LncRNA LINC00483 promotes gastric cancer development through regulating MAPK1 expression by sponging miR-490-3p

Biol. Res; 53 (), 2020
BACKGROUND: Previous studies have shown that long noncoding RNA (IncRNA) LINC00483 was aberrantly expressed in human cancers, including gastric cancer. However, the regulatory mechanism of this IncRNA in gastric cancer remains largely unknown. The present study aimed to investigate the effect of LINC0048...

Knockdown of lncRNA TUG1 inhibits hippocampal neuronal apoptosis and participates in aerobic exercise-alleviated vascular cognitive impairment

Biol. Res; 53 (), 2020
OBJECTIVES: Our previous study indicated that aerobic exercise relieves cognitive impairment in patients with vascular cognitive impairment (VCI) via regulating brain-derived neurotrophic factor (BDNF), but the mechanism is not yet clear. This study aimed to explore whether lncRNA taurine upregulated gen...

lncRNA CCAT1 promotes bladder cancer cell proliferation, migration and invasion

Int. braz. j. urol; 45 (3), 2019
ABSTRACT Objective: To study the expression patterns of long noncoding RNA (lncRNA) colon cancer-associated transcript 1 (CCAT1) and the changes in cell proliferation, apoptosis, migration and invasion induced by silencing CCAT1 in bladder cancer cells. Materials and Methods: The expression levels of C...

Los ARNs no codificantes largos y su vinculación con las patologías testiculares

Si bien la porción del genoma destinada a la síntesis de proteínas es muy pequeña, actualmente se sabe que casi todo el genoma se expresa bajo forma de ARNs no codificantes. Entre dichos ARNs se encuentran los ARNs no codificantes largos (lncRNAs). Aunque los lncRNAs han sido muy poco estudiados, rec...

Downregulation of lncrna uca1 as a diagnostic and prognostic biomarker for ovarian endometriosis

SUMMARY OBJECTIVE: Ovarian endometriosis seriously affects the quality of life of females, and long non-coding RNA lncRNA urothelial carcinoma-associated 1 (UCA1) plays pivotal roles in the pathogenesis of various ovarian diseases. However, the involvement of lncRNA UCA1 in ovarian endometriosis remains...

The overexpression of lncRNA H19 as a diagnostic marker for coronary artery disease

SUMMARY OBJECTIVE: Our study aimed to investigate the diagnostic value of lncRNA H19 for coronary artery disease (CAD) and to explore its possible mechanisms. Methods: A total of 30 CAD patients and 30 healthy individuals, as well as patients with different cardiovascular diseases, were included in thi...

Polydatin protects H9c2 cells from hypoxia-induced injury via up-regulating long non-coding RNA DGCR5

Braz. j. med. biol. res; 52 (12), 2019
Polydatin (PD), a monocrystalline polyphenolic drug mainly found in the roots of Polygonum cuspidatum, has various pharmacological activities. Long non-coding RNAs (lncRNA) DiGeorge syndrome critical region gene 5 (DGCR5) was found to participate in the suppression of multiple cancers. Here, we proposed ...

Baicalein restrains proliferation, migration, and invasion of human malignant melanoma cells by down-regulating colon cancer associated transcript-1

Braz. j. med. biol. res; 52 (12), 2019
Baicalein (BAI) is an acknowledged flavonoids compound, which is regarded as a useful therapeutic pharmaceutical for numerous cancers. However, its involvement in melanoma is largely unknown. This study aimed to examine the anti-melanoma function of BAI and unraveled the regulatory mechanism involved. A3...

Downregulation of lncRNA CCDC26 contributes to imatinib resistance in human gastrointestinal stromal tumors through IGF-1R upregulation

Braz. j. med. biol. res; 52 (6), 2019
Imatinib is the first line of therapy for patients with metastatic or gastrointestinal stromal tumors (GIST). However, drug resistance limits the long-term effect of imatinib. Long non-coding RNAs (lncRNAs) are emerging as key players in regulating drug resistance in cancer. In this study, we investigate...

Diagnostic value of circulating lncRNA ANRIL and its correlation with coronary artery disease parameters

Braz. j. med. biol. res; 52 (8), 2019
This study aimed to detect the expression of the long non-coding RNA (lncRNA) antisense non-coding RNA in the INK4 locus (ANRIL) and evaluate its correlation with disease risk, stenosis degree, inflammation, as well as overall survival (OS) in coronary artery disease (CAD) patients. A total of 230 patien...
