Summary
This summary is machine-generated.High CD47 expression is linked to poor cancer survival, but this study reveals IFT57 may be a better predictor. Coexpression of CD47 and IFT57 correlates with improved survival in certain cancers.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- High CD47 expression on cancer cells typically inhibits phagocytosis, correlating with poor patient survival.
- However, CD47 mRNA levels show variable correlations with survival across different cancer types.
- IFT57, a primary cilium component, is co-linear with CD47, suggesting potential coregulation.
Purpose Of The Study
- To investigate the relationship between CD47 and IFT57 gene expression in human cancers.
- To determine whether CD47 or IFT57 expression better predicts patient survival.
- To identify downstream targets of IFT57 in cancer pathogenesis.
Main Methods
- Analysis of The Cancer Genome Atlas (TCGA) datasets for CD47 and IFT57 coexpression.
- Correlation analysis of gene expression with patient survival data.
- Transcriptome analysis following CD47 or IFT57 knockdown in thyroid carcinoma cell lines.
Main Results
- IFT57 was identified as a top coexpressed gene with CD47 across numerous cancer types.
- Coexpression of CD47 and IFT57 correlated with improved survival in papillary thyroid carcinomas.
- CRACD was identified as a downstream target of IFT57, and its expression inversely correlated with IFT57 and survival in several cancers.
Conclusions
- IFT57, rather than CD47, may be the primary regulator of patient survival in certain cancers like thyroid carcinoma, lung adenocarcinoma, and glioma.
- The findings suggest a novel role for IFT57 and its downstream targets in cancer progression and prognosis.

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.

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...
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...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...
