Abstract

Insights

Aurora kinase A (AURKA) is overexpressed in non-small cell lung cancer (NSCLC) tumors, particularly in poorly differentiated and specific subtypes. This finding highlights AURKA as a potential biomarker for certain NSCLC classifications.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Cycle Regulation

Background:

  • Aurora kinase A (AURKA) is a serine/threonine kinase crucial for cell cycle progression and chromosomal segregation.
  • AURKA overexpression is linked to neoplastic transformation and chromosomal instability in various cancers.
  • Deregulated Aurora Kinase expression contributes to cancer progression.

Purpose of the Study:

  • To investigate AURKA gene and protein expression in non-small cell lung cancer (NSCLC) specimens.
  • To correlate AURKA expression levels with clinico-pathological features of NSCLC patients.

Main Methods:

  • Quantitative real-time PCR and immunohistochemistry were employed.
  • Analysis was performed on matched tumor and normal lung tissues from NSCLC patients.

Main Results:

  • AURKA expression was significantly elevated in NSCLC tumor tissues compared to normal lung tissue (p<0.01).
  • Elevated AURKA expression was observed in moderately and poorly differentiated NSCLC subtypes (p<0.01).
  • AURKA was also upregulated in squamous cell carcinomas and adenocarcinomas compared to bronchioloalveolar histotype (p=0.029).

Conclusions:

  • AURKA overexpression in NSCLC is associated with specific tumor subtypes and poor differentiation.
  • The findings suggest AURKA's role in the progression of certain NSCLC types.

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 rapamycin-insensitive companion...

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...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA (lncRNA)...
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 daughter...
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...
