The wide use of assisted reproductive technologies has contributed to the increased risk of ectopic and subsequently heterotopic pregnancy (HP) rate. Cervical ectopic pregnancy is a very rare and life-threatening form of ectopic pregnancy that can also present as HP. We are describing here a case of 34-year-old woman who presented with bleeding heterotopic cervical pregnancy (HCP). The concomitant viable cervical and intrauterine pregnancies were diagnosed at 8 weeks of gestation. Selective fetal reduction was done for cervical pregnancy following which uterine artery embolization was done as a life-saving measure, and subsequently, injection methotrexate was also given...

Loss of the tumor suppressor NDRG2 has been implicated in the development of oral squamous cell carcinoma (OSCC), acting by modulating PI3K/AKT-mediated dephosphorylation of PTEN at S380/S382/T383 (STT). Here we show that the majority of OSCC tumors with lymph node metastasis, a major prognostic factor, exhibit high levels of phosphorylated AKT-S473 and PTEN-STT and low levels of NDRG2 expression. In Ndrg2-deficient mice, which develop a wide range of tumors, we developed a model of OSCC by treatment with the tobacco surrogate 4-nitroquinoline-1-oxide (4-NQO)...

BACKGROUND: The pregnancy outcome of the unicornuate uterus is associated with an increased risk of miscarriage, cervical incompetence, and a number of obstetric complications. However, at present, there is no accepted treatment method for women with unicornuate uterus, other than expectant measures. The aim of this study was to evaluate the reproductive outcome of transcervical uterine incision (TCUI) in patients with unicornuate uterus. METHODS: Thirty-three patients with unicornuate uterus presented to our tertiary center for infertility or miscarriage...

Ectopic parathyroid is found in 16% of patients with hyperparathyroidism. 2% of ectopic parathyroid adenomas are not accessible to standard cervical excision. In such cases, video-assisted thoracoscopic resection is the recommended definitive treatment. We present a case of mediastinal parathyroid adenoma localized preoperatively by injecting methylene blue within a branch of the internal mammary artery that is supplying the adenoma. Intra-arterial methylene blue injection facilitated visualization and resection of the adenoma...

Increasing evidence has shown that miRNAs are implicated in carcinogenesis and can function as oncogenes or tumor suppressor genes in human cancers. In this study, we confirmed that miR-214 is frequently down-regulated in cervical cancer compared with normal cervical tissues. Ectopic expression of miR-214 suppressed proliferation, migration and invasion of HeLa and C33A cervical cancer cells. Bioinformatics analysis revealed that ADP ribosylation factor like 2 (ARL2) was a potential target of miR-214 and was remarkably up-regulated in cervical cancer...

Cool-associated tyrosine phosphorylated protein-1 (Cat-1) is a signaling scaffold, as well as an ADP-ribosylation factor-GTPase-activating protein (ARF-GAP). Although best known for its role in cell migration, we recently showed that the ability of Cat-1 to bind paxillin, a major constituent of focal complexes, was also essential for the anchorage-independent growth of HeLa cervical carcinoma cells. Here, we set out to learn more about the underlying mechanism by which Cat-paxillin interactions mediate this effect...

INTRODUCTION: Substernal goiters are characterized by the protrusion of at least 50% of the thyroid mass below the level of the thoracic inlet. Still their definition is controversial. CASE PRESENTATION: The case refers to a 44year old male who presented to our department due to swelling and a feeling of 'heaviness' of his left upper extremity for the past 6 months. CT scan revealed a massive substernal goiter extending to the great vessels. Intraoperatively, a median sternotomy was performed due to the size of the gland and the close adhesion of the isthmus and lower left thyroid lobe to the brachiocephalic vein...

: The cytidine deaminase APOBEC3B (A3B) underlies the genetic heterogeneity of several human cancers including cervical cancer, which is caused by human papillomavirus (HPV) infection. We previously identified a region within the A3B promoter that is activated by the viral protein HPV16 E6 in human keratinocytes. Here, we discovered three sites recognized by the TEAD family of transcription factors within this region of the A3B promoter. Reporter assays in HEK293 cells showed that exogenously expressed TEAD4 induced A3B promoter activation through binding to these sites...

Progression from human papillomavirus-induced premalignant cervical intraepithelial neoplasia (CIN) to cervical cancer (CC) is driven by genetic and epigenetic events. Our microarray-based expression study has previously shown that inter-α-trypsin-inhibitor heavy chain 5 (ITIH5) mRNA levels in CCs were significantly lower than in high-grade precursor lesions (CIN3s). Therefore, we aimed to analyze in depth ITIH5 expression during cervical carcinogenesis in biopsy material and cell culture. Moreover, functional analyses were performed by ectopic expression of ITIH5 in different cell lines...

BACKGROUND: Nasopharyngeal carcinoma (NPC) is a malignant epithelial carcinoma of the head and neck with strong ability of invasion and metastasis. Our previous study indicated that miR-324-3p, as a tumor-suppressive factor, could regulate radioresistance of NPC cells by targeting WNT2B. The purpose of this study is to investigate the role of miR-324-3p on migration and invasion in NPC cells. METHODS: Quantitative real time PCR was applied to measure the expression level of miR-324-3p and WNT2B mRNA in both cells and tissues, and the expression level of WNT2B protein was determined by western blotting...

Tazarotene-induced gene 1 (TIG1) is a retinoic acid-inducible protein that is considered a putative tumor suppressor. The expression of TIG1 is decreased in malignant prostate carcinoma or poorly differentiated colorectal adenocarcinoma, but TIG1 is present in benign or well-differentiated tumors. Ectopic TIG1 expression led to suppression of growth in cancer cells. However, the function of TIG1 in cell differentiation is still unknown. Using a yeast two-hybrid system, we found that transmembrane protein 192 (TMEM192) interacted with TIG1...

Ectopic/aberrant cervical thymic tissue is a rare cause of neck mass and usually detected incidentally. Aberrant thymic tissue can occur anywhere in the course of thymic descent from the angle of the mandible to the superior mediastinum. We report a case of aberrant cervical thymus demonstrated by ultrasound.

OBJECTIVES: Cervical pregnancy (CP) is a rare type of ectopic pregnancy. Methotrexate (MTX) appears to be the first-line therapy for clinically stable women; however, there is still no consensus on the most appropriate treatment for this abnormal pregnancy. The aim of the present study was to investigate the efficacy of a single local MTX injection under transvaginal ultrasound guidance for the initial treatment of CP and to assess the post-treatment fertility. METHODS: We retrospectively reviewed 15 CP patients treated with local MTX injection under transvaginal ultrasonography...

BACKGROUND: Cervical ectopic pregnancy can lead to catastrophic hemorrhage, and may be managed conservatively with intra-amniotic methotrexate (MTX), systemic MTX, or both; surgical evacuation with or without balloon tamponade; and uterine artery embolization. However, some patients require hysterectomy, which has traditionally been performed abdominally. CASE: A 39-year-old parous woman was diagnosed with cervical ectopic pregnancy at an estimated 7 1/7 weeks of gestation...

Lysine-specific demethylase 1 (LSD1), which specifically demethylates histone H3 lysine 4 (H3K4) and lysine 9 (H3K9), is dysregulated in several cancers. We found that ectopic expression of LSD1 in cervical cancer cells promoted invasion and metastasis in vitro and in vivo, reduced the expression of the epithelial marker E-cadherin, and induced the expression of the mesenchymal marker, Vimentin. By contrast, LSD1 knockdown had the opposite effect and attenuated the HPV16 E7-induced epithelial-mesenchymal transition (EMT)...

Ectopic glucose-6-phosphate dehydrogenase (G6PD) expression may contribute to tumorigenesis in cervical cancer associated with high-risk human papillomavirus (HR-HPV 16 and 18) infections. Here, we demonstrate that microRNA-1 (miR-1) in association with AGO proteins targets G6PD in HR-HPV-infected human cervical cancer cells. miR-1 inhibited expression of a reporter construct containing a putative G6PD 3'-UTR seed region and suppressed endogenous G6PD expression. Down-regulation of miR-1 increased G6PD expression in cervical cancer cells...

It has been reported that miRNAs is deregulated in diverse human cancers, involving human cervical cancer. However, the clinical significances and potential mechanisms of miR-142 in the development and progression of cervical cancer were not elucidated completely till now. In this study, we found that the expression of miR- 142 was obviously down-regulated in human cervical cancer tissues and a panel of cell lines. According to statistics, the expression of miR-142 was negatively related to advanced FIGO stage and lymphatic metastasis (p < 0...
