Insights

RNA methyltransferase METTL16 is highly expressed in thyroid cancer, driving tumor progression and impacting patient prognosis. This study identifies SAMD11 as a key target gene, offering new insights into thyroid cancer molecular mechanisms.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Thyroid cancer research has advanced, but molecular mechanisms require further exploration.
  • Understanding the role of RNA methyltransferases in cancer is crucial.

Purpose of the Study:

  • To investigate the role and molecular mechanisms of RNA methyltransferase METTL16 in thyroid cancer development and progression.
  • To identify potential therapeutic targets within METTL16-regulated pathways.

Main Methods:

  • Bioinformatic analysis of tumor databases and public datasets.
  • Immunofluorescence on clinical tissue microarrays.
  • In vitro and in vivo experiments assessing cell proliferation, migration, and invasion.
  • Identification and validation of METTL16 target genes.

Main Results:

  • METTL16 is highly expressed in thyroid cancer tissues and cells, correlating with poor patient prognosis.
  • METTL16 significantly regulates thyroid cancer cell proliferation, migration, and invasion.
  • SAMD11 was identified as a direct target gene of METTL16, playing a role in thyroid cancer progression.

Conclusions:

  • METTL16 is a key oncogenic factor in thyroid cancer progression.
  • Targeting METTL16 and its downstream pathways, like SAMD11, may offer novel therapeutic strategies for thyroid cancer.

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...

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...

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...

Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
