    Aim. To develop the model system for processing bodies (PBs) state monitoring and accomplish it in the future as a possible read-out of mTOR activity in mammalian cells. Methods. In course of this study we raised polyclonal antibodies against one of the PBs scaffold proteins – RCD-8 and employed cell imaging technique. Results. It has been shown that the obtained antibodies recognize the intracellular structures, namely PBs. The detected protein co-localized with known marker of PBs – DCP1a, and partly with marker of SGs – CPEB. Conclusions. Based on changes of PBs number and size in cells after exposure to known inductors or inhibitors of PB formation we prove the specificity of generated antibodies and possibility of their application for studies on the processing bodies dynamics controlled by mTOR-dependent signalin

    IGHV3-21 gene expression in patients with b-cell chronic lymphocytic leukemia in Ukraine

    No full text
    The aim of the study was to evaluate the frequency of IGHV3-21 gene usage and its clinical significance for patients with B-cell chronic lymphocytic leukemia (CLL) in Ukraine. Patients and Methods: Immunoglobulin variable heavy chain (IGHV) gene repertoire was studied in 189 CLL patients using reverse transcribed polymerase chain reaction and direct sequence of amplified products. Results: IGHV3-21 gene expression was found in 11 cases (5.8%), and its frequency was intermediate between Scandinavian (11.7%) and Mediterranean CLL (2.9%) cohorts. The most of cases (9 of 11) belonged to subset with heterogeneous HCDR3 (heteroHCDR3 subset), and only 2 cases – to subset with classical short ARDANGMDV motif (homHCDR3 subset). Six IGHV3-21 cases were mutated and 5 cases were unmutated. All unmutated cases (all were from heteroHCDR3 subset) had similarity of their HCDR3s with previously published sequences. The differences in overall (OS), progression-free (PFS) and treatment-free survival (TFS) for IGHV3-21 positive patients in comparison with CLL patients expressing the other IGHV genes were statistically insignificant. These survival parameters were comparable also for CLL patients with mutated IGHV3-21 gene usage and expression the others mutated IGHV genes. But remarkable feature of IGHV3-21 expressing patients was high incidence of solid tumors. They have developed in 4 IGHV3-21 positive cases (36.4%) and in 10 cases with expression of the others IGHV genes (5.6%, p = 0.0002). Furthermore, in small group of 6 patients with mutated IGHV3-21 gene expression, 3 patients had solid tumors and one underwent Richter transformation. Unmutated IGHV3-21 gene expressed patients had worse OS and PFS in comparison with CLL patients that expressed the others unmutated IGHV genes. Conclusion: Presented data are in agrement with the opinion about negative prognostic significance of IGHV3-21 gene expression regardless its mutation status. IGHV3-21 expression was associated with development of secondary solid tumors. Revealed high level of homology in heteroHDR3s subset might suggest about possible antigenic influence also, in addition to homHCDR3 subset that was proposed earlier.ЦСль: ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ частоту использования Π³Π΅Π½Π° IGHV3-21 ΠΈ Π΅Π³ΠΎ клиничСскоС Π·Π½Π°Ρ‡Π΅Π½ΠΈΠ΅ для Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ… B-ΠΊΠ»Π΅Ρ‚ΠΎΡ‡Π½Ρ‹ΠΌ хроничСским Π»ΠΈΠΌΡ„ΠΎΠ»Π΅ΠΉΠΊΠΎΠ·ΠΎΠΌ (Π₯Π›Π›) Π² Π£ΠΊΡ€Π°ΠΈΠ½Π΅.

    Background: Eribulin mesylate was initially approved in 2010 by FDA as a third-line treatment for women with advanced breast cancer (ABC) pretreated with at least two lines of chemotherapy, and then in 2011 it was approved by EMA as a second-line therapy. Patients should have received an anthracycline and a taxane in either the adjuvant or metastatic setting. Since then, several studies have been conducted confirming its efficacy and safety. We report our experience of using eribulin in our centre in a real-life clinical setting.Materials and methods: 34 patients with ABC were enrolled to receive eribulin. From February 2016 to February 2017, patients were treated with standard doses of eribulin and evaluated for toxicity and responses. All of them had previously received anthracyclines and taxanes in either the adjuvant or metastatic setting. Median age was 60 years (range: 39–79). ECOG performance status was 1 or 2 at the time of enrollment. Median number of cycles of eribulin was 5 (range 2–10). Patients received eribulin from first-line chemotherapy to seventh-line chemotherapy for ABC. Median number of envolved visceral organs was 2 (range 1–4).Results: There were no complete responses. Partial responses were achieved in 26.4% (9/34), stabilization of the disease in 32.4% (11/34) and progression of the disease in 41.2% (14/34) of patients. The median progression-free survival was 4.09 months (range: 2.6–6.53). Main toxicities (grade 3–4) included peripheral neuropathy and neutropenia. Neuropathy was marked in 14.7% (5/34) and neutropenia in 14.7% (5/34) of patients. Dose reductions were required in 14.7% (5/34) of patients because of neutropenia.Conclusion: Our experience shows that eribulin has clinical activity as well as satisfactory tolerability in unselected patients in a reallife clinical setting. Thus, in our opinion, eribulin can represent a new option in treatment of ABC patients.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅: Π­Ρ€ΠΈΠ±ΡƒΠ»ΠΈΠ½ Π²ΠΏΠ΅Ρ€Π²Ρ‹Π΅ Π±Ρ‹Π» зарСгистрирован FDA Π² 2010 Π³.

    The article describes a clinical example of timely, safe and effective photodynamic therapy (PDT) in a patient diagnosed with human papillomavirus (HPV) CIN I-associated cervical cancer after ineffective vaccination with 4-valent Gardasil vaccine. Clinical case demonstrates the low effectiveness of HPV vaccination in patients with established HPV infection. In this patient, the lack of adequate treatment for about 1.5 years led to the development of HPV associated CIN I of the cervix. Center for Laser and Photodynamic Diagnostics and Therapy of Tumors and MRI P.A.

    Regulation of the CoA Biosynthetic Complex Assembly in Mammalian Cells

    Coenzyme A (CoA) is an essential cofactor present in all living cells. Under physiological conditions, CoA mainly functions to generate metabolically active CoA thioesters, which are indispensable for cellular metabolism, the regulation of gene expression, and the biosynthesis of neurotransmitters. When cells are exposed to oxidative or metabolic stress, CoA acts as an important cellular antioxidant that protects protein thiols from overoxidation, and this function is mediated by protein CoAlation. CoA and its derivatives are strictly maintained at levels controlled by nutrients, hormones, metabolites, and cellular stresses. Dysregulation of their biosynthesis and homeostasis has deleterious consequences and has been noted in a range of pathological conditions, including cancer, diabetes, Reye’s syndrome, cardiac hypertrophy, and neurodegeneration. The biochemistry of CoA biosynthesis, which involves five enzymatic steps, has been extensively studied. However, the existence of a CoA biosynthetic complex and the mode of its regulation in mammalian cells are unknown. In this study, we report the assembly of all five enzymes that drive CoA biosynthesis, in HEK293/Pank1Ξ² and A549 cells, using the in situ proximity ligation assay. Furthermore, we show that the association of CoA biosynthetic enzymes is strongly upregulated in response to serum starvation and oxidative stress, whereas insulin and growth factor signaling downregulate their assembly

    Raman fingerprints of ultrasmall nanodiamonds produced from adamantane

    The synthesis of ultrasmall (2-5 nm) nanodiamonds purely from adamantane at pressure of 12 GPa is reported. Their structural features have been studied by Raman spectroscopy. The unusual vibration band containing a number of pronounced maxima at about 1147, 1245, 1344, and 1456 cm-1 was detected in Raman spectra. The band is confidently identified with the bending vibrational modes of CHx groups terminating the nanodiamonds surface. Excessively intense mode at 1344 cm-1 is explained by its coupling with the 1328 cm-1 diamond phonons. The Raman band found is proposed to be used for express recognition of ultrasmall nanodiamonds produced from adamantane and other hydrocarbons with a high hydrogen content. Moreover, polarized CH bonds on a diamond surface are sensitive to environmental conditions. This opens up opportunities for using the diamond produced from adamantane as ultrasmall nanosensors in biology, chemistry, and medicineComment: 12 pages, 6 figure
