Zebrafish ambra1b knockout reveals a novel role for Ambra1 in primordial germ cells survival, sex differentiation and reproduction

Biol. Res; 56 (), 2023
BACKGROUND: AMBRA1 is an intrinsically disordered protein, working as a scaffold molecule to coordinate, by protein-protein interaction, many cellular processes, including autophagy, mitophagy, apoptosis and cell cycle progression. The zebrafish genome contains two ambra1 paralogous genes (a and b), both...

Oncogenic circDHTKD1 promotes tumor growth and metastasis of oral squamous cell carcinoma in vitro and in vivo via upregulating miR-326-mediated GAB1

Braz. j. med. biol. res; 54 (10), 2021
Circular RNAs (circRNAs) have been extensively elucidated with regard to their significant implications in oral squamous cell carcinoma (OSCC). This study performed the functional investigation of circRNA dehydrogenase E1 and transketolase domain containing 1 (circDHTKD1) in OSCC. RNA expression levels o...

Angioid streaks and optic disc drusen in cherubism: a case report

Arq. bras. oftalmol; 83 (6), 2020
ABSTRACT A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed b...

DC-STAMP and tace levels are higher in patients with periodontitis

Braz. dent. j; 31 (2), 2020
Abstract Although periodontitis is one of the commonest infectious inflammatory diseases in humans, the mechanisms involved with its immunopathology remain ill understood. Numerous molecules may induce inflammation and lead to bone resorption, secondary to activation of monocytes into osteoclasts. TACE (...

The branched-chain amino acid transaminase 1 -23c/g polymorphism confers protection against acute coronary syndrome

Rev. invest. clín; 72 (1), 2020
ABSTRACT Background: Previous studies have shown an association between polymorphisms of the BAT1-NF-κB inhibitor-like-1 (NFKBIL1)-LTA genomic region and susceptibility to myocardial infarction and acute coronary syndrome (ACS). Objective: The objective of the study was to study the role of three ...

Serum sclerostın levels ın chronıc otıtıs medıa wıth and wıthout cholesteatoma

SUMMARY OBJECTIVE Sclerostin is a glycoprotein that plays a catabolic role in bone and is involved in the regulation of bone metabolism by increasing the osteoclastic bone resorption. In this study, serum sclerostin levels were measured in chronic otitis media (COM) with and without cholesteatoma, assu...

Linc-OIP5 in the breast cancer cells regulates angiogenesis of human umbilical vein endothelial cells through YAP1/Notch/NRP1 signaling circuit at a tumor microenvironment

Biol. Res; 53 (), 2020
BACKGROUND: LincRNAs have been revealed to be tightly associated with various tumorigeneses and cancer development, but the roles of specific lincRNA on tumor-related angiogenesis was hardly studied. Here, we aimed to investigate whether linc-OIP5 in breast cancer cells affects the angiogenesis of HUVECs...

Dact1 involvement in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation by regulating cx43

Abstract Objective: To determine the role of the dishevelled binding antagonist of beta catenin 1 (DACT1) in the cytoskeletal arrangement of cardiomyocytes in atrial fibrillation (AF). Methods: The DACT1 expression and its associations with the degree of fibrosis and β-catenin in valvular disease ...

YAP activation promotes the transdifferentiation of cardiac fibroblasts to myofibroblasts in matrix remodeling of dilated cardiomyopathy

Braz. j. med. biol. res; 52 (1), 2019
Yes-associated protein (YAP) is an important regulator of cellular proliferation and transdifferentiation. However, little is known about the mechanisms underlying myofibroblast transdifferentiation in dilated cardiomyopathy (DCM). We investigated the role of YAP in the pathological process of cardiac ma...

Isolation and characterization of a human cementocyte-like cell line, HCY-23

Abstract Cementum is the mineralized tissue covering the tooth root that functions in tooth attachment and post-eruptive adjustment of tooth position. It has been reported to be highly similar to bone in several respects but remains poorly understood in terms of development and regeneration. Here, we inv...
