Tbx1 is required for second heart field proliferation in zebrafish [PDF]

Developmental Dynamics, 2013
Background: The mammalian outflow tract (OFT) and primitive right ventricle arise by accretion of newly differentiated cells to the arterial pole of the heart tube from multi‐potent progenitor cells of the second heart field (SHF). While mounting evidence suggests that the genetic pathways regulating SHF development are highly conserved in zebrafish ...

Mutation Analysis of TBX1 in Children with Conotruncal Heart Anomalies [PDF]

The Indian Journal of Pediatrics, 2015
To the Editor: Conotruncal heart anomalies (CTA) are structural malformations involving the outflow tract. While the exact incidence of CTA in India is not known, it remains the most common type of structural birth defect with a major impact on pediatric morbidity and mortality.

Tbx1 orchestrates an immune niche that safeguards a broken heart

Immunity, 2023
Cardiac lymphatics cooperate with the reparative immune response in myocardial healing after infarction. In this issue of Immunity, Wang and colleagues discover a mechanism underlying this cooperation, dependent on the transcription factor Tbx1 and responsible for the creation of an immunosuppressive niche that mitigates autoimmunity.

Tbx1 represses Mef2c gene expression and is correlated with histone 3 deacetylation of the anterior heart field enhancer

Disease Models & Mechanisms, 2018
The TBX1 gene is haploinsufficient in 22q11.2 deletion syndrome (22q11.2DS), and genetic evidence from human patients and mouse models points to a major role of this gene in the pathogenesis of this syndrome.

Rebalancing gene haploinsufficiency in vivo by targeting chromatin

Nature Communications, 2016
Deficit in transcription factor Tbx1 causes heart defects in humans and mice. Here the authors show that Tbx1 regulates gene expression by recruiting histone methyltransferases that affect chromatin marks, and that a drug inhibiting histone demethylation

NK4 antagonizes Tbx1/10 to promote cardiac versus pharyngeal muscle fate in the ascidian second heart field. [PDF]

PLoS Biology, 2013
The heart and head muscles share common developmental origins and genetic underpinnings in vertebrates, including humans. Parts of the heart and cranio-facial musculature derive from common mesodermal progenitors that express NKX2-5, ISL1, and TBX1. This

Tumor‐Derived Exosomal piR‐hsa‐28212 Promotes Lymphatic Metastasis in Breast Cancer

Cancer Science, EarlyView.
Breast cancer–derived exosomal piR‐hsa‐28212 promotes lymphangiogenesis and lymph node metastasis by activating VEGFC/VEGFR3 signaling. It stabilizes TBX1 mRNA in lymphatic endothelial cells and METTL3 protein in tumor cells, enhancing VEGFR3 expression and VEGFC secretion.

Ash2l interacts with Tbx1 and is required during early embryogenesis [PDF]

Experimental Biology and Medicine, 2010
TBX1 encodes a DNA binding transcription factor that is commonly deleted in human DiGeorge syndrome and plays an important role in heart development. Mechanisms of Tbx1 function, such as Tbx1 interacting regulatory proteins and transcriptional target specificity, are largely unknown.

A Practical Guide to Chromosome Microarray Interpretation for Paediatricians

Journal of Paediatrics and Child Health, EarlyView.
ABSTRACT Introduction Chromosome microarray (CMA) is a test commonly ordered by general paediatricians. It has diagnostic yield between 10%–15% in individuals with neurodevelopmental delay, autism and/or multiple congenital abnormalities. CMA identifies copy number variants (CNV) including deletions and duplications, which may be pathogenic, variants ...

Tbx1 Regulates Proliferation and Differentiation of Multipotent Heart Progenitors [PDF]

Circulation Research, 2009
Rationale : TBX1 encodes a T-box transcription factor implicated in DiGeorge syndrome, which affects the development of many organs, including the heart.
