Polymorphisms of matrix metalloproteinase-7 and -9 are associated with oral tongue squamous cell carcinoma

Abstract Matrix degradation is an important event in the progression, invasion and metastasis of malignant head and neck lesions. Imbalances, mutations and polymorphisms of MMPs and their inhibitors are observed in several cancer subtypes. The aim of this study was to evaluate the association of the MMP-...

Oncogenic circDHTKD1 promotes tumor growth and metastasis of oral squamous cell carcinoma in vitro and in vivo via upregulating miR-326-mediated GAB1

Braz. j. med. biol. res; 54 (10), 2021
Circular RNAs (circRNAs) have been extensively elucidated with regard to their significant implications in oral squamous cell carcinoma (OSCC). This study performed the functional investigation of circRNA dehydrogenase E1 and transketolase domain containing 1 (circDHTKD1) in OSCC. RNA expression levels o...

Hsa_circ_0002162 has a critical role in malignant progression of tongue squamous cell carcinoma through targeting miR-33a-5p

Braz. j. med. biol. res; 54 (5), 2021
The aim of this study was to explore the effect of hsa_circ_0002162 on regulating cell proliferation, apoptosis, and invasion, and investigate its potential target microRNA (miRNA) in tongue squamous cell carcinoma (TSCC). Hsa_circ_0002162 expression was detected in human TSCC cell lines and human oral k...

MET overexpression and intratumor heterogeneity in esophageal squamous cell carcinoma

Braz. j. med. biol. res; 54 (8), 2021
Esophageal squamous cell carcinoma (ESCC) is among the ten most frequent and deadly cancers, without effective therapies for most patients. More recently, drugs targeting deregulated growth factor signaling receptors have been developed, such as HGF-MET targeted therapy. We assessed MET and HGF genetic a...

Anti-micro rna-221 a promising genetic therapy of oral squamous cell carcinoma (scc-25)

Braz. dent. j; 31 (6), 2020
Abstract Micro-RNA-221(miR-221) is one of oncogenic miRNAs that plays a vital role in the development and progression of oral cancers. The aim of this study is to introduce a new gene therapy for oral squamous cell carcinoma by blocking the expression of oncogenic miR-221 by its inhibitor. The present wo...

LINC00355 promoted the progression of lung squamous cell carcinoma through regulating the miR-466/LYAR axis

Braz. j. med. biol. res; 53 (12), 2020
LINC00355 has been reported aberrantly over-expressed and associated with poor prognosis in various types of cancer. However, reports regarding the effect of LINC00355 on lung squamous cell carcinoma (SCC) are rare. This study aimed to explore the function of LINC00355 in the development and progression ...

Squamous cell lung cancer: genomic evolution and personalized therapy

Salud pública Méx; 61 (3), 2019
Abstract: Objective: To review the state-of-the-art in relation to the current information on squamous cell lung cancer (SCLC). We describe the genetic anomalies reported, their effect, and finally the most promising therapeutic agents. Materials and methods: We reviewed published articles in peer-re...

Análise imunoistoquímica da expressão de PD-L1 em células tumorais e células T nos carcinomas de células escamosas do pênis

Introdução: A neoplasia do pênis é uma doença rara, sendo mais frequente nos países em desenvolvimento. Representa 0,4%dos tumores malignos dos homens nos EUA e 2,1% no Brasil, sendo mais prevalente nas regiões norte e nordeste. O carcinoma epidermóide representa aproximadamente 95% das neoplasia...

Genomic profile of a squamous cell carcinoma ex pleomorphic adenoma compared to a head and neck squamous cell carcinoma

Immunohistochemical WWOX expression and association with angiogenesis, p53 expression, cell proliferation and clinicopathological parameters in cervical cancer

Abstract Objective The current study evaluated the expression of WW domain-containing oxidoreductase (WWOX), its association with clinicopathological features and with p53, Ki-67 (cell proliferation) and CD31 (angiogenesis) expression in patients with invasive cervical squamous cell carcinoma (ICSCC). ...
