The aim of the present study was to screen potential key genes associated with osteoporosis in laying hens. We performed association analysis of single nucleotide polymorphisms of selected genes encoding non-collagenous proteins (IBSP, SPP1, FN1, MEPE, DCN, THBS2) with parameters of bones in a group of ISA Brown laying hens. The surveyed parameters were bone breaking strength, length, width and bone mass. In this pilot study, nineteen samples for genes encoding non-collagenous proteins were tested. The polymorphisms were detected using PCR method and sequencing. Seven polymorphisms have been discovered in genes encoding noncollagenous proteins in the genes FN1 (c.7413A>G, c.7440+57G>A, c.7440+105G>A, c.7441-71T>C), DCN (c.158C>T) and SPP1 (c.362+117G>C, c.363-88G>C), of which two of these polymorphisms were synonymous and five were in the intron. Despite the position of the found polymorphisms, no association with the mechanical parameters of the bones were found.

In order to identify potential diagnostic and prognostic biomarkers, and treatment targets for head and neck squamous cell carcinoma (HNSCC), the present study obtained the gene expression profiles in HNSCC through public data mining, and core genes were identified using a series of bioinformatics analysis methods and databases. A total of nine hub genes (SPP1, ITGA6, TMPRSS11D, MMP1, LAMC2, FAT1, ACTA1, SERPINE1 and CEACAM1) were identified to be significantly correlated with HNSCC. Furthermore, overall survival analysis demonstrated that the expression values of hub genes were associated with overall survival in HNSCC. Furthermore, certain of the identified genes, including, TMPRSS11D, ACTA1 and CEACAM1, have not been thoroughly investigated in HNSCC previously. Taken together, the nine hub genes obtained by screening in the present study may serve as potential tumor markers and important prognostic indicators for HNSCC.
