Insights

Low expression of DRAIC, a long non-coding RNA, correlates with poor survival in lung cancer. The DRAIC-SH3 domain-binding kinase 1 (SBK1) axis may offer new diagnostic and therapeutic strategies for lung adenocarcinoma and lung squamous cell carcinoma.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genomics

Background:

  • Long non-coding RNAs (lncRNAs) are critical regulators in cancer development and progression.
  • DRAIC, a known migration inhibitor, is implicated in lung adenocarcinoma progression, but its underlying mechanisms require elucidation.
  • Understanding lncRNA roles is crucial for advancing cancer research and treatment.

Purpose of the Study:

  • To investigate the role of DRAIC in lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC) using bioinformatics analysis.
  • To explore the molecular mechanisms through which DRAIC influences cancer progression.
  • To identify potential diagnostic and therapeutic targets based on the DRAIC-mediated pathway.

Main Methods:

  • Utilized multiple bioinformatics tools to analyze gene expression data.
  • Examined the correlation between DRAIC expression levels and patient survival outcomes.
  • Investigated the regulatory network involving DRAIC, microRNAs, and target genes, specifically SH3 domain-binding kinase 1 (SBK1).

Main Results:

  • Patients with lower DRAIC expression exhibited significantly poorer overall survival in both LUAD and LUSC.
  • SH3 domain-binding kinase 1 (SBK1) mRNA levels were found to be downregulated in patients with low DRAIC expression.
  • Mechanistic insights suggest DRAIC acts as a competing endogenous RNA (ceRNA), potentially by sponging miRNA-92a, thereby regulating SBK1 expression.

Conclusions:

  • The DRAIC-SBK1 axis is consistently dysregulated in LUAD and LUSC, indicating a tumor-suppressive role for DRAIC.
  • This axis represents a promising target for developing novel diagnostic biomarkers and therapeutic strategies for lung cancers.
  • Further research into the DRAIC-SBK1 pathway could lead to improved patient outcomes.

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...

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...

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,...

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 Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

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...
