Precision medicine for cancer patients aims to adopt the most suitable treatment options during diagnosis and treatment of individuals. Detecting circulating tumor cell (CTC) or circulating tumor DNA (ctDNA) in plasma or serum could serve as liquid biopsy, which would be useful for numerous diagnostic applications. Liquid biopsies can help clinicians screen and detect cancer early, stratify patients to the most suitable treatment and real-time monitoring of treatment response and resistance mechanisms in the tumor, evaluate the risk for metastatic relapse, and estimate prognosis. We summarized the advantages and disadvantages of tissue and liquid biopsies. We also further compared and analyzed the advantages and limitations of detecting CTCs, ctDNAs, and exosomes. Furthermore, we reviewed the literature related with the application of serum or plasma CTCs, ctDNAs, and exosomes for diagnosis and prognosis of cancer. We also analyzed their opportunities and challenges as future biomarkers. In the future, liquid biopsies could be used to guide cancer treatment. They could also provide the ideal scheme to personalize treatment in precision medicine.

Cancer stem cells (CSCs) have received considerable attention from the research community since they were first reported in human acute myeloid leukemia 15 years ago. Accumulating evidence suggests that CSCs are responsible for tumor initiation and progression, drug resistance, and metastasis in both liquid and solid tumors. These findings lead to the development of novel compounds targeting CSC populations that is becoming increasingly important for eradicating CSCs in heterogeneous tumor masses and to cure the cancer. Since 2003, we have participated in CSC studies and encountered crucial early events in the field. This article reviews the history of CSC biology, clarifies the term and its definition, and further addresses the issue of how to utilize CSCs in therapeutic target discovery and drug development based on our substantial experience.

由于聚合物芯片实验室具有高度的精准性和灵活性,将其用于设计和制造的快速原型制作方法正在兴起。例如,一个微流控平台可能需要优化阶段,而在此阶段需要不断修改结构和几何形状;然而,这只有在具有简易可控的制造方法和低成本材料的情况下才可能实现。本文描述了一个微流控工具的实现过程,从计算机辅助设计(CAD)到作为循环肿瘤细胞(CTC)捕获工具应用的概念验证。整个平台通过使用聚甲基丙烯酸甲酯(PMMA)及结合飞秒(fs)激光和微铣制造技术实现。该多层设备通过一种简便、低成本的溶剂辅助方法组装。然后通过固定能够在没有标记的情况下区分癌细胞与非癌细胞的捕获探针,实现蛇形微通道的直接生物功能化。由于低材料成本、可定制的方法以及可生物应用,已实现的平台成为即时医疗工业开发与应用的合适模型。

Paradoxical role of Id proteins in regulating tumorigenic potential of lymphoid cells

A family of transcription factors known as Id proteins, or inhibitor of DNA binding and differentiation, is capable of regulating cell proliferation, survival and differentiation, and is often upregulated in multiple types of tumors. Due to their ability to promote self-renewal, Id proteins have been considered as oncogenes, and potential therapeutic targets in cancer models. On the contrary, certain Id proteins are reported to act as tumor suppressors in the development of Burkitt’s lymphoma in humans, and hepatosplenic and innate-like T cell lymphomas in mice. The contexts and mechanisms by which Id proteins can serve in such contradictory roles to determine tumor outcomes are still not well understood. In this review, we explore the roles of Id proteins in lymphocyte development and tumorigenesis, particularly with respect to inhibition of their canonical DNA binding partners known as E proteins. Transcriptional regulation by E proteins, and their antagonism by Id proteins, act as gatekeepers to ensure appropriate lymphocyte development at key checkpoints. We re-examine the derailment of these regulatory mechanisms in lymphocytes that facilitate tumor development. These mechanistic insights can allow better appreciation of the context-dependent roles of Id proteins in cancers and improve considerations for therapy.

The existence of cancer stem cells, stem-like cancer cells (SLCCs), or tumor-initiating cells is considered as the cause of tumor formation and recurrence, indicating the importance of studying novel therapy that targets SLCCs. The origin of SLCCs is controversial because of two competing hypotheses: SLCCs are either transformed from tissue adult stem cells or dedifferentiated from transformed progenitor cells. Our previous research demonstrates that SLCCs are inducible by increasing genomic instability in cancer cells. In this study, to block the emergence of SLCCs, aminoethyl isothiourea (AET), a compound that clears free radicals and is used to protect patients from radioactive exposure, was used as an agent that maintains genomic stability in combination with mitomycin C (MMC), a commonly used chemotherapeutic drug that damages DNA. Using a rabbit tumor model with VX2 hepatic carcinoma, we found that MMC alone increased lung metastases and disadvantaged survival outcome, but the combination of MMC and AET reversed this effect and even prolonged overall survival. Moreover, in a VX2 xenograft model by immunocompromised mice, MMC alone enriched tumor-initiating cells, but the administration of MMC in combination with AET eliminated tumor cells effectively. Furthermore, MMC alone enhanced genomic instability, but MMC combined with AET attenuated the extent of genomic instability in primary VX2 tumor tissue. Taken together, our data suggest that the genomic protector AET can inhibit the induction of SLCCs, and this combination treatment by AET and cytotoxic agents should be considered as a promising strategy for future clinical evaluation.

Evaluating the effects of novel drugs on appropriate tumor models has become crucial for developing more effective therapies that target highly tumorigenic and drug-resistant cancer stem cell (CSC) populations. In this study, we demonstrate that a subset of cancer cells with CSC properties may be enriched into tumor spheroids under stem cell conditions from a non-small cell lung cancer cell line. Treating these CSC-like cells with gemcitabine alone and a combination of gemcitabine and the novel CHK1 inhibitor PF-00477736 revealed that PF-00477736 enhances the anti-proliferative effect of gemcitabine against both the parental and the CSC-like cell populations. However, the CSC-like cells exhibited resistance to gemcitabine-induced apoptosis. Collectively, the spheroid-forming CSC-like cells may serve as a model system for understanding the mechanism underlying the drug resistance of CSCs and for guiding the development of better therapies that can inhibit tumor growth and eradicate CSCs.
