Inhibition of Proliferation, Migration, and Invasion of Keloid Fibroblasts By miR-183-5p Through Downregulating EGR1

Int. j. morphol; 41 (6), 2023
SUMMARY: Keloid scar is a unique benign fibroproliferative tumor of the human skin. Previously, it was reported that early growth response 1 (EGR1), a transcription factor, promotes keloid fibrosis; however, the mechanism by which EGR1 modulates keloid formation was not elaborated. In this research, the ...

Unveiling the role of osteoblastic micro RNAs in the skeleton: from biological functions to therapeutic potential

Actual. osteol; 19 (1), 2023
MicroRNAs (miRNAs) are small non-coding RNA molecules that play critical roles in post-transcriptional gene regulation. They function by binding to target messenger RNA (mRNA) molecules, leading to their degradation or inhibiting their translation i...

Molecular mechanisms in the process of re-epithelization in wound healing and the action of honey in keratinocytes

Int. j. morphol; 38 (6), 2020
SUMMARY: The treatment of chronic wounds has become a public health issue in recent years mainly due to comorbidities associated with an older population and bacterial resistance. Honey has emerged as an alternative treatment for chronic wounds but lack of knowledge of its mechanism of actionin the treat...

Silencing of circular RNA ANRIL attenuates oxygen-glucose deprivation and reoxygenation-induced injury in human brain microvascular endothelial cells by sponging miR-622

Biol. Res; 53 (), 2020
BACKGROUND: Circular RNA (circRNA) is highly expressed in the brain tissue, but its molecular mechanism in cerebral ischemia-reperfusion remains unclear. Here, we explored the role and underlying mechanisms of circRNA antisense non-coding RNA in the INK4 locus (circ_ANRIL) in oxygen-glucose deprivation a...

MiR-128 suppresses metastatic capacity by targeting metadherin in breast cancer cells

Biol. Res; 53 (), 2020
BACKGROUND: Breast cancer, the most common cancer in women worldwide, causes the vast majority of cancer-related deaths. Undoubtedly, tumor metastasis and recurrence are responsible for more than 90 percent of these deaths. MicroRNAs are endogenous noncoding RNAs that have been integrated into almost all...

Micro-ARNs y células óseas
Micro RNAs and bone cells

Actual. osteol; 16 (3), 2020
Los micro-ARNs (miARNs) son pequeñas moléculas de ARN no codificante (de aproximadamente 15-25 nucleótidos), que regulan la expresión de genes involucrados en numerosas funciones biológicas, a través de la inhibición o degradación de un ARN mensajero diana. La homeostasis ósea se mantiene por el...

MicroRNA-221 promotes cell proliferation, migration, and differentiation by regulation of ZFPM2 in osteoblasts

Braz. j. med. biol. res; 51 (12), 2018
Bone fracture is a common medical condition, which may occur due to traumatic injury or disease-related conditions. Evidence suggests that microRNAs (miRNAs) can regulate osteoblast differentiation and function. In this study, we explored the effects and mechanism of miR-221 on the growth and migration o...

Propofol attenuates sepsis-induced acute kidney injury by regulating miR-290-5p/CCL-2 signaling pathway

Braz. j. med. biol. res; 51 (11), 2018
Previous studies have indicated that propofol has immunomodulatory and antioxidative properties. However, the renoprotection effect and the precise mechanisms of propofol in sepsis-induced renal injury remain unclear. The purpose of the present study was to investigate the role of miR-290-5p/CCL-2 signal...

Role of non-coding RNAs in non-aging-related neurological disorders

Braz. j. med. biol. res; 51 (8), 2018
Protein coding sequences represent only 2% of the human genome. Recent advances have demonstrated that a significant portion of the genome is actively transcribed as non-coding RNA molecules. These non-coding RNAs are emerging as key players in the regulation of biological processes, and act as "fine-tun...

miR-483-5p promotes prostate cancer cell proliferation and invasion by targeting RBM5

Int. braz. j. urol; 43 (6), 2017
ABSTRACT Objective: miR-483-5p has been identified as a miRNA oncogene in certain cancers. However, its role in prostate cancer has not been sufficiently investigated. In this study, we investigated the role of miR-483-5p in prostate cancer and examined RBM5 regulation by miR-483-5p. Material and metho...
