Integrated analysis of long noncoding RNA expression profiles in lymph node metastasis of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide, and metastasis of HCC is the leading cause of poor prognosis. Among all the extrahepatic metastases, lymph node metastasis (LNM) is common, second only to lung metastasis. However, the pathogenesis of HCC LNM remains largely unknown.

Tumor-to-lesion metastasis: a case report of carcinoma metastasis to multiple sclerosis lesion.

The term of "tumor-to-lesion metastasis" is an extension of "tumor-to-tumor metastasis", which is a rare but well-documented phenomenon. Tumor metastasis to the meninges and/or central nervous system (CNS) is rare in patents with multiple sclerosis (MS), although MS lesions bear many similarities to the primary tumor microenvironment and the metastatic niche. We present the first case of malignant tumor metastasis to MS lesions with immunophenotyping of inflammatory cells in the metastatic foci.

miRNAs in bone metastasis.

Bone metastasis is one of the most common forms of metastasis from a number of different primary carcinomas. MicroRNAs (miRNAs) are short, endogenous RNAs that negatively regulate gene expression to control essential pathways, including those involved in bone organogenesis and homeostasis. As these pathways are often hijacked during bone metastasis, it is not surprising that miRNAs can also influence bone metastasis formation. Areas covered: In this review, we first summarize the major signalling pathways i...

Acrocutaneous metastasis - A rare presentation.

Cutaneous metastasis from head and neck cancer is uncommon and it is seen from laryngeal cancer. Acrocutaneous metastasis from the base of tongue is relatively rare.

Dinitrosopiperazine-decreased PKP3 through upregulating miR-149 participates in nasopharyngeal carcinoma metastasis.

Nasopharyngeal carcinoma (NPC) has a high metastatic clinicopathological feature. As a carcinogen factor, N,N'-dinitrosopiperazine (DNP) is involved in NPC metastasis, but its precise mechanism has not been fully elucidated. Herein, we showed that DNP promotes NPC metastasis through upregulating miR-149. DNP was found to decrease Plakophilin3 (PKP3) expression, further DNP-decreased PKP3 was verified to be through upregulating miR-149. We also found that DNP induced proliferation, adhesion, migration and in...

Wnt signaling in bone metastasis: mechanisms and therapeutic opportunities.

Bone metastasis frequently occurs in advanced cancer patients, who will develop osteogenic/osteolytic bone lesions in the late stage of the disease. Wnt signaling pathway, which is mainly grouped into the β-catenin dependent pathway and β-catenin independent pathway, is a well-organized cascade that has been reported to play important roles in a variety of physiological and pathological conditions, including bone metastasis. Regulation of Wnt signaling in bone metastasis involves multiple stages, includin...

Imaging Brain Metastasis Patients With 18F-(2S,4R)-4-Fluoroglutamine.

There is a need for an alternative PET probe, which does not show normal brain tissue uptake in the evaluation of metastasis to the brain. Therefore, we investigate the feasibility of F-labeled glutamine analog, F-(2S,4R)-4-fluoroglutamine (F-FGln), as a new metabolic probe to detect brain metastasis.

PIK3R3 Promotes Metastasis of Pancreatic Cancer via ZEB1 Induced Epithelial-Mesenchymal Transition.

PIK3R3 is a regulatory subunit of phosphatidylinositol 3-kinase (PI3K) which plays an essential role in the metastasis of several types of cancer. However, whether PIK3R3 can promote the metastasis of pancreatic cancer (PC) is still unclear. In this study, we characterized the role of PIK3R3 in metastasis of PC and underlying potential mechanisms.

Forkhead box C1 promotes colorectal cancer metastasis through transactivating ITGA7 and FGFR4 expression.

Metastatic colorectal cancer (CRC) is one of the most common causes of cancer death worldwide; however, the molecular mechanism underlying CRC metastasis remains unknown. Using an integrated approach, we identified forkhead box C1 (FOXC1) as a novel regulator of CRC metastasis. Elevated expression of FOXC1 is significantly correlated with metastasis, recurrence and reduced survival. FOXC1 overexpression promotes CRC invasion and lung metastasis, whereas FOXC1 knockdown has the opposite effect. In addition, ...

Aberrant expression of CITED2 promotes prostate cancer metastasis by activating the nucleolin-AKT pathway.

Despite many efforts to develop hormone therapy and chemotherapy, no effective strategy to suppress prostate cancer metastasis has been established because the metastasis is not well understood. We here investigate a role of CBP/p300-interacting transactivator with E/D-rich carboxy-terminal domain-2 (CITED2) in prostate cancer metastasis. CITED2 is highly expressed in metastatic prostate cancer, and its expression is correlated with poor survival. The CITED2 gene is highly activated by ETS-related gene that...

Mechanisms and context underlying the role of autophagy in cancer metastasis.

Macroautophagy/autophagy is a fundamental cellular degradation mechanism that maintains cell homeostasis, regulates cell signaling, and promotes cell survival. Its role in promoting tumor cell survival in stress conditions is well characterized, and makes autophagy an attractive target for cancer therapy. Emerging research indicates that autophagy also influences cancer metastasis, which is the primary cause of cancer-associated mortality. However, data demonstrate that the regulatory role of autophagy in m...

BRMS1L suppresses ovarian cancer metastasis via inhibition of the β-catenin-wnt pathway.

A low level of breast cancer metastasis suppressor 1-like (BRMS1L) has been implicated in tumour metastasis involving breast cancer and other cancers. It remains unclear whether BRMS1L is involved in epithelial ovarian cancer (EOC) metastasis and what the molecular mechanism of BRMS1L is in suppressing EOC metastasis. In this study, we examined the mRNA expression and protein level of BRMS1L by screening EOC patients. Our results show that BRMS1L expression is downregulated in EOC patients compared to that ...

Analysis of metastasis associated signal regulatory network in colorectal cancer.

Metastasis is a key factor that affects the survival and prognosis of colorectal cancer patients. To elucidate molecular mechanism associated with the metastasis of colorectal cancer, genes related to the metastasis time of colorectal cancer were screened. Then, a network was constructed with this genes. Data was obtained from colorectal cancer expression profile. Molecular mechanism elucidated the time of tumor metastasis and the expression of genes related to colorectal cancer. We found that metastasis-pr...

hsa‑miR‑24 suppresses metastasis in nasopharyngeal carcinoma by regulating the c‑Myc/epithelial‑mesenchymal transition axis.

Distant metastasis is the major contributor to treatment failure and mortality in patients with nasopharyngeal carcinoma (NPC). The lack of effective treatment strategies for metastatic NPC is the major cause for the low survival rate. Therefore, it is crucial to understand the molecular mechanisms underlying NPC metastasis and to identify potential biomarkers for targeted therapy. MicroRNA (miRNAs or miRs) have been shown to play an important role in tumorigenesis and metastasis. In the present study, we a...

Regulatory mechanisms of miR-145 expression and the importance of its function in cancer metastasis.

MicroRNAs are post-transcriptional mediators of gene expression and regulation, which play influential roles in tumorigenesis and cancer metastasis. The expression of tumor suppressor miR-145 is reduced in various cancer cell lines, containing both solid tumors and blood malignancies. However, the responsible mechanisms of its down-regulation are a complicated network. miR-145 is potentially able to inhbit tumor cell metastasis by targeting of multiple oncogenes, including MUC1, FSCN1, Vimentin, Cadherin, F...

Dietary regulation of metastasis.

The impact of diet and associated lifestyle choices on the risk of developing cancer is well established. However, whether these parameters also affect cancer recurrence and survival is less well investigated. Virtually nothing is known about the impact of diet on the development of metastases. It is therefore significant that a study in this issue of Clinical and experimental metastasis reports that breast cancer-bearing mice fed on a diet rich in long-chain omega-3 fatty acids had a lower incidence of met...

Diffuse hepatic epithelioid hemangioendothelioma with multiple splenic metastasis and delayed multifocal bone metastasis after liver transplantation on FDG PET/CT images: A case report.

Malignant hepatic epithelioid hemangioendotheliom (HEH) is a rare vascular tumor of endothelial origin, with multiple metastases to the spleen. This report describes a diffuse HEH with splenic metastasis on 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) images and delayed mutifocal bone metastasis after liver transplantation (LTx).

Validity of a Recently-Proposed Prognostic Grading Index, Brain Metastasis Velocity, for Brain Metastasis Patients Undergoing Multiple Radiosurgical Procedures.

This study, based on our brain metastasis (BM) patients undergoing multiple stereotactic radiosurgery (SRS) procedures, aimed to validate whether the recently-proposed prognostic grading system, brain metastasis velocity (BMV, scoring the cumulative number of new BMs that developed after the first SRS divided by time [years] since the initial SRS), is generally applicable. Patients are categorized into three classes by their BMV scores, i.e., ≤3, 4-13 and ≥14.

Asparagine and Glutamine: Co-conspirators Fueling Metastasis.

Cancer cells frequently hijack normal metabolic pathways to promote their growth and metastasis. Two recent papers by Knott et al. (2018) and Pavlova et al. (2018) demonstrate that asparagine and glutamine work in concert to drive tumor growth and metastasis through modulation of cell survival, growth, and EMT regulatory pathways.

MiR-26a-5p potentiates metastasis of human lung cancer cells by regulating ITGβ8- JAK2/STAT3 axis.

Most lung cancer patients die of metastasis. Recent studies have indicated that dysregulated microRNAs (miRNAs) are involved not only in tumorigenesis, but also in metastasis. In the present study, we found that over-expression of miR-26a-5p potentiated the migration and invasion of lung cancer cells evidenced by wound healing assay and transwell assay, and metastasis-related genes MMP-9 and CD44 were up-regulated. We identified integrin-beta8 (ITGβ8) as a novel target of miR-26a, and ITGβ8 expression was...
