Novel potential causative genes in carotid paragangliomas.

ABSTRACT:

Background

Carotid paragangliomas (CPGLs) are rare neuroendocrine tumors that arise from the paraganglion at the bifurcation of the carotid artery and are responsible for approximately 65% of all head and neck paragangliomas. CPGLs can occur sporadically or along with different hereditary tumor syndromes. Approximately 30 genes are known to be associated with CPGLs. However, the genetic basis behind the development of these tumors is not fully elucidated, and the molecular mechanisms underlying CPGL pathogenesis remain unclear.

Methods

Whole exome and transcriptome high-throughput sequencing of CPGLs was performed on an Illumina platform. Exome libraries were prepared using a Nextera Rapid Capture Exome Kit (Illumina) and were sequenced under 75 bp paired-end model. For cDNA library preparation, a TruSeq Stranded Total RNA Library Prep Kit with Ribo-Zero Gold (Illumina) was used; transcriptome sequencing was carried out with 100 bp paired-end read length. Obtained data were analyzed using xseq which estimates the influence of mutations on gene expression profiles allowing to identify potential causative genes.

Results

We identified a total of 16 candidate genes (MYH15, CSP1, MYH3, PTGES3L, CSGALNACT2, NMD3, IFI44, GMCL1, LSP1, PPFIBP2, RBL2, MAGED1, CNIH3, STRA6, SLC6A13, and ATM) whose variants potentially influence their expression (cis-effect). The strongest cis-effect of loss-of-function variants was found in MYH15, CSP1, and MYH3, and several likely pathogenic variants in these genes associated with CPGLs were predicted.

Conclusions

Using the xseq probabilistic model, three novel potential causative genes, namely MYH15, CSP1, and MYH3, were identified in carotid paragangliomas.

Project description:BackgroundKeloids are benign skin tumors that appears on skin lesions in humans. Keloids are characterized by invasive tumor growth and are highly prone to recurrence after treatment. The incidence of keloids is ethnically specific; however, the molecular mechanism underlying the incidence of keloids in the Chinese population remains unclear. To date, no reports appear to have been published on the molecular characteristics underlying keloids in the Chinese population from the perspective of whole-genome sequencing.MethodsIn this study, we collected keloid samples from 9 keloid patients underwent surgery in the Department of Dermatology, The First Affiliated Hospital of Soochow University, paired them to normal skin tissues, and performed whole-exome sequencing. The average depth of the samples was 1,200×, and the average exome coverage was 98.90%.ResultsThe bioinformatics analysis identified 3,125 single nucleotide variants (SNVs) and 299 insertions/deletions (InDels). The major mutation characteristics of the SNVs were C > A and C > T. The non-synonymous SNV types included stopgain, and stoploss. The non-synonym InDels included frameshift deletion, frameshift insertion, and stopgain. We also found a total of 67,873 copy number variations (CNVs) in the samples. The genes with the highest mutation frequency included mucin 4 (MUC4) (55.6%), tubulin tyrosine ligase like 12 (TTLL12) (33.3%), calcium voltage-gated channel subunit alpha1 (CACNA1C) (33.3%), and mucin 12 (MUC12) (33.3%). The average tumor mutation burden (TMB) was 289 mutations/million base pair (MB). The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis revealed that the mutated genes were mainly concentrated in micro ribonucleic acids in cancer and the calcium signaling pathway. The Gene Ontology (GO) analysis showed that mutant genes were mainly concentrated in binding cells, cell parts, and cellular processes.ConclusionsWhole-exome sequencing was performed in the Chinese keloid patients and some potential candidate genes related to keloid occurrence and development were identified, which may provide new molecular targets for the clinical diagnosis and treatment of keloid patients.

Project description:BackgroundImmune microenvironment is one of the essential characteristics of carotid atherosclerosis (CAS), which cannot be reversed by drug therapy alone. Thus, there is a pressing need to develop novel immunoregulatory strategies to delay this pathological process that drives cardiovascular-related diseases. This study aimed to detect changes in the immune microenvironment of vascular tissues at various stages of carotid atherosclerosis, as well as cluster and stratify vascular tissue samples based on the infiltration levels of immune cell subtypes to distinguish immune phenotypes and identify potential hub genes regulating the immune microenvironment of carotid atherosclerosis.Materials and methodsRNA sequencing datasets for CAS vascular tissue and healthy vascular tissue (GSE43292 and GSE28829) were downloaded from the Gene Expression Omnibus (GEO) database. To begin, the immune cell subtype infiltration level of all samples in both GSE43292 and GSE28829 cohorts was assessed using the ssGSEA algorithm. Following this, consensus clustering was performed to stratify CAS samples into different clusters. Finally, hub genes were identified using the maximum neighborhood component algorithm based on the construction of interaction networks, and their diagnostic efficiency was evaluated.ResultsCompared to the controls, a higher number of immune cell subtypes were enriched in CAS samples with higher immune scores in the GSE43292 cohort. Advanced CAS was characterized by high immune cell infiltration, whereas early CAS was characterized by low immune cell infiltration in the GSE28829 cohort. Moreover, CAS progression may be related to the immune response pathway. Biological processes associated with muscle cell development may impede the progression of CAS. Finally, the hub genes PTPRC, ACTN2, ACTC1, LDB3, MYOZ2, and TPM2 had satisfactory efficacy in the diagnosis and prediction of high and low immune cell infiltration in CAS and distinguishing between early and advanced CAS samples.ConclusionThe enrichment of immune cells in vascular tissues is a primary factor driving pathological changes in CAS. Additionally, CAS progression may be related to the immune response pathway. Biological processes linked to muscle cell development may delay the progression of CAS. PTPRC, ACTN2, ACTC1, LDB3, MYOZ2, and TPM2 may regulate the immune microenvironment of CAS and participate in the occurrence and progression of the disease.
