Summary
This study identified key genetic alterations in papillary thyroid carcinoma (PTC) in Chinese patients using next-generation sequencing. Findings reveal novel driver genes and pathways, offering potential biomarkers for PTC diagnosis and treatment.
Area of Science:
- Oncology
- Genetics
- Molecular Biology
Background:
- Papillary thyroid carcinoma (PTC) is a prevalent endocrine malignancy.
- Understanding the genetic landscape of PTC in diverse populations, such as Chinese patients, is crucial for targeted therapies.
Purpose of the Study:
- To comprehensively characterize somatic genomic and transcriptomic alterations in Chinese PTC patients.
- To identify novel driver genes, pathways, and structural variants associated with PTC development.
Main Methods:
- Next-generation sequencing (NGS) including whole genome sequencing (WGS), whole exome sequencing (WES), and RNA-sequencing (RNA-seq).
- Analysis of tumor-normal DNA and RNA pairs from 16 Chinese PTC patients.
- Identification of somatic mutations, copy number aberrations, and gene fusions.
Main Results:
- Identified significant PTC driver genes (e.g., COL11A1, TP53, PLXNA4) and pathways (metabolic, cancer, olfactory, calcium signaling).
- Discovered genes with copy number aberrations and expression changes (e.g., BRD9, TRIP13).
- Characterized novel structural variants and fusion proteins (e.g., TRNAU1AP-RCC1).
Conclusions:
- This research provides a valuable list of novel candidate genes with somatic alterations in PTC from Chinese patients.
- These findings may serve as potential biomarkers for PTC and guide future mechanistic studies and therapeutic strategies.

01:12Loss of Tumor Suppressor Gene Functions
5.8K
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.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

02:21Cancers Originate from Somatic Mutations in a Single Cell
14.4K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

02:23Abnormal Proliferation
5.0K
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...

9.3K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

10.1K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...
