1. Detection of somatic TP53 mutations and 17p deletions in patients with chronic lymphocytic leukemia: a review of the current methods
ABSTRACT Chronic lymphocytic leukemia is the most common hematologic malignancy among adults in Western countries. Several studies show that somatic mutations in the TP53 gene are present in up to 50% of patients with relapsed or refractory chronic lymphocytic leukemia. This study aims to review and compare the methods used to detect somatic TP53 mutations a

3. Neoplasias mamária e cerebelar metacrônicas em uma paciente jovem
Resumo Diversos fatores desencadeiam o desenvolvimento de mutações genéticas que são responsáveis por originar uma neoplasia. O meduloblastoma é uma neoplasia cerebelar maligna e invasiva que acomete crianças e adultos jovens. O carcinoma mucinoso é um tipo de câncer de mama especial por ser um subtipo atípico de carcinoma invasivo, que acomete com

4. Retrospective analysis of efficacy, safety, and prognostic factors in a cohort of Chinese hepatocellular carcinoma patients treated with drug-eluting bead transarterial chemoembolization
The aim of our study was to assess the efficacy, safety, and prognostic factors of drug-eluting bead transarterial chemoembolization (DEB-TACE) in Chinese hepatocellular carcinoma (HCC) patients. Patients (n=102) diagnosed as primary HCC were consecutively enrolled in this retrospective cohort study. Treatment responses were assessed following the modified R

5. Mutational landscape of head and neck squamous cell carcinomas in a South Asian population
Abstract Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer type globally and contributes significantly to burden of disease in South Asia. In Pakistan, HNSCC is among the most commonly diagnosed cancer in males and females. The increasing regional burden of HNSCC along with a unique set of risk factors merited a deeper investigati

6. Ecophysiology, genotoxicity, histopathology, and gene responses of naphthalene injected Colossoma macropomum (Cuvier, 1818) exposed to hypoxia
Abstract The present study aimed to evaluate the biological responses of Colossoma macropomum to naphthalene injection and subsequent hypoxia exposure, emphasizing the expression of the tumor suppressor gene tp53. Tambaquis were intraperitoneally injected with naphthalene (50 mg/kg) and, after 96 hours, the fish were transferred to respirometry chambers and,

7. Expressão de inibidores do ciclo celular na próstata canina com atrofia inflamatória proliferativa e carcinoma
RESUMO A expressão gênica de CDKN1A, CDKN1B e TP53, assim como imunomarcação de p21, p27 e p53 foram realizadas a fim de verificar o papel desses inibidores do ciclo celular na próstata canina com atrofia inflamatória proliferativa (PIA) e carcinoma prostático (PC). Foram obtidas70 amostras de próstata canina, sendo 15 de tecido normal, 30 de PIA e 2

8. Radiotherapy modulates expression of EGFR, ERCC1 and p53 in cervical cancer
Cervical cancer is a public health problem and the molecular mechanisms underlying radioresistance are still poorly understood. Here, we evaluated the modulation of key molecules involved in cell proliferation, cell cycle and DNA repair in cervical cancer cell lines (CASKI and C33A) and in malignant tissues biopsied from 10 patients before and after radiothe

9. O papel das mutações IDH1/2 na patogênese dos glioblastomas secundários
RESUMO Astrocitoma difuso e glioblastoma (GBM) constituem um grupo de neoplasias astrocíticas infiltrantes difusas, que mais comumente surgem nos hemisférios cerebrais de adultos. A prevalência da transformação maligna de astrocitoma difuso para astrocitoma anaplásico e GBM varia de 40% a 75% dos casos em diferentes séries. Distintas anormalidades gen

11. Exome sequence analysis of Kaposiform hemangioendothelioma: identification of putative driver mutations
Abstract BACKGROUND: Kaposiform hemangioendothelioma is a rare, intermediate, malignant tumor. The tumor's etiology remains unknown and there are no specific treatments. OBJECTIVE: In this study, we performed exome sequencing using DNA from a Kaposiform hemangioendothelioma patient, and found putative candidates for the responsible mutations. METHOD: The
