in PE pathogenesis.

Abstract
Background The expression in the glomerular mesangial cells, papillary, and collecting duct cells demonstrated annexin A1 (AnxA1)'s role in specific renal functions. With varying concentrations of calcium (Ca2+), it is considered to regulate cellular processes such as cell proliferation, apoptosis, and clearance of apoptotic cells by forming ceramides, a key lipid mediator of apoptosis. It also participates in tumorigenesis based on its location. On account of these features, we investigated the expression of this apoptosis-associated protein in fetal kidneys at different gestational periods, mature kidneys and in kidney cancer tissues in order to localize and possibly characterize its role during nephrogenesis and renal tumors. Methods AnxA1 expression was evaluated by an immunohistochemistry technique in "paraffin-embedded" renal tissue sections from autopsied fetuses at different gestational ages, in mature kidneys and renal cancer tissues. Results The current study data demonstrated that AnxA1 is expressed in the mesangial cells and podocytes of maturing glomeruli in the developing renal cortex of fetal kidneys at 14 to 19 weeks of gestation. The expression in the mesangial cells declined in later weeks of gestation and persisted into adulthood. AnxA1 expression increased with the progression of clear cell renal cell carcinoma (CCRCC) and also in other cancer types indicating a potential role of the protein in tumorigenesis. Conclusions We presume that AnxA1 in the podocytes and mesangial cells play important roles in various signaling pathways in the functioning of the glomerulus. These results and concepts provide a framework to further dissect its biological properties and thereby develop diagnostic, prognostic, and therapeutic strategies targeting the molecule in various renal pathologies.

Abstract
Aberrant activation of β‐catenin has been implicated in a variety of human diseases, including cancer. In spite of significant progress, the regulation of active Wnt/β‐catenin‐signaling pathways is still poorly understood. In this study, we show that F‐box protein 16 (FBXO16) is a putative tumor suppressor. It is a component of the SCF (SKP1‐Cullin1‐F‐box protein) complex, which targets the nuclear β‐catenin protein to facilitate proteasomal degradation through the 26S proteasome. FBXO16 interacts physically with the C‐terminal domain of β‐catenin and promotes its lysine 48‐linked polyubiquitination. In addition, it inhibits epithelial‐to‐mesenchymal transition (EMT) by attenuating the level of β‐catenin. Therefore, depletion of FBXO16 leads to increased levels of β‐catenin, which then promotes cell invasion, tumor growth, and EMT of cancer cells. Furthermore, FBXO16 and β‐catenin share an inverse correlation of cellular expression in clinical breast cancer patient samples. In summary, we propose that FBXO16 functions as a putative tumor suppressor by forming an SCFFBXO16 complex that targets nuclear β‐catenin in a unique manner for ubiquitination and subsequent proteasomal degradation to prevent malignancy. This work suggests a novel therapeutic strategy against human cancers related to aberrant β‐catenin activation. © 2019 The Authors.

Abstract
The creation of a cancer cell could be due to reactivation of repressed gene in the process of normal embryonic development. The differences in embryonic origins and functions of various components of nephron may contribute to the diversity of morphological patterns, molecular and immunohistochemical phenotypes of common renal neoplasms. Renal cell carcinomas (RCCs) are the most common amongst the genitourinary cancers. Annexin A2 (AnxA2) is a multifunctional calcium-regulated phospholipids-binding protein found in a subset of renal neoplasms. Since the tumor cells usually recapitulate embryonic cells, we studied the ontogeny of AnxA2 in developing renal tissues and compared it with those of normal adult RCCs, to better understand their role in renal development and tumorigenesis. AnxA2 immunoexpression was evaluated by immunohistochemistry from various autopsied fetuses, mature kidney and renal cancer tissue specimens. The study showed moderate membranous AnxA2 immunoexpression in the ureteric buds and collecting tubules of fetal kidneys (in all gestational ages) and in the collecting ducts of adult normal renal tissues. It is not often expressed in the proximal convoluted tubules of normal adult kidney; however, younger fetal kidneys show moderate AnxA2 immunoexpression in the proximal convoluted tubules (thought to be the origin of RCC) and the reappearance of strong membranous AnxA2 immunoexpression in the clear cell carcinoma is suggesting a deregulation of the gene during tumorigenesis. The understanding of the AnxA2 molecular immunoexpression pattern during development, its specific function and deregulated immunoexpression in different renal carcinoma types indicates the decisive role of AnxA2 in the cancer progression.

Abstract
Intravascular papillary endothelial hyperplasia (IPEH) is a rare cause of orbital mass which can affect healthy individuals of any age/sex/race/region. It usually requires a histopathological examination, characterized by the appearance of papillary proliferation of vascular endothelial cells within the lumen of the blood vessel, for the final diagnosis. One should be aware that this is a highly vascular lesion which can cause excessive intraoperative bleeding and incomplete removal can lead to recurrences. IPEH of the orbit/eyelid has been reported in few parts of the world as isolated case reports but none from India so far.

Abstract
Background AnnexinA2 (AnxA2) membrane deposition has a critical role in HB-EGF shedding as well as IL-6 secretion in breast cancer cells. This autocrine cycle has a major role in cancer cell proliferation, migration and metastasis. The objective of the study is to demonstrate annexinA2-mediated autocrine regulation via HB-EGF and IL-6 in Her-2 negative breast cancer progression. Methods Secretory annexinA2, HB-EGF and IL-6 were analysed in the peripheral blood sample of Her-2 negative ( n = 20) and positive breast cancer patients ( n = 16). Simultaneously, tissue expression was analysed by immunohistochemistry. The membrane deposition of these secretory ligands and their autocrine regulation was demonstrated using triple-negative breast cancer cell line model. Results Annexina2 and HB-EGF expression are inversely correlated with Her-2, whereas IL-6 expression is seen in both Her-2 negative and positive breast cancer cells. RNA interference studies and upregulation of annexinA2 proved that annexinA2 is the upstream of this autocrine pathway. Abundant soluble serum annexinA2 is secreted in Her-2 negative breast cancer (359.28 ± 63.73 ng/mL) compared with normal (286.10 ± 70.04 ng/mL, P < 0.01) and Her-2 positive cases (217.75 ± 60.59 ng/mL, P < 0.0001). In Her-2 negative cases, the HB-EGF concentrations (179.16 ± 118.81 pg/mL) were highly significant compared with normal (14.92 ± 17.33 pg/mL, P < 0.001). IL-6 concentrations were increased significantly in both the breast cancer phenotypes as compared with normal ( P < 0.001). Conclusion The specific expression pattern of annexinA2 and HB-EGF in triple-negative breast cancer tissues, increased secretion compared with normal cells, and their major role in the regulation of EGFR downstream signalling makes these molecules as a potential tissue and serum biomarker and an excellent therapeutic target in Her-2 negative breast cancer.

Abstract
Overexpression and activation of tyrosine kinase receptors like EGFR and Src regulate the progression and metastasis of Her-2 negative breast cancer. Recently we have reported the role of cell membrane interaction of phospholipid-binding protein annexin A2 (AnxA2) and EGFR in regulating cellular signaling in the activation of angiogenesis, matrix degradation, invasion, and cancer metastasis. Beta-galactoside-specific animal lectin galectin-3 is an apoptosis inhibitor, and cell surface-associated extracellular galectin-3 also has a role in cell migration, cancer progression, and metastasis. Similar expression pattern and membrane co-localization of these two proteins made us to hypothesize in the current study that galectin-3 and AnxA2 interaction is critical for Her-2 negative breast cancer progression. By various experimental analyses, we confirm that glycosylated AnxA2 at the membrane surface interacts with galectin-3. N-linked glycosylation inhibitor tunicamycin treatment convincingly blocked AnxA2 membrane translocation and its association with galectin-3. To analyze whether this interaction has any functional relevance, we tried to dissociate this interaction with purified plant lectin from chickpea (Cicer arietinum agglutinin). This highly specific 30 kDa plant lectin could dissociate AnxA2 from endogenous lectin galectin-3 interaction at the cell surface. This dissociation could down-regulate Bcl-2 family proteins, cell proliferation, and migration simultaneously triggering cell apoptosis. Targeting this interaction of membrane surface glycoprotein and its animal lectin in Her-2 negative breast cancer may be of therapeutic value.

Abstract
Adrenal myelolipoma is characterized by presence within the adrenal gland of mature adipose tissue and active bone marrow elements. Owing to their non functional nature most cases are incidental, either at autopsy or through computer tomography scan. Occasionally the lesions attain a large size to become clinically apparent. We present a case of a 58-year-old female with mass per abdomen. Preoperative computer tomography scan of abdomen, hormonal and urine analysis showed features of non functional adrenal myelolipoma. Gross specimen consists of unilateral ovoid mass, external surface having capsule with adherent fat and areas of congestion. Microscopic examination showed well encapsulated tumour tissue composed of mature adipose tissue with major blood forming elements like myeloid, erythroid and megakaryocytic series. The diagnosis was confirmed by histopathological examination of right sided adrenalectomy specimen.

Abstract
Graham Little-Piccardi-Lassueur syndrome is a type of lichen planopilaris (follicular lichen planus) characterized by the triad of patchy cicatricial alopecia of the scalp, noncicatricial alopecia of the axilla and groin, and a follicular spinous papule on the body, scalp, or both. It is four times more common in females in the age group of 30-70 years. Only a few cases have been reported in literature wherein the disease has affected males. Herein we report a young male who presented with features of Graham Little-Piccardi-Lassueur syndrome.

Abstract
A 40-year-old male who was diagnosed to be having ileocaecal tuberculosis by colonoscopy elsewhere was put on antitubercular treatment. Despite therapy over three months patient had recurrent bouts of lower abdominal pain and was admitted repeatedly with features of subacute intestinal obstruction. CT- abdomen revealed concentric large bowel thickening at multiple sites with features of stenosing lesions. Patient underwent an exploratory laparotomy and subtotal colectomy was done for the diseased large bowel. Post operative histopathological examination revealed it to be Behcet's disease. We report a rare case of intestinal Behcet's disease requiring subtotal colectomy.

Abstract
Luteinized thecomas are one of the sex cord stromal tumors of the ovary rarely undergoing ossification. We report a case of a 66-year-old post-menopausal female with the chief complaint of uterine bleeding of 7 months duration. Endometrial curettage performed showed features of endometrial adenocarcinoma. Follow-up total abdominal hysterectomy revealed bilateral luteinized thecomas of the ovary, one of which had undergone massive ossification converting the ovary into a bone. True bone formation in ovarian tumors is rare. This case is the second in the literature of osseous metaplasia in an ovarian luteinized thecoma, with the association of endometrial adenocarcinoma suggesting its functional status.

Abstract
Mammary hamartomas are uncommon benign lesions rarely associated with malignancy. We report a case of a 25-year-old female patient presenting with a lump in the left breast. Fine needle aspiration cytology showed features of invasive ductal carcinoma along with normal benign glands that were mistaken for normal breast tissue. However, the mastectomy specimen revealed the malignant mass within a larger hamartomatous mass. Mammary hamartomas are benign lesions but, on exceedingly rare occasions, they may be involved by incidental, coexisting carcinoma, as illustrated in this case report.
