Innovative Biomarkers for Obesity and Type 1 Diabetes Based on Bifidobacterium and Metabolomic Profiling

Stephan Morgenthaler, Paul Refinetti, Mariya Yuryevna Skvortsova

The role of Bifidobacterium species and microbial metabolites such as short-chain fatty acids (SCFAs) and human milk oligosaccharides in controlling intestinal inflammation and the pathogenesis of obesity and type 1 diabetes (T1D) has been largely studied ...

Somatic Mitochondrial DNA Point Mutations Used as Biomarkers to Demonstrate Genomic Heterogeneity in Primary Prostate Cancer

Paul Refinetti, Per Olaf Ekstrom

Primary prostate tumor heterogeneity is poorly understood, leaving research efforts with challenges regarding the initiation and advancement of the disease. The growth of tumor cells is accompanied by mutations in nuclear and in mitochondrial genomes. Thus ...

Is detection of intraperitoneal exfoliated tumor cells after surgical resection of rectal cancer a prognostic factor of survival?

Paul Refinetti, Per Olaf Ekstrom

Background: The prognostic significance of free cancer cells detected in peritoneal fluid at the time of rectal surgery remains unclear. A substantial number of patients will develop metastatic disease even with successful local treatment. This prospective ...

Extraction of cell-free DNA from urine, using polylysine-coated silica particles

Paul Refinetti, Sho Takano

DNA analysis is used for a variety of purposes, including disease diagnosis and DNA profiling; this involves extracting DNA from living organisms. In this study, we prepared polycationic silica particles to extract DNA that has the negatively charged phosp ...

Mapping mitochondrial heteroplasmy in a Leydig tumor by laser capture microdissection and cycling temperature capillary electrophoresis

Stephan Morgenthaler, Paul Refinetti, Per Olaf Ekstrom

Background: The growth of tumor cells is accompanied by mutations in nuclear and mitochondrial genomes creating marked genetic heterogeneity. Tumors also contain non-tumor cells of various origins. An observed somatic mitochondrial mutation would have occu ...

Cell lineage tracing in human tissues using somatic mitochondrial mutations

Paul Refinetti

Lineage tracing is a basic concept in developmental biology, as well as diseases related to organ development. A reliable method to track cell lineages in human tissues has the potential to greatly contribute to the fields of oncogenesis, tissue renewal, a ...

Cycling temperature capillary electrophoresis: A quantitative, fast and inexpensive method to detect mutations in mixed populations of human mitochondrial DNA

Stephan Morgenthaler, Paul Refinetti, Per Olaf Ekstrom

Cycling temperature capillary electrophoresis has been optimised for mutation detection in 76% of the mitochondrial genome. The method was tested on a mixed sample and compared to mutation detection by next generation sequencing. Out of 152 fragments 90 we ...
