对癌发生和肿瘤进展的分子理解依赖于肿瘤内和肿瘤间的异质性。实体瘤局限于各种各样的遗传异常、表观遗传修饰和环境因素,这些因素在肿瘤起始、进展和转移的每个阶段都不同。通过常规分子技术研究的肿瘤内的复杂性未能识别个体中基质和免疫细胞中的不同亚类,并且影响免疫治疗。在这里,我们专注于基质细胞群和免疫居民的多样性,其亚型创造了肿瘤微环境(TME)的复杂性,导致原发性肿瘤发展为晚期癌症。单细胞测序(表位分析)方法的最新进展限制了单个细胞的表型标记、分子途径和进化轨迹。我们讨论了目前的知识,基质和免疫细胞亚类在癌症发展的不同阶段与非编码RNA的调节作用。最后,我们报告了目前免疫治疗的治疗选择,靶向异质性治疗的进展和可能的结果。
The molecular understanding of carcinogenesis and tumor progression rests in intra and inter-tumoral heterogeneity. Solid tumors confined with vast diversity of genetic abnormalities, epigenetic modifications, and environmental cues that differ at each stage from tumor initiation, progression, and metastasis. Complexity within tumors studied by conventional molecular techniques fails to identify different subclasses in stromal and immune cells in individuals and that affects immunotherapies. Here we focus on diversity of stromal cell population and immune inhabitants, whose subtypes create the complexity of tumor microenvironment (TME), leading primary tumors towards advanced-stage cancers. Recent advances in single-cell sequencing (epitope profiling) approach circumscribes phenotypic markers, molecular pathways, and evolutionary trajectories of an individual cell. We discussed the current knowledge of stromal and immune cell subclasses at different stages of cancer development with the regulatory role of non-coding RNAs. Finally, we reported the current therapeutic options in immunotherapies, advances in therapies targeting heterogeneity, and possible outcomes.
