Insights

Cleft palate (CP) lacks early treatment. Blocking phosphatase and tensin homolog (Pten) may prevent CP by targeting glycolysis during embryonic development, offering a novel therapeutic approach.

Area of Science:

  • Developmental biology
  • Molecular biology
  • Biochemistry

Background:

  • Cleft palate (CP) results from abnormal embryonic development and currently lacks interceptive treatments.
  • Germline deletion of phosphatase and tensin homolog (Pten) is linked to embryonic malformations and influences glycolysis.
  • The specific roles of Pten in CP and its connection to glycolysis remain largely unexplored.

Purpose of the Study:

  • To investigate the role of Pten in cleft palate (CP) development.
  • To explore the relationship between CP, Pten, and glycolysis.
  • To assess the potential of Pten inhibition as an early interceptive treatment for CP.

Main Methods:

  • Development of in vitro and in vivo Pten knockdown models.
  • Utilizing Pten inhibitors, such as VO-OHpic, for experimental treatment.
  • Analysis of the interplay between Pten, glycolysis, and palate development.

Main Results:

  • Pten knockdown models were successfully constructed.
  • Preliminary evidence suggests Pten inhibition may reduce CP occurrence.
  • The study identified a crosstalk between Pten and glycolysis in palate development.

Conclusions:

  • Blocking Pten presents a potential early interceptive strategy for preventing cleft palate.
  • Intervention during early palate development, particularly when exposed to harmful environments, may be effective.
  • The findings highlight the crucial role of the Pten-glycolysis pathway in embryonic palate formation.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

What is Glycolysis?00:56

What is Glycolysis?

Overview
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Glycolysis: Preparatory Phase01:21

Glycolysis: Preparatory Phase

In cellular metabolism (the complete breakdown of glucose to extract energy),  glycolysis is the first step. Glycolysis takes place in the cytoplasm of both prokaryotic and eukaryotic cells. Glucose enters heterotrophic cells in two ways. One method is through secondary active transport, where the transport takes place against the glucose concentration gradient. The other mechanism uses a group of integral proteins called GLUT proteins, also known as glucose transporter proteins. These...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
