OBJECTIVES: Human Epididymal Secretory Protein 4 was firstly described as an epididymis-specific protein but more recently it has been demonstrated to be a putative serum tumor marker for different malignancies, especially ovarian epithelial cancers. The aim of this study is to investigate the association between tissue Human Epididymal Secretory Protein 4 expression and the clinicopathological features of uterine cervical tumors. MATERIAL AND METHODS: This retrospective study was designed to evaluate the differences of tissue expressions of Human Epididymal Secretory Protein 4 protein in a spectrum of cervical neoplasms...

Adenocarcinoma of cervix constitutes about 10-15% cases of carcinoma cervix. Clear cell variant is even a rarer variant of adenocarcinoma. It rarely occurs in the paediatric age group and a known risk factor is in utero exposure to diethylstilbestrol (DES). We report here a case of primary cervical tumour in a 1-year-old girl, which was initially suspected to be an embryonal rhabdomyosarcoma botryoides. Histopathology with immunohistochemical analysis revealed clear cell adenocarcinoma. There was no maternal history of DES intake during pregnancy...

Our previous in vitro studies demonstrated that oxygen pretreatment significantly protects human embryonic renal tubular cell against acute cisplatin- (CP-) induced cytotoxicity. The present study was designed to investigate whether this protective effect is associated with decreasing therapeutic effects of cisplatin on malignant cells. For this purpose, cultured human embryonic kidney epithelial-like (AD293), cervical carcinoma epithelial-like (Hela), and ovarian adenocarcinoma epithelial-like (OVCAR-3) cells were subjected to either 2-hour pretreatment with oxygen (≥90%) or normal air and then to a previously determined 50% lethal dose of cisplatin for 24 hours...

Galaxamide, an extract from Galaxaura filamentosa, is a cyclic pentapeptide containing five l-leucines. Due to the particular cyclic structure and the excellent anticancer activity, synthesis of Galaxamide and its analogs and their subsequent bio-applications have attracted great attention. In the present work, we synthesized six Galaxamide analogs by replacing one of the l-leucines with phenylalanine and varying the d-amino acid position. The anticancer effect of the synthesized Galaxamide analogs was tested against four in vitro human cancer cell lines, human hepatocellular cells (HepG₂), human breast cancer cell (MCF-7), human breast adenocarcinoma cells (MDA-MB-435) and a human cervical carcinoma cell line (Hela)...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

Clear cell adenocarcinoma of the cervix (CCAC) is a rare type of gynecological cancer. The risk factors and pathogenesis have yet to be clearly determined. This is a case report of a 19-year-old woman, who was never exposed to DES from her mother, who had gone for an examination for vaginal bleeding. A polypoid mass measured at 3 cm presenting in her cervix was discovered. Histological diagnosis following cervical biopsy proved the tumor to be a clear cell carcinoma. The patient was then referred to our hospital...

The fast growing use of nanoparticles (NPs) in biotechnology and biomedicine raises concerns about human health and the environment. When introduced in physiological milieus, NPs adsorb biomolecules (especially proteins) forming the so-called protein corona (PC). As it is the PC that mostly interacts with biological systems, it represents a major element of the NPs' biological identity with impact on nanotoxicology, nanosafety and targeted delivery of nanomedicines. To date, NP-protein interactions have been largely investigated in vitro, but this condition is far from mimicking the dynamic nature of physiological environments...

In daily practice, signet ring cell morphology immediately brings to the mind the possibility of an adenocarcinoma at first glance. The signet ring cell appearance has been described and is well-known in a wide variety of some other neoplasms as well. Surprisingly however, neoplastic cells having the same morphology can unexpectedly be encountered in not previously well-documented tumors. Here, we present an 85-year-old man diagnosed with primary pulmonary squamous cell carcinoma and a large signet ring cell population...

Objective Expectant follow-up for biopsy-proven cervical intraepithelial neoplasia (CIN) 1 is the current recommendation for the management of this lesion. Nevertheless, the performance of the biopsy guided by colposcopy might not be optimal. Therefore, this study aimed to calculate the rate of underdiagnoses of more severe lesions in women with CIN 1 diagnosis and to evaluate whether age, lesion extent and biopsy site are factors associated with diagnostic failure. Methods Eighty women with a diagnosis of CIN 1 obtained by colposcopy-guided biopsy were selected for this study...

Persistent HPV infection alone is not sufficient for cervical cancer development, which requires additional molecular alterations for tumor progression and metastasis ultimately leading to a lethal disease. In this study, we performed a comprehensive analysis of HER family receptor alterations in cervical adenocarcinoma. We detected overexpression of HER protein, mainly HER2, which was an independent prognostic marker for these patients. By using in vitro and in vivo approaches, we provided evidence that HER inhibitors, allitinib and lapatinib, were effective in reducing cervical cancer aggressiveness...

The anti-cancerous activity of 6-gingerol extracted from Tongling White Ginger was investigated. 6-Gingerol inhibited the growth of HeLa cells with IC50 (96.32 μM) and IC80 (133.01 μM) and led to morphological changes, induced the cell cycle arrest in G0/G1-phase and ultimately resulted into apoptosis. Among cell cycle-related genes and proteins, the expression of cyclin (A, D1, E1) reduced, while of CDK-1, p21 and p27 showed slight decrease, except cyclin B1 and E1 (protein). Western blotting reported the induction of apoptosis with an increased Bax/Bcl-2 ratio, release of cytochrome c, cleavage of caspase-3, -8, -9 and PRPP in treated cells...

Human papillomavirus (HPV) infection is closely associated with cervical cancer. This study analyzed HPV genotype prevalence in 75 cases of formalin-fixed paraffin embedded (FFPE) tissue samples from patients diagnosed with cervical cancer. Genotype prevalence was assessed using Reverse Blot Assay (REBA) and quantitative polymerase chain reaction (qPCR), which target the HPV L1 and HPV E6/E7 genes, respectively. HPV DNA chip tests were also performed using liquid based preparation (LBP) cytological samples from the same patients who provided the FFPE histological samples...

Caveolin-1 (Cav-1), a major structural protein of caveolae, is an integral membrane protein which plays an important role in the progression of carcinoma. However, whether Cav-1 acts as a tumor promoter or a tumor suppressor still remains controversial. For example, the tumor-promoting function of Cav-1 has been found in renal cancer, prostate cancer, tongue squamous cell carcinoma (SCC), lung SCC and bladder SCC. In contrast, Cav-1 also plays an inhibitory role in esophagus adenocarcinoma, lung adenocarcinoma and cutaneous SCC...

Chromatin remodeling alters gene expression in carcinoma tissue. Although cervical cancer is the fourth most common cancer in women worldwide, a systematic study about the prognostic value of specific changes in the chromatin structure, such as histone acetylation or histone methylation, is missing. In this study, the expression of histone H3 acetyl K9, which is known to denote active regions at enhancers and promoters, and histone H3 tri methyl K4, which preferentially identifies active gene promoters, were examined as both show high metastatic potential...

PURPOSE: A hallmark of cancer is metabolic reprogramming, which is exploited by cancer cells to ensure rapid growth and survival. Pyruvate kinase M2 (PKM2) catalyzes the final step in glycolysis, a key step in tumor metabolism and growth. Recently, we reported the radiosynthesis of the first positron emission tomography tracer for visualizing PKM2 in vivo-i.e., [(11)C]DASA-23. Due to the highly promising imaging results obtained with [(11)C]DASA-23 in rodent model glioblastoma, we set out to generate an F-18-labeled version of this tracer, with the end goal of clinical translation in mind...
