Precision genome editing holds immense promise for the treatment of genetic disorders, but efficient in vivo delivery of CRISPR-Cas9 components remains a formidable challenge. This article explores the development and application of targeted nanoparticles as a delivery platform for the CRISPR-Cas9 system. We discuss the design, optimization, and in vivo testing of nanoparticles tailored to specific cell types and tissues. The integration of nanotechnology and genome editing not only enhances the precision and efficiency of genome modifications but also paves the way for potential therapeutic breakthroughs.

The study of single-cell heterogeneity is a fundamental aspect of understanding complex biological systems. This article explores the transformative capabilities of quantitative Imaging Flow Cytometry (qIFC) in unraveling the intricacies of single-cell analysis. We discuss the principles, instrumentation, and data analysis techniques associated with qIFC, emphasizing its capacity to provide quantitative and spatial information at the single-cell level. This technology enables comprehensive investigations into cell populations, revealing hidden phenotypic diversity, dynamic responses, and subcellular features. The integration of qIFC is poised to advance our knowledge of cellular biology, immunology, and disease mechanisms.

By harnessing the power of mass spectrometry, machine learning, and bioinformatics, researchers are making significant strides towards revolutionizing disease diagnosis and personalized treatment strategies.

Beta thalassemia is a disorder in which the body is unable to synthesise haemoglobin beta subunit due to deleterious mutations in the β-globin gene that results in underproduction of Adult Haemoglobin (HbA). Fetal Haemoglobin (HbF), which is composed of two α and two γ subunits, has been identified as a potential substitute for HbA with great clinical significance in β-thalassaemic patients. However, in the developmental stages, the expression of HbF is gradually minimized and overtaken by HbA. Our research found that the investigation of blood expression and its relationship to DEGs may aid in elucidating the role of these DEGs in beta thalassemia progression, and an RNA sequencing study indicated that the β globin gene is down regulated. There are 200 genes that are differently expressed in β thalassemia patients compared to healthy controls, as well as two key genes. KLF1 and MDM2 are two potential target genes for beta thalassemia patients that could be employed as diagnostic indicators. The differentially expressed genes include genes involved in heme biosynthesis, heme binding, erythrocyte homeostasis, iron ion binding, erythrocyte differentiation, gas transport and response to oxygen species metabolic processes, and other cellular processes. However, functional studies are needed to confirm their proposed relevance in beta thalassemia.
