Absence of significant genetic alterations in the VSX1, SOD1, TIMP3, and LOX genes in Brazilian patients with Keratoconus
(2021-01-01)
Purpose: To identify inherited or acquired mutations in the VSX1, SOD1, TIMP3 and LOX genes from the combined analysis of corneal and blood samples from patients with Keratoconus. Methods: The casuistry was consisted of ...
Expression of the sigma35 and cry2AB genes involved in Bacillus thuringiensis virulence
(Universidade de São Paulo (USP), Escola Superior de Agricultura Luiz de Queiroz (ESALQ), 2009-06-01)
Muitos genes estão envolvidos nos mecanismos de esporulação da bactéria Bacillus thuringiensis. A regulação e expressão desses genes resultam em uma produção massiva da proteína Cry, responsável pela morte das larvas de ...
Analysis of gene expression profiles under water stress in tolerant and sensitive sugarcane plants
(Elsevier B.V., 2009-02-01)
Water stress decreases plant productivity. To detect genes expressed under drought conditions, we performed a gene expression study using drought tolerant (SP83-5073) and sensitive (SP90-1638) sugarcane plants. Gene ...
rpb2 is a reliable reference gene for quantitative gene expression analysis in the dermatophyte Trichophyton rubrum
(INFORMA HEALTHCARELONDON, 2012)
The selection of reference genes used for data normalization to quantify gene expression by real-time PCR amplifications (qRT-PCR) is crucial for the accuracy of this technique. In spite of this, little information regarding ...

Synthesis and evaluation of diethylethylamine-chitosan for gene delivery: Composition effects on the in vitro transfection efficiency
(2013-02-08)
Chitosan has been indicated as a safe and promising polycation vector for gene delivery. However its low transfection efficiency has been a challenging obstacle for its application. To address this limitation, we synthesized ...
Genome-wide identification of multifunctional laccase gene family in Eucalyptus grandis: potential targets for lignin engineering and stress tolerance
(2020-06-01)
Key message: A survey of theEucalyptus grandis genome revealed the presence of 54 laccase genes. Their tissue-specific and stress-induced expression patterns suggest a role in lignification and adaptation to abiotic stresses. ...
Polymorphism analysis of the hsp70 stress gene in Broiler chickens (Gallus gallus) of different breeds
(Sociedade Brasileira de Genética, 2003-01-01)
The promoter region and the beginning of the coding region of the hsp70 stress gene were analysed in broiler chickens of a commercial breed (Hubbard-Pettersen), a breed selected for weight gain (PP1) and a non-selected ...
CITED GENE EXPRESSION IN PAPILLARY THYROID CARCINOMA: A POTENTIAL DIAGNOSTIC MARKER
(Univ Vale Paraiba-univap, 2019-12-01)
Thyroid cancer is the most common neoplasm of the endocrine system, with growing incidence in recent years. The diagnosis is performed mainly by the association of two methods: ultrasonography and fine needle aspiration ...
