Objective: To describe the mortality trend from all causes of cancer and the five main causes in the state of Mato Grosso, Brazil, from 2000 to 2015. Methods: This is a descriptive, ecological, time series study, with data referring to deaths of residents of Mato Grosso due to neoplasms (ICD-10 codes C00 to C97), from the Mortality Information System (SIM). Time trend analyzes of the standardized mortality rate from all causes of cancer and five specific causes of cancer (lung, prostate, breast, colorectal and cervix) for the state and according to macroregions (South, West, North, East and Center -North) were performed using linear regression (p-value<0.05). Results: From 2000 to 2015, 28,525 deaths from all causes of cancer in residents of the state of Mato Grosso were recorded. An increasing trend was observed for all causes of cancer, in addition to lung, breast and colorectal cancers. Southern and Northern macroregions showed an increasing trend for all causes, breast and colorectal; North-Central for breast and colorectal. East was increasing for all causes, prostate and colorectal, and decreasing for cervix. Conclusions: In the state of Mato Grosso, there was an increasing trend in mortality from all causes of cancer and from specific causes, with emphasis on breast and colorectal cancer in most macroregions.

Objetivo: Descrever a tendência da mortalidade por todas as causas de câncer e das cinco principais causas no Estado de Mato Grosso, Brasil, no período 2000 a 2015. Métodos: Trata-se de um estudo descritivo, ecológico, do tipo série temporal, com dados referentes aos óbitos de residentes de Mato Grosso por neoplasias (códigos C00 a C97 da CID-10), provenientes do Sistema de Informações sobre Mortalidade (SIM). A tendência temporal da taxa de mortalidade padronizada de todas as causas de câncer e cinco causas específicas de câncer (pulmão, próstata, mama feminina, colorretal e colo do útero) para o estado e segundo macrorregiões (Sul, Oeste, Norte, Leste e Centro-Norte) foi analisada por meio de regressão linear (p-valor<0,05). Resultados: De 2000 a 2015, ocorreram 28.525 óbitos por todas as causas de câncer em residentes no Estado de Mato Grosso. Tendência crescente foi observada para todas as causas de câncer, além dos cânceres de pulmão, mama e colorretal. Macrorregiões Sul e Norte apresentaram tendência crescente para todas as causas, mama e colorretal; Centro-Norte para mama e colorretal. Na Macrorregião Leste foi crescente para todas as causas, próstata e colorretal, e decrescente para colo do útero. Conclusões: No Estado de Mato Grosso, verificou-se tendência crescente da mortalidade por todas as causas de câncer e por causas específicas, com destaque para mama e colorretal na maioria das macrorregiões.

ABSTRACT: Objective: To describe the mortality trend from all cancers and the five main ones in the state of Mato Grosso, Brazil, from 2000 to 2015. Methods: This is a descriptive, ecological, time series study, with data referring to deaths of residents of Mato Grosso due to cancer (ICD-10 codes C00 to C97), from the Mortality Information System (SIM). Time trend analyses of the standardized mortality rate from all cancers and five specific cancers (lung, prostate, breast, colorectal and cervical) for the state and according to macroregion (South, West, North, East and Center-North) were performed using linear regression (p<0.05). Results: From 2000 to 2015, 28,525 deaths from all cancers in residents of the state of Mato Grosso were recorded. An increasing trend was observed for all cancers, in addition to lung, breast and colorectal cancers. The South and North macroregions showed an increasing trend for all cancers, breast and colorectal, and Center-North for breast and colorectal. East showed an increasing trend for all cancers, prostate and colorectal, and decreasing for cervical. Conclusion: In the state of Mato Grosso, there was an increasing trend in mortality for all cancers and from specific ones, with emphasis on breast and colorectal cancer in most macroregions.

Abstract Specific pathogenic mutations associated with breast cancer development can vary between ethnical groups. One example is BRCA1 c.5266dupC that was first described as a founder mutation in the Ashkenazi Jewish population, but was later also found in other populations. In Brazil, this mutation corresponds to 20% of pathogenic BRCA1 variants reported. Our objective was to investigate the haplotype component of a group of Brazilian families who inherited c.5266dupC in the BRCA1 gene and to verify the ancestry contribution from European, African, and Amerindian origins. Fourteen probands carrying c.5266dupC and 16 relatives (carriers and non-carriers) were investigated. The same haplotype was observed segregating within all the families analyzed, revealing no recombinants in a region of 0.68 Mb. Ancestry analysis demonstrated that the European component was predominant among probands. The BRCA1 c.5266dupC analysis indicates that there was a founder effect in the Brazilian population.

Abstract The DNA Damage Response (DDR) is a complex network of biological processes that protect cells from accumulating aberrant DNA structures, thereby maintaining genomic stability and, as a consequence, preventing the development of cancer and other diseases. The DDR pathway is coordinated by a signaling cascade mediated by the PI3K-like kinases (PIKK) ATM and ATR and by their downstream kinases CHK2 and CHK1, respectively. Together, these kinases regulate several aspects of the cellular program in response to genomic stress. Much of our understanding of these kinases came from studies performed in the 1990s using yeast as a model organism. The purpose of this review is to present a historical perspective on the discovery of the DDR kinases in yeast and the importance of this model for the identification and functional understanding of their mammalian orthologues.
