Summary

This summary is machine-generated.

Long non-coding RNA ROR (Linc-ROR) is elevated in thyroid cancer patients and linked to poorer outcomes. Silencing Linc-ROR inhibits tumor growth and immune evasion, suggesting it as a therapeutic target.

Area Of Science

  • Endocrinology
  • Oncology
  • Molecular Biology

Background

  • Thyroid cancer is the leading endocrine malignancy.
  • Long non-coding RNAs (LncRNAs) play critical roles in cancer progression.
  • LncRNA ROR (Linc-ROR) has demonstrated tumor-regulatory functions in various cancers.

Purpose Of The Study

  • To investigate the role and mechanism of Linc-ROR in thyroid cancer.
  • To determine the association between Linc-ROR levels and clinicopathological features.
  • To explore Linc-ROR's impact on tumor growth, immune escape, and macrophage polarization.

Main Methods

  • Quantification of Linc-ROR levels in 70 thyroid cancer patients.
  • Assessment of cell viability using CCK-8 assays.
  • Xenograft tumor models for evaluating tumor growth.
  • Flow cytometry for CD8+ T cell analysis.
  • ELISA assays for cytokine detection (IL-10, IFN-γ, TNF-β).

Main Results

  • Linc-ROR levels were significantly elevated in thyroid cancer patients.
  • Higher Linc-ROR expression correlated with poor survival, lymph node metastasis, and advanced TNM stage.
  • Linc-ROR silencing suppressed thyroid cancer cell proliferation and tumor growth.
  • Silenced Linc-ROR reduced immune escape and M2 macrophage polarization.
  • The PI3K/AKT signaling pathway mediated Linc-ROR's effects.

Conclusions

  • Linc-ROR is upregulated in thyroid cancer and associated with adverse prognostic factors.
  • Linc-ROR inhibition hinders tumor progression and modulates the tumor immune microenvironment.
  • Linc-ROR, potentially via PI3K/AKT signaling, represents a promising therapeutic target for thyroid cancer.

mTOR Signaling and Cancer Progression 03:03

3.7K

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.

8.4K

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...

PI3K/mTOR/AKT Signaling Pathway 01:22

3.3K

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...

Abnormal Proliferation 02:23

4.4K

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 <em>Ras</em> Gene 02:38

6.1K

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.
Ras is a...

Experimental RNAi 02:15

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
