This study was designed to evaluate the significance of cyclooxygenase (COX)-2 and epidermal growth factor receptor (EGFR) expression in a series of cervical adenocarcinoma (AC), cervical adenosquamous carcinoma (ASC), and cervical squamous cell carcinoma (SCC). One hundred thirty cases of cervical carcinoma (30 ASC, 50 AC, and 50 SCC) were analyzed for(More)
Solid tumor cells are known to be highly glycolytic and, to prevent apoptosis by cellular acidosis, cells increase proton efflux through pH regulators, such as monocarboxylate transporters (MCTs). However, the role of these membrane proteins in solid tumor development and survival is not fully understood. We aimed to evaluate the expression of the MCT(More)
Due to the highly glycolytic metabolism of solid tumours, there is an increased acid production, however, cells are able to maintain physiological pH through plasma membrane efflux of the accumulating protons. Acid efflux through MCTs (monocarboxylate transporters) constitutes one of the most important mechanisms involved in tumour intracellular pH(More)
Adenosquamous carcinoma of the uterine cervix is an infrequent but aggressive subtype of cervical cancer. A better understanding of its biological behaviour is warranted to define more accurate prognosis and therapeutic targets. Currently, the blockage of receptor tyrosine kinase (RTKs) activity is an efficient therapeutic strategy for many different(More)
Cervical cancer is one of the most common cancers in women worldwide, being high-risk group the HPV infected, the leading etiological factor. The raf kinase inhibitory protein (RKIP) has been associated with tumor progression and metastasis in several human neoplasms, however its role on cervical cancer is unclear. In the present study, 259 uterine cervix(More)
We prospectively analyzed a homogeneous group of 65 patients with perforated duodenal ulcer whose medical condition (no perioperative shock, no associated disease, underwent laparotomy within 12 hours after perforation, and an APACHE II score below 11) would have little effect on the outcome of surgery to study the influence of the surgical procedure(More)
BACKGROUND Sparganosis is not a common disease, and its rarity makes it difficult to distinguish from others. Close examination of fine needle aspiration biopsy (FNAB) samples, however, can aid in histologic examination of the lesion. CASE A 64-year-old female, born and raised in a rural area in the state of Goiás, Brazil, presented with a relatively(More)
OBJECTIVES Uterine adenosquamous carcinoma (ASC) is an uncommon, yet, one of the most aggressive cervical cancer subtype. The successful treatment of some tumors, such as gastrointestinal stromal tumors (GISTs), by anti-KIT inhibitors fosters the study of this receptor tyrosine kinase in other malignancies. In the present study, we intended to molecularly(More)
Deregulation of cellular energetic metabolism was recently pointed out as a hallmark of cancer cells. This deregulation involves a metabolic reprogramming that leads to a high production of lactate. Lactate efflux, besides contributing for the glycolytic flux, also acts in the extracellular matrix, contributing for cancer malignancy, by, among other(More)
