Variation in genes involved in epigenetic processes offers insights into tropically adapted cattle diversity

Frontiers in Genetics, 2014
We evaluated the relevance of the BovineHD Illumina SNP chip with respect to genes involved in epigenetic processes. Genotypes for 729,068 SNP on two tropical cattle breeds of Australia were used: Brahman (n = 2,112) and Tropical Composite (n = 2,550 ...

No association of CTLA-4 polymorphisms with susceptibility to Behcet disease [PDF]

, 2009
Background: Cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) is a key negative regulator of T lymphocytes and has been shown to be associated with a number of autoimmune diseases. The present study was performed to assess the association between CTLA-

Approximate polymorphisms

Proceedings of the 54th Annual ACM SIGACT Symposium on Theory of Computing, 2022
For a function $g\colon\{0,1\}^m\to\{0,1\}$, a function $f\colon \{0,1\}^n\to\{0,1\}$ is called a $g$-polymorphism if their actions commute: $f(g(\mathsf{row}_1(Z)),\ldots,g(\mathsf{row}_n(Z))) = g(f(\mathsf{col}_1(Z)),\ldots,f(\mathsf{col}_m(Z)))$ for all $Z\in\{0,1\}^{n\times m}$.

Immunohistochemical Expression of CXCR4 on Breast Cancer and Its Clinical Significance

Analytical Cellular Pathology, 2015
Many tumor cells express chemokines and chemokine receptors, and, for this reason, these molecules can affect the tumor progression. It is known that breast cancer is a complex and heterogeneous neoplasia comprising distinct diseases, histological ...

Role of tumour necrosis factor gene polymorphisms (-308 and -238) in breast cancer susceptibility and severity [PDF]

, 2004
Introduction Genetic polymorphisms in the promoter region of the tumour necrosis factor (TNF) gene can regulate gene expression and have been associated with inflammatory and malignant conditions. We have investigated two polymorphisms in the promoter

Single nucleotide polymorphisms from Theobroma cacao expressed sequence tags associated with witches' broom disease in cacao [PDF]

, 2009
In order to increase the efficiency of cacao tree resistance to witches¿ broom disease, which is caused by Moniliophthora perniciosa (Tricholomataceae), we looked for molecular markers that could help in the selection of resistant cacao genotypes.

Associação dos polimorfismos dos genes TGF-beta1, CD14, IL-4, IL-4R e ADAM33 com a gravidade da asma em crianças e adolescentes Association of TGF-beta1, CD14, IL-4, IL-4R and ADAM33 gene polymorphisms with asthma severity in children and adolescents

Jornal de Pediatria, 2008
OBJETIVO: Verificar, em uma amostra de pacientes com asma atópica persistente leve, moderada e grave, a associação entre os polimorfismos dos genes fator de crescimento transformante-beta1 (TGF-beta1) (C-509T e T869C), CD14 (C-159T), IL-4 (C-590T), IL-4R

ACE Polymorphisms [PDF]

Circulation Research, 2006
Angiotensin converting enzyme (ACE) plays an essential role in two physiological systems, one leading to the production of angiotensin II and the other to the degradation of bradykinin. The wide distribution and multifunctional properties of these peptides suggest that ACE could be involved in various pathophysiological conditions.

Frequencies of 23 functionally significant variant alleles related with metabolism of antineoplastic drugs in the Chilean population: comparison with Caucasian and Asian populations

Frontiers in Genetics, 2012
Cancer is a leading cause of death worldwide. The cancer incidence rate in Chile is 133.7/100,000 inhabitants and it is the second cause of death, after cardiovascular diseases.

CX3CR1 Polymorphisms are associated with atopy but not asthma in German children [PDF]

, 2007
Chemokines and their receptors are involved in many aspects of immunity. Chemokine CX3CL1, acting via its receptor CX3CR1, regulates monocyte migration and macrophage differentiation as well as T cell-dependent inflammation.
