[en] Yes-associated protein (YAP) is a major downstream molecular of the Hippo pathway, which plays important role in cancer development. Netrin-1 conveys oncogenic activity in many types of malignant tumors. However, the downstream signaling of netrin-1 mediating its oncogenic effects in gastric cancer (GC) is not well defined. Here, we aim to investigate the role of netrin-1 in metastasis potential of GC by regulating YAP. In this study, we showed that netrin-1 inhibition significantly decreased migration and invasion abilities of GC cells, while netrin-1 overexpression effectively reversed this effect. We also demonstrated that netrin-1 upregulated YAP expression via its transmembrane receptor neogenin. Furthermore, our in vitro and in vivo results showed that the effect of netrin-1 on GC cells migration and invasion abilities was regulated by YAP. Collectively, our results defined netrin-1 as a positive regulator of malignant tumor metastasis in GC by activating the YAP signaling, with potential implications for new approaches to GC therapy.

[en] In 63 patients with mammary or bronchial carcinoma, 88 painful bone metastases were randomly irradiated with one of two schedules to find out wether a short treatment would give the same palliative effect as a longer scheme does. After evaluation of the reaction of the pain to the irradiation and assesment of the side effects, it was found that a shorter schedule can be equally effective without an increase in the incidence and degree of side effects

[en] Highlights: • High ZIC5 expression in specimens indicates poor prognosis of HCC patients. • ZIC5 was required in proliferation and tumorigenicity of HCC. • ZIC5 promotes proliferation and tumorigenicity of HCC cells. • ZIC5 promoted growth of HCC in a β-catenin dependant manner. The incidence and mortality of hepatocellular carcinoma (HCC) is high, but the mechanisms underlying the growth and progression of HCC have not been elucidated. Recently, the ZIC family member 5 (ZIC5) is emerging as an oncogene in various types of tumors. However, its expression and biological role in HCC have not been reported. This study first demonstrated that ZIC5 was up-regulated in HCC specimens, and high ZIC5 expression indicated poor prognosis of HCC patients. In addition, over-expressed ZIC5 promoted the proliferation, migration and invasion of HCC cell lines Huh7 and HepG2 in vitro and in vivo, while ZIC5 knockdown achieved the opposite effects. Actually, ZIC5 increased the expression of genes participating in Wnt/β-catenin pathway such as β-catenin and CyclinD1. ZIC5 also promoted β-catenin to enter the nucleus of HCC cells. Furthermore, silencing β-catenin abated the promoting role of ZIC5 in HCC. Overall, this study reveals a novel mechanism of ZIC5/β-catenin that mediates the invasion and metastasis of HCC and ZIC5 serves as a novel indicator for prognosis of HCC patients.

[en] The prevalence of bone metastases from colorectal cancer (CRC) is quite low and the presence of isolated osseous metastases at the time of diagnosis or the onset of bone metastases without other organ involvement during follow-up is even lower. Here, we present an interesting case of diffuse skeletal metastases from CRC in which both the atypical presentation of the metastatic spread and the presence of infective comorbidities created some troubles in getting the final diagnosis

Despite the huge size, there was no hemoptysis due to the walling off effect by the necrotic nodes

[en] Malignancies of the aortic wall represent a rare condition, and only a few reports have covered cases of sarcomas arising at the site of a prosthesis made of Dacron. A coincidence with endovascular repair has only been reported in one case to date. We report a patient with epithelioid angiosarcoma and metastatic disease, which was found in an aneurysmal sac after endovascular aortic repair for abdominal aortic aneurysm.

[en] Highlights: • Different expressed miRNAs and mRNAs were profiled in lowly and highly metastatic SACC cell lines. • Multiple regulatory interactions between miRNAs and mRNAs may contribute to SACC metastasis. • miR-338–5p/3p and their target LAMC2 function on metastasis of multiple types of cancer. Salivary adenoid cystic carcinoma (SACC) is often accompanied with poor prognosis due to local recurrence, distant metastasis, and perineural invasion. The mechanism involved in SACC metastasis is not yet fully understood. In this study, we profiled the expression of messenger RNA (mRNA) and microRNA (miRNA) in a SACC cell line, ACC-2, and a highly metastatic SACC cell line, ACC-M, using high-throughput sequencing. We discovered that: (1) differentially expressed (DE) mRNAs and DE miRNAs are potentially involved in SACC metastasis; (2) multiple regulatory interactions between DE miRNAs and DE mRNAs exist; and (3) miR-338–5p/3p target LAMC2 to impair motility and invasion of ACC-M and MDA-MB-231 cells. In conclusion, our study integrated the regulatory effects of miRNAs and mRNAs on SACC metastasis and provided a potential application for miRNAs in future therapeutic intervention.
