Antecedente de grado de expresividad de p53 en carcinomas basocelulares como predictor de recurrencia
Background of p53 expressivity grade in basal cell carcinomas as a predictor of recurrence

Cambios rev. méd; 22 (2), 2023; 22 (2), 2023; 22 (2), 2023
INTRODUCCIÓN. El gen Tp53 proporciona instrucciones para producir proteína tumoral 53. El Tp53 es un gen supresor tumoral que protege el ciclo celular, reparando el ADN o activando la apoptosis. Es clave en la carcinogénesis del carcinoma basocelular, patología que cobra relevancia en Ecuador, debido...

p53 & Cyclin D1 expression in surgically resected clear margins of oral squamous cell carcinoma

Braz. j. oral sci; 20 (), 2021
Oral squamous cell carcinoma (OSCC) is one of the most well-known malignancies that affect the human population worldwide. The early diagnosis and early intervention of OSCC help improve the survival rate of the patients. The tumour free surgical margins are a positive prognostic factor for recurrence-fr...

Quercetin Inhibits ROS-p53-Bax-caspase-3 axis of apoptosis and augments gonadotropin and testicular hormones in chronic unpredictable stress-Induced testis injury

Int. j. morphol; 39 (3), 2021
SUMMARY: A large body of evidence supports the protective role of the flavonol antioxidant compound quercetin in mammals. We tested the hypothesis that quercetin can protect against the hypothalamus-pituitary-gonadal (HPG) axis defect like a reduction in gonadotropins and testicular hormones and abnormal...

Modification in clic4 expression is associated with p53, tgf-β, tnf-α and myofibroblasts in lip carcinogenesis

Braz. dent. j; 31 (3), 2020
Abstract Chloride intracellular channel-4 (CLIC4) is regulated by p53 and tumor necrosis factor-α (TNF-α), it is linked to the increase of transforming growth factor-β (TGF-β), and myofibroblastic differentiation in skin carcinogenesis. This study analyzed the immunoexpression of CLIC...

Inmunohistoquímica de p16 y p53 en cáncer de vulva
Immunohistochemistry of p16 and p53 in vulvar cancer

Medicina (B.Aires); 80 (2), 2020
El carcinoma escamoso vulvar puede desarrollarse de manera asociada o independiente a la infección por HPV. La relación entre la patogénesis, la clasificación, el perfil inmunohistoquímico, y el pronóstico ha sido estudiada con algunas discrepancias. El objetivo del trabajo fue observar la concorda...

Marcadores moleculares para diferenciação diagnóstica do carcinoma urotelial

Rev. bras. anal. clin; 52 (1), 2020
A maioria das neoplasias na bexiga tem início no urotélio. O carcinoma das células de transição é o mais comum. A citologia urinária juntamente com a cistoscopia, permanece como ferramenta de diagnóstico e monitoração. Alguns marcadores potenciais foram reconhecidos em espécimes de citologia u...

Functional and genomic characterization of three novel cell lines derived from a metastatic gallbladder cancer tumor

Biol. Res; 53 (), 2020
BACKGROUND: Gallbladder cancer (GBC) is the most common tumor of the biliary tract. The incidence of GBC shows a large geographic variability, being particularly frequent in Native American populations. In Chile, GBC represents the second cause of cancer-related death among women. We describe here the es...

External validation of nomogram to predict inguinal lymph node metastasis in patients with penile cancer and clinically negative lymph nodes

Int. braz. j. urol; 45 (4), 2019
ABSTRACT Introduction Penile cancer (PC) occurs less frequently in Europe and in the United States than in South America and parts of Africa. Lymph node (LN) involvement is the most important prognostic factor, and inguinal LN (ILN) dissection can be curative; however, ILN dissection has high morbidity...

Immunoexpression of TS, p53, COX2, EGFR, MSH6 and MLH1 biomarkers and its correlation with degree of differentiation, tumor staging and prognostic factors in colorectal adenocarcinoma: a retrospective longitudinal study

Säo Paulo med. j; 137 (1), 2019
ABSTRACT BACKGROUND: There are cases of colorectal tumors that, although small, show more aggressive evolution than large tumors. This motivated us to study whether there are any proteins capable of alerting about these changes. The aim here was to correlate the immunoexpression of the TS, p53, COX2, E...

Patterns of proliferation and apoptosis in different subtypes of basal cell carcinoma, adjacent epidermis, and recurrent forms
