Bone metastases can disseminate to secondary sites and promote breast cancer progression creating additional clinical challenges. The mechanisms contributing to secondary metastasis are barely understood. Here, we evaluate the prediction power of Her2-expressing (Her2E) circulating tumor cells (CTCs) after analyzing over 13,000 CTCs from a cohort of 137 metastatic breast cancer (MBC) patients with initial HR+/Her2- status and employ preclinical models of bone metastasis (BM) to validate the role of Her2E CTCs in multi-organ metastases. While Her2 expression was higher in patients with bone metastasis, experimental analyses revealed that Her2E CTCs derived from bone lesions were more dependent on Her2 activity and more susceptible to anti-Her2 therapy. Targeting the bone-mediated Her2 induction reduces CTC detection and abrogates secondary metastasis from bone. Overall, we elucidate that Her2E CTCs can serve as a non-invasive biomarker for BM formation with high therapeutic benefit for HR+ MBC patients.

The role of ubiquitin-mediated degradation mechanisms in the pathogenesis of diffuse large B cell (DLBCL) and follicular lymphoma (FL) is not completely understood. We show that conditional deletion of the E3 ubiquitin ligase Fbxo45 in germinal center B-cells results in B-cell lymphomagenesis in homozygous (100%) and heterozygous (48%) mice. Mechanistically, FBXO45 targets the RHO guanine exchange factor ARHGEF2/GEF-H1 for ubiquitin-mediated degradation. Double genetic ablation of Fbxo45 and Arhgef2 ameliorated lymphoma formation. Transgenic knock-in mice harboring a GEF-H1 mutant unable to bind FBXO45 develop B-cell lymphomas with ~50% penetrance. Genome sequencing in human lymphomas identified mutually-exclusive FBXO45 copy number losses and ARHGEF2 gains, with combined frequencies ranging from 26.32% in FL to 45.12% in DLBCL. Notably, FBXO45 silencing enhances sensitivity to MEK1/2 inhibition. These results identify FBXO45 and ARHGEF2 as a novel tumor-suppressor and oncogene pair involved in the pathogenesis of B-cell lymphomas with significant implications for targeted therapies.

PIN1 prolyl isomerase promotes initiation and progression of bladder cancer through the SREBP2-mediated cholesterol biosynthesis pathway PIN1 脯氨酰异构酶通过 SREBP2 介导的胆固醇生物合成途径促进膀胱癌的发生和发展

Identities of functional pSer/Thr.Pro protein substrates of the PIN1 prolyl isomerase and its effects on downstream signaling in bladder carcinogenesis remain largely unknown. Phenotypically, we found that PIN1 positively regulated bladder cancer cell proliferation, cell motility and urothelium clearance capacity in vitro and controlled tumor growth and potential metastasis in vivo. Mechanistically, we observed a negative enrichment of SREBP2-driven cholesterol metabolism pathways and a decrease in free/total cholesterol levels in PIN1-knockout bladder cancer cells. Moreover, we showed that PIN1 interacted with SREBP2 following its phosphorylation by the JNK MAP kinase at Ser455, which lies near the Site-2 cleavage site that generates the active, nuclear-form of SREBP2. Therapeutically, a combination of the sulfopin PIN1 covalent inhibitor and the simvastatin HMGCoA reductase inhibitor suppressed cell proliferation in vitro and tumor growth in vivo synergistically. Together, these findings emphasize that PIN1 can act as a driver and potential therapeutic target in bladder cancer.

Significance: Our study harnesses a CRISPR-based method to examine ecDNA biogenesis, uncovering efficient circularization between double-strand breaks. ecDNAs and their corresponding chromosomal scars can form via nonhomologous end joining or microhomology-mediated end joining, but the ecDNA and scar formation processes are distinct. Based on our findings, we establish a mechanistic model of excisional ecDNA formation.

染色体外DNA(ecDNA)上的癌基因扩增是癌症中普遍存在的驱动事件,但我们对ecDNA如何形成的了解却很有限。在这里,我们将基于CRISPR的ecDNA诱导方法与新形成的ecDNA的广泛表征结合起来,研究它们的生物发生过程。我们发现,无论三维基因组背景如何,DNA环化都是高效的,800kb、1 Mb 和 1.8 Mb ecDNA 的形成率都达到或超过了 15%。我们发现非同源末端连接和微同源介导的末端连接都有助于ecDNA的形成,而抑制DNA-PKcs和ATM对ecDNA的形成具有相反的影响。EcDNA和相应的染色体切除疤痕的形成速度明显不同,对DNA-PKcs和ATM抑制的反应也不同。综上所述,我们的研究结果支持蜕变DNA形成模型,在该模型中,双链断裂末端与其合法连接伙伴解离,然后非法末端连接形成蜕变DNA和切除疤痕。

The exponential growth of the cancer neuroscience field has shown that the host's immune, vascular, and nervous systems communicate with and influence each other in the tumor microenvironment, dictating the cancer malignant phenotype. Unraveling the nervous system's contributions toward this phenotype brings us closer to cancer cures. In this review, we summarize the peripheral nervous system's contributions to cancer. We highlight the effects of nerve recruitment and tumor innervation, the neuro-immune axis, glial cell activity, and neural regulation on cancer development and progression. We also discuss harnessing the neural control of peripheral cancers as a potential therapeutic approach in oncology. Significance: The continued and growing interest in cancer neuroscience by the scientific and medical communities reflects the rapidly accumulating interdisciplinary understanding of the nervous system's modulation of immune, vascular, and cancer cells' functions in malignancies. Understanding these regulatory functions can identify targets for intervention that may already be clinically available for other indications. This potential brings great excitement and hope for patients with cancer worldwide.

As we cannot reliably distinguish indolent, low-risk ductal carcinoma in situ (DCIS) from potentially progressive, high-risk DCIS, all women with DCIS diagnosis undergo intensive treatment without any benefit. The PREvent ductal Carcinoma In Situ Invasive Overtreatment Now team was established to unravel DCIS biology and develop new multidisciplinary approaches for accurate risk stratification to tackle the global problem of DCIS overdiagnosis and overtreatment.

Significance: Our work demonstrates that the bidirectional interplay between sympathetic nerves and NGF-expressing CAFs drives colorectal tumorigenesis. This study also offers novel mechanistic insights into catecholamine action in colorectal cancer. Inhibiting the neuro-mesenchymal interaction by TRK blockade could be a potential strategy for treating colorectal cancer.

癌症相关成纤维细胞(CAFs)和神经作为肿瘤微环境的组成部分,已分别被证明可直接促进胃肠道癌症的发生。然而,这些细胞是否相互影响以调控癌症进展仍是未知数。我们发现,在结直肠癌(CRC)中,去甲肾上腺素诱导 CAFs 分泌依赖 ADRB2 的神经生长因子(NGF),这反过来又增加了肿瘤内交感神经的支配和去甲肾上腺素的积累。肾上腺素能刺激通过 ADRA2A/Gi- 介导的是相关蛋白(YAP)激活加速了 CRC 的生长。来自 CAFs 的 NGF 可通过 PI3K/AKT 通路直接促进 CRC 细胞生长。用肌球蛋白受体激酶(Trk)抑制剂治疗小鼠,可减少YAP和AKT的活化以及CRC的进展。在人类 CRC 中,NGF 的高表达与间质样肿瘤亚型和患者生存率低有关。这些发现表明,CAF-神经串联在促进 CRC 进展方面发挥着核心作用。用Trk抑制剂阻断这种前馈循环可能是治疗CRC的一种潜在方法。

The Imaging and Molecular Annotation of Xenografts and Tumors Cancer Grand Challenges team was set up with the objective of developing the "next generation" of pathology and cancer research by using a combination of single-cell and spatial omics tools to produce 3D molecularly annotated maps of tumors. Its activities overlapped, and in some cases catalyzed, a spatial revolution in biology that saw new technologies being deployed to investigate the roles of tumor heterogeneity and of the tumor micro-environment.
