Abstract

Insights

Transcriptional enhanced associate domain factor 1 (TEAD1) compensates for cortactin-binding protein 2 N-terminal-like (CTTNBP2NL) deficiency in papillary thyroid carcinoma (PTC). TEAD1 promotes PTC cell survival and growth, indicating its potential as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Papillary thyroid carcinoma (PTC) molecular mechanisms require elucidation for drug target identification.
  • Transcriptional enhanced associate domain factor 1 (TEAD1) and cortactin-binding protein 2 N-terminal-like (CTTNBP2NL) roles in PTC are not fully understood.

Purpose of the Study:

  • To investigate the molecular interactions between TEAD1 and CTTNBP2NL in PTC cells.
  • To assess the impact of these interactions on PTC cell proliferation, apoptosis, and clonogenicity.

Main Methods:

  • Differential gene expression analysis of TEAD1 and CTTNBP2NL in PTC tissues.
  • Correlation analysis of gene expression with patient survival.
  • In vitro experiments using TPC1 cells with manipulated TEAD1 and CTTNBP2NL levels.
  • Molecular biochemistry, cell proliferation, and colony formation assays.

Main Results:

  • TEAD1 and CTTNBP2NL expression levels significantly correlated with overall patient survival in PTC.
  • TEAD1 overexpression mitigated CTTNBP2NL downregulation effects, reducing proliferation and increasing apoptosis in TPC1 cells.
  • TEAD1 promoted cell proliferation and colony formation, while CTTNBP2NL silencing diminished cell growth.

Conclusions:

  • TEAD1 plays a compensatory role in PTC by alleviating CTTNBP2NL deficiency, promoting cell survival and growth.
  • TEAD1 represents a potential therapeutic target for papillary thyroid carcinoma.

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Co-activators and Co-repressors02:04

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Transcription Factors02:16

Transcription Factors

Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...

Eukaryotic Transcription Activators02:42

Eukaryotic Transcription Activators

Transcription activators are proteins that promote the transcription of genes from DNA to RNA. In most cases, these proteins contain two separate domains ‒ a domain that binds to DNA and a domain for activating transcription; however, in some cases, a single domain is responsible for both binding and activation of transcription, as seen in the glucocorticoid receptor and MyoD.
The binding domains are capable of recognizing and interacting with regulatory sequences on the DNA. These...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
