[PERSONALIZED MEDICINE IN ONCOLOGY REQUIRES TEAMWORK BETWEEN MEDICAL ONCOLOGISTS AND MOLECULAR PATHOLOGISTS].

The systemic anti-cancer approach is based on medical/pharmaceutical interventions affecting cancer cells at multiple sites, including local and distant regions. Interventions include: cytotoxic chemotherapy agents used for direct extermination of proliferating cells, hormonal interventions altering the tumor environment and affecting its ability to survive and thrive, biological drugs restoring the function defective proteins in mutated tumors, and immunological medications encouraging effective immune recognition of tumor cells and associated immune response. "Personalized medicine in oncology" aims to make anti-cancer treatment more effective and with less side effects.

Methylome and transcriptome profiling in Myasthenia Gravis monozygotic twins.

Objective: To identify novel genetic and epigenetic factors associated with Myasthenia gravis (MG) using an identical twins experimental study design.

Methods: The transcriptome and methylome of peripheral monocytes were compared between monozygotic (MZ) twins discordant and concordant for MG, as well as with MG singletons and healthy controls, all females. Sets of differentially expressed genes and differentially methylated CpGs were validated using RT-PCR for expression and target bisulfite sequencing for methylation on additional samples.

Integrative analysis of methylome and transcriptome in human blood identifies extensive sex- and immune cell-specific differentially methylated regions.

The relationship between DNA methylation and gene expression is complex and elusive. To further elucidate these relations, we performed an integrative analysis of the methylome and transcriptome of 4 circulating immune cell subsets (B cells, monocytes, CD4(+), and CD8(+) T cells) from healthy females. Additionally, in light of the known sex bias in the prevalence of several immune-mediated diseases, the female datasets were compared with similar public available male data sets.

Brain region-specific methylation in the promoter of the murine oxytocin receptor gene is involved in its expression regulation.

Oxytocin is a nine amino acid neuropeptide that is known to play a critical role in fetal expulsion and breast-feeding, and has been recently implicated in mammalian social behavior. The actions of both central and peripheral oxytocin are mediated through the oxytocin receptor (Oxtr), which is encoded by a single gene. In contrast to the highly conserved expression of oxytocin in specific hypothalamic nuclei, the expression of its receptor in the brain is highly diverse among different mammalian species or even within individuals of the same species.

DNA methylation of specific CpG sites in the promoter region regulates the transcription of the mouse oxytocin receptor.

Oxytocin is a peptide hormone, well known for its role in labor and suckling, and most recently for its involvement in mammalian social behavior. All central and peripheral actions of oxytocin are mediated through the oxytocin receptor, which is the product of a single gene. Transcription of the oxytocin receptor is subject to regulation by gonadal steroid hormones, and is profoundly elevated in the uterus and mammary glands during parturition.
