Abstract

Insights

High ETS1 expression correlates with clear cell renal cell carcinoma (ccRCC) progression. Targeting ETS1 and ERK may inhibit ccRCC cell proliferation, migration, and invasion, suggesting ETS1 as a therapeutic target.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Research

Background:

  • ETS1 expression is elevated in clear cell renal cell carcinoma (ccRCC) tissues.
  • The precise role of ETS1 in ccRCC pathogenesis remains unclear.

Purpose of the Study:

  • To investigate the association between ETS1 expression and ccRCC progression.
  • To elucidate the functional role of ETS1 in ccRCC cell proliferation, migration, and invasion.

Main Methods:

  • Protein-protein interaction network analysis using STRING.
  • Cell viability, proliferation, migration, and invasion assays (CCK-8, clonogenic, wound-healing, Transwell).
  • Western blot analysis for protein expression; PERK and ERK pathway inhibitors were utilized.

Main Results:

  • Significantly increased ETS1 expression in ccRCC tissues and its correlation with advanced tumor stage, lymph node metastasis, and higher grades (p<0.05).
  • ETS1 knockdown and PERK inhibition suppressed ccRCC cell proliferation, migration, and invasion.
  • ETS1 knockdown reduced MMP-2 expression; ERK inhibition affected both ETS1 and MMP-2 expression.

Conclusions:

  • Elevated ETS1 expression is linked to ccRCC progression.
  • ETS1 promotes ccRCC proliferation via MMP2 upregulation.
  • Combined ETS1 knockdown and ERK inhibition show therapeutic potential for ccRCC.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

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.

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...

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...

Role of Matrix Metalloproteases in Degradation of ECM01:23

Role of Matrix Metalloproteases in Degradation of ECM

Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
