Epigenetic therapies of osteoporosis.

The study of epigenetics reaches its 50th anniversary, however, its clinical application is gradually coming into the clinical setting. Osteoporosis is one of the major and widely diffused bone diseases. Pathogenic mechanisms at the epigenetic level may interfere with bone remodeling occurring during osteoporosis.

Patient-derived organoids as a potential model to predict response to PD-1/PD-L1 checkpoint inhibitors.

Selection of cancer patients for treatment with immune checkpoint inhibitors remains a challenge due to tumour heterogeneity and variable biomarker detection. PD-L1 expression in 24 surgical chordoma specimen was determined immunohistochemically with antibodies 28-8 and E1L3N. The ability of patient-derived organoids to detect treatment effects of nivolumab was explored by quantitative and qualitative immunofluorescence and FACS analysis.

Sarcoma Spheroids and Organoids-Promising Tools in the Era of Personalized Medicine.

Cancer treatment is rapidly evolving toward personalized medicine, which takes into account the individual molecular and genetic variability of tumors. Sophisticated new in vitro disease models, such as three-dimensional cell cultures, may provide a tool for genetic, epigenetic, biomedical, and pharmacological research, and help determine the most promising individual treatment. Sarcomas, malignant neoplasms originating from mesenchymal cells, may have a multitude of genomic aberrations that give rise to more than 70 different histopathological subtypes.

Segmental vs non-segmental thoracic pedicle screws constructs in adolescent idiopathic scoliosis: is there any implant alloy effect?

Purpose: The aim of this study is to understand how many anchor sites are necessary to obtain maximum posterior correction of idiopathic scoliotic curve and if the alloy of instrumentation, stainless steel or titanium, may have a role in the percent of scoliosis correction.

Methods: We reviewed 143 consecutive patients, affected by AIS (Lenke 1-2), who underwent a posterior spinal fusion with pedicle screw-only instrumentation between 2002 and 2005. According to the implant density and alloy used we divided the cohort in four groups.

Clinical and microbiological outcomes in haematogenous spondylodiscitis treated conservatively.

Introduction: Spondylodiscitis refers to infections of the intervertebral disc and the adjacent vertebral body. Although it is still considered a rare condition, its rate is projected to increase. Mortality rate is considered to be low, but an estimated one third of the survivors experience residual disabilities.

Yin Yang I as an Epimodulator of miRNAs in the Metastatic Cascade.

Yin Yang 1 (YY1) belongs to the polycomb group (PcG) of proteins that modify chromatin epigenetically during dynamic regulation of their target genes. The predominant feature of YY1 is the zinc finger, an ancient structural motif that mediates protein-protein interactions and is capable of interacting with both DNA and RNA. Evidence reveals that YY1 acts predominantly as an epigenetic modulator, influencing the activity and/or localization of epigenetic modifiers molecules such as DNA methylation transferases, histone deacetylases, or non-coding RNAs.
