Laboratory of Bioinformatics and Biostatistics is dedicated to:
In the field of clinical bioinformatics, the laboratory, in cooperation with the Clinic of
Gynecology and Obstetrics and the Institute of Molecular Biology and Genomics, participated
in implementation of non-invasive prenatal screening (NIPS) at JFMED CU, and improvements of bioinformatics of NIPS.
In close cooperation with the Institute of Molecular Biology and Genomics JFMED CU, the laboratory takes part in oncological research projects involving NGS sequencing (DNAseq, RNAseq).
Under the supervision of the Institute of Pathological Anatomy of JFMED CU, the laboratory
participates in introducing the TSO 500 panel for genomic profiling of oncological samples. Biostatistical analyses are also used in research projects of other laboratories of BioMed, institutes of JFMED CU, and the clinics of Martin University Hospital. In addition to basic and advanced statistical methods, data analysis process also uses, if appropriate, machine
learning (ML) algorithms. Machine learning is also used for prioritization of biomarkers in omics studies.
The laboratory is equipped with an iCompute server and DELL servers. The laboratory caries out bioinformatic analyses using an in-house statistical pipeline which were developed with the assistance of the BioConductor libraries and R, as well as other bioinformatic tools. In cooperation with the Institute of Molecular Biology and Genomics, the laboratory also applies the Qiagen CLC Workbench for NGS analyses. The R software tool is used for biostatistical analyses and machine learning.
