Abstract

Insights

Increased expression of RIPK3, a necroptosis marker, was observed in pterygium tissues. Higher RIPK3 levels in pterygium may offer protection against recurrence, suggesting a role in disease pathogenesis.

Area of Science:

  • Ophthalmology
  • Cell Biology
  • Molecular Biology

Background:

  • Pterygium is a common ocular surface disease involving fibrovascular growth on the cornea.
  • Cell death pathways, including necroptosis, are implicated in regulating cell cycle dynamics.
  • The role of necroptosis in pterygium pathogenesis remains unclear.

Purpose of the Study:

  • To investigate the expression levels of necroptosis markers, specifically RIPK3 and RIPK1, in pterygium tissues.
  • To determine the potential role of necroptosis in the development and progression of pterygium.

Main Methods:

  • Quantitative real-time PCR was used to measure RIPK3 and RIPK1 mRNA levels.
  • Pterygium tissue samples from 41 patients were compared with normal conjunctival tissues.
  • Expression patterns of RIPK3 and RIPK1 were analyzed in relation to pterygium.

Main Results:

  • Significantly elevated RIPK3 mRNA expression was found in pterygium tissues compared to controls.
  • No significant changes in RIPK1 mRNA levels were observed between pterygium and control tissues.
  • Increased RIPK3 expression showed a negative correlation with pterygium recurrence rates.

Conclusions:

  • The findings suggest that RIPK3 may play a protective role in preventing pterygium recurrence.
  • Necroptosis, mediated by RIPK3, could be a key factor in the pathogenesis of pterygium.
  • RIPK3 warrants further investigation as a potential therapeutic target for pterygium.

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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

piRNA - Piwi-interacting RNAs

PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
