Alterações sistêmicas na assinatura do ciclo celular de pacientes com COVID-19

Com base nas perturbações fosfoproteômicas de moléculas associadas ao ciclo celular em células infectadas pelo coronavírus causador da síndrome respiratória aguda grave (SARSCoV)-2, a hipótese de inibidores do ciclo celular como uma terapia potencial para a doença de coronavírus 2019 (COVID-19...

The role of B3GNT3 as an oncogene in the growth, invasion and migration of esophageal cancer cells

Acta cir. bras; 38 (), 2023
Purpose: To investigate the role and mechanism of β1,3-N-acetylglucosaminyltransferase-3 gene (B3GNT3) in esophageal cancer (ESCA). Methods: The starBase database was used to evaluate the expression of B3GNT3. B3GNT3 function was measured using KYSE-30 and KYSE-410 cells of esophageal squamous cell carc...

The pattern of alternative splicing and DNA methylation alteration and their interaction in linseed (Linum usitatissimum L) response to repeated drought stresses

Biol. Res; 56 (), 2023
BACKGROUND: Drought stress has significantly hampered agricultural productivity worldwide and can also result in modifications to DNA methylation levels. However, the dynamics of DNA methylation and its association with the changes in gene transcription and alternative splicing (AS) under drought stress ...

Systems biology applied to the study of papaya fruit ripening: the influence of ethylene

Fruit ripening is a biochemical process that results in flavor, odor, texture, and color suitable for human consumption, in addition to providing access to important nutrients. Although ripening promotes sensory and nutritional increases in fruits, there is also an increased susceptibility to physical da...

Molecular characterization and functional analysis of scavenger receptor class B from black tiger shrimp (Penaeus monodon)

BACKGROUND: Scavenger receptor class B (SRB) is a multifunctional protein in animals that participates in physiological processes, including recognition of a wide range of ligands. Astaxanthin is a major carotenoid found in shrimp. However, the molecular mechanism of astaxanthin and SRB protein binding h...

Triple-negative breast cancer cells respond to T cells severely at the alternative splicing layer

BACKGROUND: Cross talk of tumor–immune cells at the gene expression level has been an area of intense research. However, it is largely unknown at the alternative splicing level which has been found to play important roles in the tumor–immune microenvironment. RESULTS: Here, we re-exploited one transc...

Transcriptional analysis of Rhazya stricta in response to jasmonic acid

BACKGROUND: Jasmonic acid (JA) is a signal transducer molecule that plays an important role in plant development and stress response; it can also efficiently stimulate secondary metabolism in plant cells. RESULTS: RNA-Seq technology was applied to identify differentially expressed genes and study the tim...

Profiles of immune infiltration in abdominal aortic aneurysm and their associated marker genes: a gene expression-based study

Braz. j. med. biol. res; 54 (11), 2021
Immune-mediated inflammation plays a key role in the pathology of abdominal aortic aneurysm (AAA). We aimed to use a computational approach to profile the immune infiltration patterns and related core genes in AAA samples based on the overexpression of gene signatures. The microarray datasets of AAA and ...

Odontogenic gene expression profile of human dental pulp-derived cells under high glucose influence: a microarray analysis

J. appl. oral sci; 29 (), 2021
Abstract Hyperglycemia, a major characteristic of diabetes, is considered to play a vital role in diabetic complications. High glucose levels have been found to inhibit the mineralization of dental pulp cells. However, gene expression associated with this phenomenon has not yet been reported. This is imp...

Identification and clinical validation of gene signatures with grade and survival in head and neck carcinomas

Braz. j. med. biol. res; 54 (11), 2021
This study aimed to explore gene expression profiles that drive malignancy from low- to high-grade head and neck carcinomas (HNC), as well as to analyze their correlations with survival. Gene expressions and clinical data of HNC were downloaded from the Gene Expression Omnibus (GEO) repository. The signi...
