Notably, increased <em>Lgals2<\/em> expression levels <em>in vivo<\/em>\u2014but not <em>in vitro<\/em>\u2014correlated with enhanced tumor cell proliferation. scRNA-seq further revealed multiple transcriptional clusters of immune cells altered in <em>Lgals2<\/em>-overexpressing mice. In particular, the scRNA-seq data pointed to macrophage compartment remodeling induced by tumor cell overexpression of <em>Lgals2<\/em>. Subsequent experiments showed that anti-LGALS2 antibody treatment slowed tumor growth and decreased macrophage proliferation, thus demonstrating the value of transcriptomics in identifying potential therapeutic targets.<\/p>\n<p><strong>Reveal potential prognostic marker<\/strong><\/p>\n<p>Because the tumor microenvironment (TME) influences factors such as tumor progression, treatment resistance, and metastasis,<sup>[2]<\/sup> understanding the TME is also important for considering prognostic factors and therapeutic targets. Luo et al. employed Novogene\u2019s single-cell transcriptomic sequencing capabilities to comprehensively profile the commonalities, heterogeneities, and plasticity of cancer-associated fibroblasts (CAFs) which are the predominant component of the TME.<sup>[2] <\/sup>Luo et al. developed a single-cell transcriptional atlas for common solid cancer types from public and in-house scRNA-seq data to systematically characterize CAFs across cancers. Notably, they found that CAFs had multiple states of differentiation, each with specific biofunctions. In particular, the most de-differentiated state predicted worse immunotherapy outcomes, suggesting that evaluating a patient\u2019s CAF differentiation state may be prognostic for immunotherapy decisions.<\/p>\n<p><strong>Uncover potential therapeutic targets <\/strong><\/p>\n<p>Single-cell transcriptome sequencing technologies have considerable applicability beyond cancer. For example, Liu et al. used single-cell transcriptional profiling of bone marrow (BM) hematopoietic stem cells (HSPCs) to investigate potential contributions of hematopoietic differentiation to ITP (immune thrombocytopenia) pathogenesis.<sup>[3]<\/sup> Analyses of their single-cell transcriptomic atlas of HSPCs in ITP BM versus healthy controls revealed multiple transcriptome alterations in hematopoiesis during ITP, including activation of immune states during most phases. In another example, Tang et al. used single-cell multi-omics technology to investigate MAIT (mucosal-associated invariant T) cell dysfunction in HIV-1 infected individuals, a phenomenon which contributes to vulnerability to bacterial infection.<sup>[4]<\/sup> Using a combination of Abseq (oligo-conjugated antibodies) and scRNA-seq, they developed transcriptomic and proteomic expression profiles. Analyzing those profiles revealed that MAIT cells in HIV-1-infected patients were characterized by immune activation, suggesting a role for IFN-I activation. Additional experiments showed that MAIT cells\u2019 antibacterial response could be restored in vitro by blocking IFNAR or IL-10R. Together, these studies illustrate how transcriptome profiling strategies, and in particular single-cell transcriptional profiling, can elucidate characteristics of cell types within very different diseases that can then be used to identify potential therapeutic targets or pathways.<\/p>\n<p>In conclusion, single cell sequencing techniques have the potential to revolutionize drug development by uncovering potential therapeutic targets and improving patient outcomes. By providing unprecedented insights into cellular behavior and function, these techniques can help identify rare cell populations, genetic mutations, and treatment response predictors that may be missed by traditional sequencing methods. As technology continues to advance, single cell sequencing is likely to become an increasingly important tool in the fight against diseases.<\/p>\n<p><strong>References<\/strong><\/p>\n<p>[1].
