Review is devoted to systems for drug delivery of biologically active substances in the tissues and organs of the target cells, which is relevant to medicine. There are described properties of mesenchymal stromal cells (MSCs), which many authors propose to use…
MicroRNAs (miRNAs) – small non-coding RNAs targeting multiple mRNAs – are posttranscriptional regulators of gene expression involved in carcinogenesis, metastasis, and invasion. MiRNAs expression is altered in various human tumors including ovarian cancer. Ana…
Genes encoding proteins of IAP (Inhibitor of apoptosis proteins) have increased expression in the cells of malignant tumors of different localizations. IAPs perform several functions related to the viability of cancer cells and their subsequent proliferation. …
Introduction. Currently in the world there are conducted numerous studies on the search for biomarkers associated with increased risk of coronary heart disease (CHD). The aim of the study. The study of the levels of such inflammatory biomarkers as the tumor ne…
Introduction. Insulin-like growth factors (IGF) signaling system plays a major role in the development and progression of various sarcomas and other solid tumors, and therefore its components are regarded as promising diagnostic and prognostic tumor markers an…
Introduction. IGF-1R in breast cancer tumor tissue was shown to be expressed in large quantities in comparison with benign tumor or normal breast tissue. At the same time, IGF-1 stimulates proliferation of normal and tumor breast cells. The aim of the study. T…
Introduction. Mutations in the tumor suppressor gene TP53 are observed approximately in the half of all human malignancies. In bladder cancer (BC), ТР53 molecular alterations were shown to be associated with more aggressive tumor phenotype; however their clini…
Introduction: Insulin-like growth factors (IGFs), insulin-like growth factor-I receptor (IGF-IR), IGR-binding proteins (IGFBPs) and IGBP proteases can play an important role in the development of metastases in ovarian cancer. The relationship between IGF syste…
Introduction. Hormonal aspect in the pathogenesis of melanoma development is still poorly studied. Tumor transplantation to experimental animals allows to study the effect of malignant process on different systems and organs, detect the saturation of tumor and…
Introduction. According to modern understanding, oxidative stress along with apoptosis dysregulation plays an important role in the pathogenetic mechanisms of tumor growth; formation of oxidative stress is accompanied by oxidative modification of cell protein …
Introduction. Nuclear medicine imaging is widely used in oncology for the assessment of pathophysiologic changes occurring in a tumor. In this regard, the intensive study of diagnostic efficiency of the existing radiopharmaceuticals and the search for the new …
Introduction. Targeted gene delivery plays an exceptional role in the development of gene therapy. Peptide-based carriers are promising group of non-viral gene delivery vehicles due to biodegradability and easy structural and amino acid sequence modifications.…
Introduction. Most cases of gastric cancer (GC) occur sporadically. Until recently, diffuse hereditary gastric cancer associated with the CDH1 gene mutations was considered the only hereditary form (about 1–3% of all tumors of the stomach). However, a signific…
Introduction. KRAS mutations play a critical role in human tumorigenesis and are the most prevalent in colorectal cancer. Because KRAS is the most frequently mutated factor downstream of the EGFR signaling pathway, it was considered to be a candidate molecular…
Introduction. The elevated expression of components of DNA repair system ERCC1 (excision repair cross-complementing group 1) and XPD (Xeroderma pigmentosum group D) is associated with the lack of efficacy of DNA–damaging cytotoxic platinum-based preparations. …
Introduction. Gastrointestinal stromal tumors (GISTs), the most common mesenchymal tumors of GI tract, are characterized by KIT and PDGFRA activating mutations that are predictive factors. KIT and PDGFRA mutations are present in 85% of GISTs and are associated…
Hepatocellular carcinoma (HCC) is the most prevalent form of malignant liver cancer characterized by late detection time and highly aggressiveness. The main risk factors for HCC development are chronic infections of hepatitis B and C viruses, cirrhosis, liver …
There is represented immunohistochemical and molecular biological characteristic of some histological types of breast cancer. The assessment of molecular biomarkers in breast cancer has two practical results: identification of risk groups, requiring additional…
The key role in the achievement of the main goals of personalized medicine in oncology i.e. treatment choice according to patient’s individual characteristics and biological properties of the tumor belongs to tumor molecular markers characterizing the specific…
The formation of properties promoting malignant transformation begins before the appearance of tumor cells at the level of inflammatory and precancerous processes. The basis for these properties is genomic instability of tumor cells. Genetic instability manife…
