Stem Cell Mobilization Performed with Different Doses of Cytarabine in Plasma Cell Myeloma Patients Relapsing after Previous Autologous Hematopoietic Cell Transplantation-A Multicenter Report by the Polish Myeloma Study Group.

Salvage autologous hematopoietic cell transplantation (auto-HCT) may be used to treat relapse of plasma cell myeloma occurring after previous auto-HCT. When an insufficient number of hematopoietic stem cells have been stored from the initial harvest, remobilization is necessary. Here, we aimed to analyze the efficacy and safety of different doses of cytarabine (total 800 vs.

Single-cell discovery of mA RNA modifications in the hippocampus.

-Methyladenosine (mA) is a prevalent and highly regulated RNA modification essential for RNA metabolism and normal brain function. It is particularly important in the hippocampus, where mA is implicated in neurogenesis and learning. Although extensively studied, its presence in specific cell types remains poorly understood.

Deterministic nuclear reprogramming of mammalian nuclei to a totipotency-like state by Amphibian meiotic oocytes for stem cell therapy in humans.

The ultimate aim of nuclear reprogramming is to provide stem cells or differentiated cells from unrelated cell types as a cell source for regenerative medicine. A popular route towards this is transcription factor induction, and an alternative way is an original procedure of transplanting a single somatic cell nucleus to an unfertilized egg. A third route is to transplant hundreds of cell nuclei into the germinal vesicle (GV) of a non-dividing Amphibian meiotic oocyte, which leads to the activation of silent genes in 24 h and robustly induces a totipotency-like state in almost all transplanted cells.

m A promotes planarian regeneration.

Regeneration is the regrowth of damaged tissues or organs, a vital process in response to damages from primitive organisms to higher mammals. Planarian possesses active whole-body regenerative capability owing to its vast reservoir of adult stem cells, neoblasts, providing an ideal model to delineate the underlying mechanisms for regeneration. RNA N -methyladenosine (m A) modification participates in many biological processes, including stem cell self-renewal and differentiation, in particular the regeneration of haematopoietic stem cells and axons.

Phase separation of Ddx3xb helicase regulates maternal-to-zygotic transition in zebrafish.

Vertebrate embryogenesis involves a conserved and fundamental process, called the maternal-to-zygotic transition (MZT), which marks the switch from a maternal factors-dominated state to a zygotic factors-driven state. Yet the precise mechanism underlying MZT remains largely unknown. Here we report that the RNA helicase Ddx3xb in zebrafish undergoes liquid-liquid phase separation (LLPS) via its N-terminal intrinsically disordered region (IDR), and an increase in ATP content promotes the condensation of Ddx3xb during MZT.

RAEB II type of myelodysplastic syndrome associated with axillary abscesses - Case Report.

Myelodysplastic syndromes (MDS) are clonal haematopoetic stem cells disorders, characterized by bone marrow dysplasia, ineffecitive haematopoesis and cytopenias. Due to neutropenia, infections are common. A case is presented of a patient with high-risk myelodysplastic syndrome (MDS) complicated by hidradenitis suppurativa that developed in both axillae.

Citrobacter freundii and Acinetobacter baumanii infection in a patient with neoplastic lung disease - Case report.

An 85-year-old male with a tumour in his right lung was admitted to Internal Diseases Ward to continue treatment after suffering a sudden cardiac arrest. An empiric antibiotic therapy with amoxycillin was introduced due to increased inflammation markers. Blood and sputum were collected.

Therapeutic Potential of Innate Lymphoid Cells for Multiple Myeloma Therapy.

Innate lymphoid cells (ILCs) are a recently identified family of lymphocyte-like cells lacking a specific antigen receptor. They are part of the innate immune system. They play a key role in tissue homeostasis and also control inflammatory and neoplastic processes.

An epileptic seizure and haemorrhage into the ventricular system of the brain as the first manifestations of acquired haemophilia A - Case report.

Acquired haemophilia (AH) is a suddenly occurring severe blood diathesis that affects both males and females and is caused by autoantibodies which inhibit coagulation factor VIII. The report describes an unusual case of acquired haemophilia in which an epileptic seizure and haemorrhage into the ventricular system of the brain were the first manifestations of the disease. In addition, APTT was prolonged to 94.

Salvage autologous hematopoietic stem cell transplantation for multiple myeloma performed with stem cells procured after previous high dose therapy - a multicenter report by the Polish Myeloma Study Group.

Salvage autologous hematopoietic stem cell transplantation (auto-HSCT) constitutes a therapeutic option for a group of well-selected patients with relapsed multiple myeloma (MM). However, if an insufficient number of stem cells were harvested and stored before the first auto-HSCT, stem cells need to be remobilized. Patients diagnosed with MM who following relapse after auto-HSCT, had remobilization and afterward, auto-HSCT with remobilized cells were included in this retrospective analysis.

Stem cell mobilization in multiple myeloma patients relapsing after previous autologous hematopoietic stem cell transplantation: A multicenter report by the Polish Myeloma Study Group.

Background: Salvage autologous hematopoietic stem cell transplantation (autoHSCT) may be used to treat relapse of multiple myeloma occurring after previous autoHSCT. When insufficient number of hematopoietic stem cells was stored from the initial harvest, remobilization of stem cells is necessary.

Purpose: The analysis of stem cell remobilization after previous autoHSCT.

Characteristics and homogeneity of N6-methylation in human genomes.

A novel DNA modification, N-6 methylated deoxyadenosine (m6dA), has recently been discovered in eukaryotic genomes. Despite its low abundance in eukaryotes, m6dA is implicated in human diseases such as cancer. It is therefore important to precisely identify and characterize m6dA in the human genome.

Bioinformatics challenges and perspectives when studying the effect of epigenetic modifications on alternative splicing.

It is widely known that epigenetic modifications are important in regulating transcription, but several have also been reported in alternative splicing. The regulation of pre-mRNA splicing is important to explain proteomic diversity and the misregulation of splicing has been implicated in many diseases. Here, we give a brief overview of the role of epigenetics in alternative splicing and disease.

Identification of Methylated Deoxyadenosines in Genomic DNA by dA DNA Immunoprecipitation.

Unlabelled: dA DNA immunoprecipitation followed by deep sequencing (DIP-Seq) is a key tool in identifying and studying the genome-wide distribution of N-methyldeoxyadenosine (dA). The precise function of this novel DNA modification remains to be fully elucidated, but it is known to be absent from transcriptional start sites and excluded from exons, suggesting a role in transcriptional regulation (Koziol , 2015). Importantly, its existence suggests that DNA might be more diverse than previously believed, as further DNA modifications might exist in eukaryotic DNA (Koziol , 2015).

Assessment of skin-related toxicity in patients with metastatic colorectal cancer treated with cetuximab.

Monoclonal antibodies (mAbs) blocking the epidermal growth factor receptor (EGFR) pathway, such as cetuximab, have been widely used in recent years for the treatment of metastatic colorectal cancer (mCRC). The purpose of this study was to evaluate the profile of the side effects of cetuximab affecting the skin and its appendages. We gathered the medical records on skin-related toxicity in 46 patients treated with cetuximab for mCRC in the Department of Clinical Oncology, University Hospital in Krakow in 2009-2013.

[PARP inhibitors and their role in the therapy of triple-negative metastatic breast cancer].

Breast cancer is the most common neoplasm among women. The risk of disease increases with age, particularly in postmenopausal period. The method of treatment depends on the stage of disease, state of receptors and molecular subtype.

TCTP in development and cancer.

The translationally controlled tumor protein (TCTP) is highly conserved among animal species. It is widely expressed in many different tissues. It is involved in regulating many fundamental processes, such as cell proliferation and growth, apoptosis, pluripotency, and the cell cycle.

Integrative annotation of human large intergenic noncoding RNAs reveals global properties and specific subclasses.

Large intergenic noncoding RNAs (lincRNAs) are emerging as key regulators of diverse cellular processes. Determining the function of individual lincRNAs remains a challenge. Recent advances in RNA sequencing (RNA-seq) and computational methods allow for an unprecedented analysis of such transcripts.

A large intergenic noncoding RNA induced by p53 mediates global gene repression in the p53 response.

Recently, more than 1000 large intergenic noncoding RNAs (lincRNAs) have been reported. These RNAs are evolutionarily conserved in mammalian genomes and thus presumably function in diverse biological processes. Here, we report the identification of lincRNAs that are regulated by p53.

The effect of silver nanoparticles on phytopathogenic spores of Fusarium culmorum.

The aim of the present experiment was to investigate the influence of silver nanoparticles on Fusarium culmorum (W.G. Smith) Sacc.

Ab initio reconstruction of cell type-specific transcriptomes in mouse reveals the conserved multi-exonic structure of lincRNAs.

Massively parallel cDNA sequencing (RNA-Seq) provides an unbiased way to study a transcriptome, including both coding and noncoding genes. Until now, most RNA-Seq studies have depended crucially on existing annotations and thus focused on expression levels and variation in known transcripts. Here, we present Scripture, a method to reconstruct the transcriptome of a mammalian cell using only RNA-Seq reads and the genome sequence.

RNA traffic control of chromatin complexes.

It is widely accepted that the genome is regulated by histone modifications that induce epigenetic changes on the genome. However, it is still not understood how ubiquitously expressed chromatin modifying complexes are 'guided' to specific genomic sites to induce intricate patterns of epigenetic modifications. Previously believed to represent 'genome junk', it is now becoming increasingly clear that large non-coding RNAs associate with chromatin modifying complexes.

Tpt1 activates transcription of oct4 and nanog in transplanted somatic nuclei.

Nuclear transfer to eggs or oocytes provides a potential route for cell-replacement therapies because oocytes directly reprogram transplanted mammalian somatic-cell nuclei such that they have an embryo-like pattern of gene expression. This includes a large increase in the mRNA level of the stem-cell marker gene oct4. We have developed a novel procedure to identify new proteins that greatly increase the level of oct4 mRNA upon nuclear transfer.
