CRISPR-Cas9 Targeted Enrichment and Next-Generation Sequencing for Mutation Detection.

Despite the rapid application of next-generation sequencing (NGS) technologies, target sequencing in regions of the genome is often required to diagnose many genetic diseases. Target enrichment can be an effective factor in reducing the cost of sequencing and the duration of sequencing. Recently, several clustered system regularly interspaced short palindromic repeats (CRISPR)-based methods (amplification-free sequencing) have been developed to target enrichment in combination with one of the NGS platforms.

Preclinical and Clinical Aspects of using Tazemetostate in Human Cancers.

Epigenetic drugs are novel drug categories with promising effects in different cancers. Tazemetostate is among the drugs that were recently used in clinical settings, especially in the treatment of specific tumors and lymphomas. There are a growing number of ongoing clinical trials evaluating the safety and efficacy of tazemetostate in different cancers.

Circulating miR-455-3p, miR-5787, and miR-548a-3p as potential noninvasive biomarkers in the diagnosis of acute graft-versus-host disease: a validation study.

Currently, acute graft-versus-host disease (aGVHD) diagnosis is based on clinical features and pathological findings. Until now, there is no non-invasive diagnostic test for aGVHD. MicroRNAs may act as promising predictive, diagnostic, or prognostic biomarkers for aGVHD.

CRISPR-based biosensing systems: a way to rapidly diagnose COVID-19.

The outbreak of the emerging SARS-CoV-2 virus has highlighted the challenges of detecting viral infections, especially in resource-limited settings. The SARS-CoV-2 virus transmission chain is interrupted when screening and diagnosis can be performed on a large scale by identifying asymptomatic or moderately symptomatic patients. Diagnosis of COVID-19 with reverse transcription polymerase chain reaction (RT-PCR) has been limited due to inadequate access to complex, expensive equipment and reagents, which has impeded efforts to reduce the spread of virus transmission.

Molecular Genetics of Cleidocranial Dysplasia.

Cleidocranial dysplasia (CCD) is a genetic disorder with an autosomal dominant inheritance pattern. CCD characterized by abnormal clavicles, patent sutures and fontenelles, supernumerary teeth and short stature. Approximately 60-70% of CCD patients have mutations in the RUNX2 gene.

MicroRNAs as Potential Diagnostic, Prognostic, and Predictive Biomarkers for Acute Graft-versus-Host Disease.

Successful treatment of various hematologic diseases with allogeneic hematopoietic stem cell transplantation is often limited due to the occurrence of acute graft-versus-host disease (aGVHD). So far, there are no approved molecular biomarkers for the diagnosis and prediction of aGVHD at the clinical level due to our incomplete understanding of the molecular biology of the disease. Various studies have been conducted on animal models and humans to investigate the role of microRNAs in aGVHD pathogenesis to implicate them as biomarkers and therapeutic targets.
