zn (ii) is an important regulator of caspase-3, as well as an antioxidant, microtubule stabilizer, growth cofactor, and anti-inflammatory agent. over the past 30 years, many researchers have demonstrated the important role of zn (ii) in a variety of physiological processes, including growth and development, maintenance and priming of the immune system, and in tissue repair and regeneration. in ...

Human esophageal cancer‑related gene 4 (ECRG4) is a potential tumor suppressor gene isolated from human esophageal epithelial cells. Studies have shown that ECRG4 effectively inhibits the proliferation of tumor cells and induces apoptosis. However, the role of ECRG4 in laryngeal cancer has not yet been clearly defined. In this study, a human laryngeal cancer cell line stably overexpressing ECRG...

Introduction: Laryngectomy in patients with laryngeal cancer can lead to the reduction of nutritional parameters. Supportive treatments and supplementary nutritional supports are recommended in all patients undergoing laryngectomy, even with acceptable preoperative nutritional indices.The aim of this study was to evaluate postoperative changes in nutritional parameters in patients with larynge...

The purpose of this study was to assess and explain the relationship between molecular changes occurring in squamous cell laryngeal carcinoma. Furthermore, we were revealed the role of FHIT gene response in the development and progression of squamous cell laryngeal carcinoma, and genes based exons 7,8 and 9 in tumour stage and histopathologic grade. In this study was used 50 blood samples for c...

Laryngeal cancer is one of the most commonly occurring malignant cancers of the head and neck region. In the present study, we investigated the roles of miR-221 in laryngeal squamous cell carcinoma cell line, Hep-2. We examined the function and mechanism of miR-221 in Hep-2 cells using techniques of cell biology and molecular pathology, such as western blotting, quantitative PCR, immunohistoche...

Background The Brazilian National Cancer Institute (INCA) estimated last year almost forty thousand new cancer cases of laryngeal carcinoma, melanoma, tracheal, bronchial and lung cancer. It is known that multidrug resistance and unspecific toxicity are the major challenges for commercial anticancer drugs [1]. In this regard, natural compounds and derivatives are considered as a source of novel...

Peroxiredoxin (PRDX) proteins are involved in carcinogenesis. PRDX3, which is predominantly localized in mitochondria and up-regulated in several human cancers, seems to confer increased treatment resistance and aggressive phenotypes. This study examined the expression profile of PRDX3 and its possible clinical value in laryngeal squamous cell carcinoma (LSCC). The expression of PRDX3 in LSCC s...

Carbon dioxide (CO2) laser surgery as a conservative tool plays a peculiar role in the management of head and neck cancer. Numerous patients who were candidates for transoral laryngeal microsurgery have forced us to eliminate frozen-section evaluation of surgical margins and use a magnified view of the larynx. The present study evaluated surgeon-judged negative margins with permanent microscopi...

Laryngeal squamous cell carcinoma (SCC) is rare in children. Usually, laryngeal SCC in children has a poor prognosis. A 9-year-old boy is reported who was diagnosed as having poorly differentiated laryngeal squamous cell carcinoma with neck metastasis. This report aims to highlight the importance of a comprehensive knowledge of differential diagnosis, putting great attention to the onset of sym...
