Several types of non-coding RNAs such as circRNAs, lncRNAs, and miRNAs have been identified to regulate mRNAs through the mechanism known as the competitive endogenous RNA (ceRNA) network. To explore the role of the ceRNA regulatory network in the immune microenvironment of bladder cancer, whole-transcriptome sequencing of bladder tumor and its peritumoral tissues from 38 bladder cancer patients, with a total of 63 samples, was performed to screen differentially expressed circ-, lnc-, mi-, and mRNAs to construct a circ/lnc-mi-mRNA regulatory network with pruning algorithms. We excavated a key immune-related gene to build the final ceRNA network as hsa-miR-107 sponged by hsa-circ-000211, AC108488.

He complained of dysuria and recurrent urinary retention and was initially diagnosed with benign prostatic hyperplasia. Accidentally, a dark-brown pigmented macula was found in the distal urethra at the end of transurethral prostatectomy when we exited the resectoscope, transurethral resection of the nidus and sent to pathological examination showed the characteristics of melanoma.

While large-scale sequencing projects have provided a preliminary understanding of tumour heterogeneity, these findings are based on the average signals obtained from the pooled populations of diverse cells. Recent advances in single-cell sequencing (SCS) technologies have been critical in this regard, opening up new ways of understanding the nuanced tumour biology by identifying distinct cellular subpopulations, dissecting the tumour microenvironment, and characterizing cellular genomic mutations.

Drug resistance is the main reason for chemotherapeutic failure in gastric cancer. Wiskott-Aldrich syndrome protein family member 3 (WASF3) is required for invasion and metastasis of different cancers.

The coexpression of and in gastric cancer patients and cells were evaluated. was overexpressed and the expression of was decreased in gastric cancer tissues compared with normal tissues (p < 0.
View Article and Find Full Text PDFLynch syndrome (LS) is a common cancer syndrome that is inherited in an autosomal dominant manner. Its pathogenesis is thought to be closely related to germline mutations of mismatch repair (MMR) genes such as the MLH1, MSH2, PMS2 and MSH6 genes. This study identifies a Chinese family with LS clinically diagnosed according to the Amsterdam II criteria.
