Family with sequence similarity 83 (FAM83) is a newly identified family of oncogenes whose members play important roles in signaling and cancer progression. However, a thorough understanding of the FAM83 family in tumors is still lacking. Here, we performed a comprehensive analysis of the expression levels of the FAM83 family across cancers and patient prognoses using bioinformatics methods. We found that the expression levels of FAM83 family genes were upregulated in most tumors, and importantly, high expression levels of FAM83 family genes were related to poor prognosis in most tumors. In addition, we analyzed the relationship of FAM83 family genes with immune subtypes and the tumor microenvironment (TME). The results showed that FAM83 family genes were significantly associated with immune infiltrative subtypes and to varying degrees with the level of stromal cell infiltration and tumor stem cells. Finally, our study also showed the relationship between FAM83 family genes and drug sensitivity. Therefore, this pan-cancer analysis demonstrates the critical role of FAM83 family genes in tumor development and provides new clues for therapeutic strategies for cancer.

It was demonstrated that parental gene expression of maize in hybrid genetic background was different from that in their inbred lines. RT-PCR revealed a cDNA overexpressed in hybrid maize. The cDNA was reamplified and used to screen a corresponding cDNA library. A full length of a cDNA insert ZH01 was isolated and shown to have an open reading frame encoding 414a. a. Sequence comparison shows that ZH01 has extremely high similarity with the previously reported plant initiator factor elF-4A and distinct difference from another maize elF-4A gene MIF4A. Ovcrexpression of ZH01 in hybrid may involve vigorous growth of hybrid maize seedlings.
