Background: Laryngeal squamous cell carcinoma ranks second among head and neck squamous-cell carcinomas. Cancer stem cells can support cancer growth and malignant behavior. Therefore, cancer stem cells isolated from laryngeal squamous cell carcinoma tissue could be used to investigate the initiation, progression, and treatment strategies of this cancer. Methods: We isolated CD133-CD44-, CD133-C...

OBJECTIVE To survey the role of Helicobacter pylori at the tissue level as a cause of squamous cell carcinoma of the larynx. DESIGN A case-control study. SETTING In an Otolaryngology Ward at an academic university. SUBJECTS Patients with laryngeal cancer as cases and patients with benign laryngeal lesion as controls. MAIN OUTCOME MEASURE In all subjects, specimens of laryngeal tissue we...

17β-estradiol (E2) plays a key role in tumorigenesis by enhancing cell survivability and metastasis through its cytoplasmic receptors. Recently, a variant of estrogen receptor alpha, ERα36 has been implicated as a substantial mediator of E2's proliferative and antiapoptotic effects through rapid membrane-associated signaling, and cancers previously regarded as hormone-independent due to the abs...

Aims—To investigate whether anomalies of transforming growth factor â type II receptor (TGF-â RII) expression occur in the early stages of laryngeal carcinogenesis and to assess their importance in the development of laryngeal squamous cell carcinoma. TGF-â RII status was examined in laryngeal premalignant lesions coupled with malignant evolution and compared with a control group of similar les...

AIMS To investigate whether anomalies of transforming growth factor beta type II receptor (TGF-beta RII) expression occur in the early stages of laryngeal carcinogenesis and to assess their importance in the development of laryngeal squamous cell carcinoma. TGF-beta RII status was examined in laryngeal premalignant lesions coupled with malignant evolution and compared with a control group of si...

CD147, also named extracelluar matrix metalloproteinase inducer (EMMPRIN), is a member of the immunoglobulin family and a glycoprotein enriched on the surface of tumor cells, which promotes invasion, metastasis, growth and survival of malignant cells, and is known to confer resistance to some chemotherapeutic drugs. To determine the possible role of CD147 in the invasive properties of laryngeal...

Kindler syndrome is a rare autosomal recessive genodermatosis characterized by trauma-induced acral blisters in infancy and childhood, photosensitivity, and progressive poikiloderma. Other clinical features include chronic erosive gingivitis, dysphagia, esophageal and urethral strictures, ectropion, and an increased risk of mucocutaneous squamous cell carcinoma. We describe a patient with Kindl...
