Effect of baicalein on migration and invasion of cutaneous squamous cell carcinoma cells and the underlying mechanism

This study aimed to investigate the effect of baicalein on migration and invasion of human cutaneous squamous cell carcinoma A431 cells. A431 cells were incubated with baicalein with concentrations of 0 (control), 2, 4, 8, 16 and 32 μmol/L, respectively. The cell proliferation...

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 ...

Effect of Survivin Down-Regulation by Egr1-Survivin shRNA Combined with Radiotherapy on Radiosensitivity of Esophageal Squamous Carcinoma

Int. j. morphol; 41 (6), 2023
SUMMARY: This study is to investigate the effect of survivin down-regulation by Egr1-survivin shRNA combined with radiotherapy on the apoptosis and radiosensitivity of esophageal squamous cell carcinoma ECA109 and KYSE150 cells. ECA109 and KYSE150 cells were transfected with Egr1-survivin shRNA, and then...

Down-regulation of complement genes in lipopolysaccharide-challenged zebrafish (Danio rerio) larvae exposed to Indonesian propolis

Braz. j. biol; 83 (), 2023
Abstract Although propolis has been reported for having anti-inflammatory activities, its effects on complement system has not been much studied. This research was conducted to find out the effects of Indonesian propolis on the expression levels of C3, C1r/s, Bf, MBL, and C6 in zebrafish larvae which wer...

ADAMTS proteoglycanases downregulation with impaired oocyte quality in PCOS

ABSTRACT Objective: A disintegrin and metalloproteinase with thrombospondin motifs 4 (ADAMTS-4) and ADAMTS-5 normal expression levels are essential for ovulation and subsequent fertilization. The objective of the present study was to assess expression pattern of these genes in cumulus cells (CCs) taken ...

Melittin suppresses growth and induces apoptosis of non-small-cell lung cancer cells via down-regulation of TGF-β-mediated ERK signal pathway

Braz. j. med. biol. res; 54 (2), 2021
The purpose of this study was to investigate the anti-cancer effect of melittin on growth, migration, invasion, and apoptosis of non-small-cell lung cancer (NSCLC) cells. This study also explored the potential anti-cancer mechanism of melittin in NSCLC cells. The results demonstrated that melittin suppre...

Down-regulation of HCP5 inhibits cell proliferation, migration, and invasion through regulating EPHA7 by competitively binding miR-101 in osteosarcoma

Braz. j. med. biol. res; 54 (2), 2021
Patients with osteosarcoma (OS) usually have poor overall survival because of frequent metastasis. Long non-coding RNAs (lncRNAs) have been reported to be associated with tumorigenesis and metastasis. In this study, we investigated the expression and roles of lncRNA human histocompatibility leukocyte ant...

microRNA-130b downregulation potentiates chondrogenic differentiation of bone marrow mesenchymal stem cells by targeting SOX9

Braz. j. med. biol. res; 54 (4), 2021
Osteoarthritis (OA) is a chronic health condition. MicroRNAs (miRs) are critical in chondrocyte apoptosis in OA. We aimed to investigate the mechanism of miR-130b in OA progression. Bone marrow mesenchymal stem cells (BMSCs) and chondrocytes were first extracted. Chondrogenic differentiation of BMSCs was...

Effects of Arf6 downregulation on biological characteristics of human prostate cancer cells

ABSTRACT Objective To evaluate the effects of Arf6 downregulation on human prostate cancer cells. Materials and Methods The effects of Arf6 downregulation on cell proliferation, migration, invasion and apoptosis were assessed by MTT, BrdU, scratch, Transwell assays and flow cytometry respectively. AK...
