Reporte de caso de feocromocitoma bilateral asociado a mutación del gen TMEM127. Primer caso chileno

Rev. med. Chile; 150 (8), 2022
Up to 40% of Pheochromocytoma/paraganglioma syndromes are associated with germline mutations. Therefore, they are considered familial and heritable. We report a 65 year old woman with hypertension, bilateral adrenal nodules found in the CT scan and elevated urinary metanephrines. Her genetic testing show...

Bovine TMEM95 gene: Polymorphisms detecting in five Chinese indigenous cattle breeds and their association with growth traits

BACKGROUND: Transmembrane protein 95 (TMEM95) plays a role in male fertility. Previous studies showed that genes with a significant impact on reproductive traits can also affect the growth traits of livestock. Thus, we speculated that the genetic variation of TMEM95 gene may have effects on growth traits...

Complete screening of exons 2, 3, and 4 of kras and nras genes reveals a higher number of clinically relevant mutations than food and drug administration quantitative polymerase chain reaction-based commercial kits

Rev. invest. clín; 72 (6), 2020
Abstract Background: The presence of clinically relevant mutations in KRAS and NRAS genes determines the response of anti-epidermal growth factor receptor antibody therapy for metastatic colorectal cancer (mCRC). The only quantitative polymerase chain reaction (qPCR)-based diagnostic tests approved by t...

Pioneering studies on monogenic central precocious puberty

ABSTRACT Pubertal timing in humans is determined by complex interactions including hormonal, metabolic, environmental, ethnic, and genetic factors. Central precocious puberty (CPP) is defined as the premature reactivation of the hypothalamic-pituitary-gonadal axis, starting before the ages of 8 and 9 yea...

Phylogeography of msp4 genotypes of Anaplasma marginale in beef cattle from the Brazilian Pantanal

Abstract The msp4 gene of A. marginale is unicodon, stable and mostly homogeneous, being considered as a useful marker for phylogeographic characterization of this bacterium. The objective of this work was to analyze the phylogeography of A. marginale based on the msp4 gene in beef cattle from the Brazil...

The virulence of Streptococcus pneumoniae partially depends on dprA

Braz. j. microbiol; 48 (2), 2017
Abstract Streptococcus pneumoniae is one of the most frequent opportunistic pathogens worldwide. DNA processing protein A (DprA) is an important factor involved in bacterial uptake and DNA integration into bacterial genome, but its role in S. pneumoniae virulence remains unclear. The aim of this study wa...

Differences in Hepatic Expression of Iron, Inflammation and Stress-Related Genes in Patients with Nonalcoholic Steatohepatitis

Ann. hepatol; 16 (1), 2017
Abstract: Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease worldwide. We have previously shown that hepatic reticuloendothelial system (RES) iron deposition is associated with an advanced degree of nonalcoholic steatohepatitis (NASH) in humans. In this study, we ...

Identificación de variantes del gen NPHS2 en niños con síndrome nefrótico corticorresistente

Rev. chil. pediatr; 87 (1), 2016
Resumen: La podocina es una proteína localizada en el diafragma de filtración glomerular donde participa en la regulación de la filtración glomerular. Las mutaciones del gen NPHS2, que codifica a la podocina, son la principal causa de síndrome nefrótico corticorresistente (SNCR) autosómico recesiv...

Olfactomedin-like 2 A and B (OLFML2A and OLFML2B) expression profile in primates (human and baboon)

Biol. Res; 49 (), 2016
BACKGROUND: The olfactomedin-like domain (OLFML) is present in at least four families of proteins, including OLFML2A and OLFML2B, which are expressed in adult rat retina cells. However, no expression of their orthologous has ever been reported in human and baboon. OBJECTIVE: The aim of this study was to ...
