RESUMO

India is presently undergoing a rapid demographic transition and experiencing a gradual increase in an ageing population. As a result, the households were continuously exposed to catastrophic economic impacts, ultimately influencing the healthcare utilisation of older people. The study examined the gender differentials in the choice of in-patient private and public hospitalisation among Indian elderly using Andersen's Health Behaviour Model. The database was acquired from the nationally representative cross-sectional survey (NSSO, 2017-18). Bivariate chi-square and binomial logistic regression techniques were used to fulfill the objective. In addition, the poor-rich ratio and concentration index was used to understand the inherent socioeconomic inequalities in healthcare preferences. The findings suggest that aged men were 27 percent more prone to avail private healthcare facilities than aged women. Further, older adults, who are married, belong to the upper caste, have higher education and gone through surgery, and primarily reside in an affluent society were more likely to prefer private in-patient hospitalisation. It represents negligence of older women in access to better healthcare who had financial strain and economically dependent. The study can be used to reframe existing public health policies and programs, particularly focusing on the older women, to avail cost-effective treatment.

RESUMO

Multiple myeloma (MM), second most common hematological malignancy, still remains beyond cure because of acquirement of drug resistance. Proteasome inhibitor such as carfilzomib (Cfz) therapy which has been used as one of the key therapies against MM recently, is obstructed by the incidence of Cfz resistance. The underlying mechanism of this acquired Cfz resistance in MM is very little understood. Therefore, the current study was aimed to investigate the differentially expressed genes (DEGs), associated micro RNAs (miRNAs), and transcription factors (TFs) from the microarray datasets of Cfz resistant and Cfz sensitive MM cell lines, obtained from Gene Expression Omnibus (GEO) database. DEGs were detected using GEO2R tool from two datasets and common DEGs were identified through Venn diagram. Gene ontology (GO) and pathway enrichment analysis were performed on DAVID database. Through STRING database and Cytoscape tool, protein-protein interaction (PPI) network of DEGs was constructed. Genetic alterations in DEGs were investigated using COSMIC database. Interaction network between DEGs and miRNAs as well as TFs were obtained and constructed by using mirDIP, TRRUST, and miRNet tools. Drug gene interaction analysis was performed to identify potential drug molecules on DGIdb tool. Several common DEGs were identified in Cfz resistant MM. PDGF, VEGF, and Wnt signaling pathways were significantly enriched and might be involved in MM progression. miRNA analysis identified hsa-mir-124-3p, hsa-mir-26a-5p that can target DEGs. Various drug molecules such as dabrafenib, vemurafenib, and venetoclax that could potentially attenuate the MM pathophysiology, were detected. The entire study might provide a new understanding about the Cfz resistance in MM.

RESUMO

Multiple myeloma (MM), second most common hematological malignancy, still remains irremediable because of acquisition of drug resistance. Glucocorticoid (GC) therapy, which is used as one of the key therapies against MM, is hindered by the incidence of GC resistance. The underlying mechanism of this acquired GC resistance in MM is not fully elucidated. Therefore, the present study was aimed to identify the differentially expressed genes (DEGs), associated micro RNAs (miRNAs), and transcription factors (TFs) from the microarray datasets of GC-resistant and GC-sensitive MM cell lines, obtained from Gene Expression Omnibus (GEO) database. DEGs were identified using GEO2R tool from two datasets and common DEGs were obtained by constructing Venn diagram. Then the Gene ontology (GO) and pathway enrichment analysis were performed using DAVID database. Genetic alterations in DEGs were examined using COSMIC database. Protein-protein interaction (PPI) network of DEGs was constructed using STRING database and Cytoscape tool. Network of interaction of DEGs and miRNAs as well as TFs were obtained and constructed using mirDIP, TRRUST, and miRNet tools. Drug gene interaction was studied to identify potential drug molecules by DGIdb tool. Six common DEGs, CDKN1A, CDKN2A, NLRP11, BTK, CD52, and RELN, were found to be significantly upregulated in GC-resistant MM and selected for further analysis. miRNA analysis detected hsa-mir-34a-5p that could interact with maximum target DEGs. Two TFs, Sp1 and Sp3, were found to regulate the expression of selected DEGs. The entire study may provide a new understanding about the GC resistance in MM.

RESUMO

In recent years, an explosion of interest for genome methylation in hematopoietic stem cells (HSCs) differentiation and transplantation has been observed. The differentiation and timely proliferation of HSCs require a stringent regulation of gene expression; this can't be maintained without the regulation of genome methylation. Evidences of changes in genome methylation patterns in healthy and cancer cells have opened a new paradigm for diagnostic and therapeutic strategies. Genome methylation or DNA methylation is achieved by DNA methyltransferases (DNMTs) through the transfer of methyl group leading to the regulation of gene's expression. Till now five DNMTs have been found in mammals, known as DNMT1, DNMT2, DNMT3A, DNMT3B and DNMT3L. In this review, we have carefully evaluated the spacio-temporal landscape expression and role of DNMTs during hematopoiesis, hematopoietic malignancy and HSCs transplantation. Focusing on the connection of DNA methylation with gene expression in association with cellular signalling, histone modifications, it is proposed for further improvement of strategies to use DNA methylation as a marker in clinical diagnosis as well as in therapeutic interventions by applying DNMTs inhibitors.
