Cancer control: Non-DNA changes induce metabolism variations in hepatocellular carcinomas
Mechanisms underlying metabolic variations in hepatocellular carcinoma (HCC), a fast growing and invasive cancer, remain unclear. Now, researchers from Fudan University, China identified signatures of ''m6A,'' the most abundant ''post-transcriptional RNA modification,'' that segregate HCC into sub-types with distinct metabolic characteristics. They have also developed a novel m6A score that can quantify such modifications and aid risk assessment, prediction of prognosis, and response to treatment in patients with HCC. (2021-02-22)

BU researchers identify promising therapeutic agent against melanoma
There have been great advances in treating melanoma over the past five years, however, even with these treatments many patients quickly develop drug resistance and die from their disease. A new study from Boston University School of Medicine (BUSM) has discovered that a drug (YK-4-279) that was previously created to target one specific type of protein has much broader use against a family of proteins that act to promote melanoma. (2021-02-01)

Novel therapy-resistance mechanism promoting the growth of breast cancer brain metastasis
SORLA is a protein trafficking receptor that has been mainly studied in neurons, but it also plays a role in cancer cells. Professor Johanna Ivaska's research group at Turku Bioscience observed that SORLA functionally contributes to the most reported therapy-resistant mechanism by which the cell-surface receptor HER3 counteracts HER2 targeting therapy in HER2-positive cancers. Removing SORLA from cancer cells sensitized anti-HER2 resistant breast cancer brain metastasis to targeted therapy. (2021-01-29)

Fighting cancer from a chair
Cisplatin has been used to treat cancer since the 1970s. Since then, many other platinum-containing cytostatic drugs have been developed, such as triplatinNC, a highly charged complex that contains three ligand-bridged platinum atoms. Unlike cisplatin, this drug also directly inhibits metastasis. The reason for this seems to be modulation of the geometry of a sugar component of heparan sulfate, an important component of the extracellular matrix, reports a research team in the journal Angewandte Chemie. (2021-01-25)

When -- not what -- obese mice ate reduced breast cancer risk
University of California San Diego School of Medicine and Moores Cancer Center researchers report that intermittent fasting reduced breast cancer risk in obese mice. (2021-01-25)

A mathematical study describes how metastasis starts
A scientific study carried out by the Universidad Carlos III de Madrid (UC3M) and the Universidad Complutense de Madrid (UCM) has produced a mathematical description of the way in which a tumor invades the epithelial cells and automatically quantifies the progression of the tumor and the remaining cell islands after its progression. The model developed by these researchers could be used to better understand the biophysical characteristics of the cells involved when developing new treatments for wound healing, organ regeneration, or cancer progression. (2021-01-18)

Cancer models created by mechanical engineers offer new insight into tumor growth
In research published today in Integrative Biology, a team of engineers from Rensselaer developed an in vitro -- in the lab -- lymphatic vessel model to study the growth of tumor emboli, collections of tumor cells within vessels that are often associated with increased metastasis and tumor recurrence. (2021-01-14)

Texas A&M research explores how melanoma grows and spreads
The first step in treating cancer is understanding how it starts, grows and spreads throughout the body. A relatively new cancer research approach is the study of metabolites, the products of different steps in cancer cell metabolism, and how those substances interact. (2021-01-12)

It provides a novel and noninvasive approach for stomach cancer patients and may inform individualized surgical management of stomach cancer. (2021-01-07)

Anticoagulants reduce the number of brain metastases in mice
Brain metastases can only develop if cancer cells exit the capillaries and enter into the brain tissue. To facilitate this step, cancer cells influence blood clotting, as Heidelberg scientists have now been able to show in mice. The cancer cells actively promote the formation of clots, which helps them to arrest in the brain capillaries and then penetrate through the vessel wall. Drugs that inhibit thrombin were able to reduce the number of brain metastases. (2021-01-05)

Discovery about how cancer cells evade immune defenses inspires new treatment approach
Researchers at Memorial Sloan Kettering have learned how chromosomal instability allows cancer cells to avoid immune defenses and metastasize (spread). The discovery opens up potential new avenues for treatment. (2020-12-28)

Hinder handing the message -- stopping tumors from creating new blood vessels
Researchers from Tokyo Medical and Dental University (TMDU) have found that vasohibin-1 (VASH1), a protein known to prevent the formation of new blood vessels, acts by changing the conditions of microtubules which bring blocking the certain signal from outside through encumbering transport of its message to the inner of cell. The unique function of this protein can inhibit tumor cells from spreading throughout the body, making it a notable finding for cancer therapeutic research. (2020-12-14)

Omitting radiation therapy after breast-conserving surgery may not impact 10-year survival rates for older patients with HR-positive breast cancer
Older patients with hormone receptor-positive breast cancer who did not receive radiation therapy after breast-conserving surgery had higher rates of local recurrence but similar 10-year survival rates when compared to patients who received postoperative radiation therapy, according to updated 10-year data from the PRIME II study, presented at the 2020 San Antonio Breast Cancer Symposium. (2020-12-09)

Researchers discover key driver of the spread of cancer to the brain
Approximately 200,000 cancer patients are diagnosed with brain metastases each year, yet few treatment options exist because the mechanisms that allow cancer to spread to the brain remain unclear. However, a study recently published in the journal Cancer Cell by VCU Massey Cancer Center scientist Suyun Huang, M.D., Ph.D., offers hope for the development of future therapies by showing how a poorly understood gene known as YTHDF3 plays a significant role in the process. (2020-12-08)

β-AR agonist therapy puts the brakes on oral cancer progression
Oral cancer has a high mortality rate that is mainly attributed to metastasis. Researchers from Tokyo Medical and Dental University (TMDU) screened a panel of small chemical compounds for their ability to inhibit metastasis in oral cancer, identifying β2?AR-agonist isoxsuprine as a potential candidate. Treatment of various oral cancer cells with isoxsuprine suppressed their motility, while tumor size was significantly decreased in isoxsuprine-treated mice, suggesting that β-AR-agonist therapy could be an effective new treatment for oral cancer. (2020-12-03)

Watch immune cells dig tunnels in tissues
White blood cells called cytotoxic T lymphocytes (CTLs) dig tunnels in tissues, potentially allowing other CTLs to quickly reach infected cells and tumor cells, researchers report December 1st in Biophysical Journal. The results show that some CTLs move slowly as they create channels through the extracellular matrix (ECM) - a major component of tissues. Afterward, other CTLs move quickly through the channels, presumably to efficiently search for and eliminate target cells. (2020-12-01)

Breast cancer discovery could help stop disease's deadly spread
Researchers have identified a gene responsible for the spread of triple-negative breast cancer to other parts of the body and developed a potential way to stop it. (2020-11-20)

Ovarian cancer cells cooperate to metastasize
In a study on human ovarian cancer cells in mice, Harvard Medical School researchers discovered a transient, cooperative interaction between cell subpopulations that allows otherwise nonmetastatic tumor cells to become aggressive and spread. (2020-11-18)

Cancer metastasis: From problem to opportunity
When cancer metastasizes, it often ends up in the lungs, where the new tumors unleash a cascade of chemical cues that thwart the body's immune response. A team of researchers from the Wyss Institute has created a new approach that attacks metastasis itself by using red blood cells as couriers to deliver nanoparticles filled with immune-cell-attracting chemicals. This approach halted lung tumor growth in mice with metastatic breast cancer and protected the animals against future cancer recurrences.  (2020-11-16)

Brain metastases cause severe brain damage that can be inhibited by treatment
By using a specific treatment to override this activation, the researchers were able to return cerebrovascular flow to healthy levels. This improvement in blood flow around the metastases can limit the neurological deterioration associated with the progression of this disease and improve the otherwise poor life expectancy of these patients. (2020-11-12)

Shedding new light on the origin of metastases
Before an effective treatment can be devised, we have to be able to understand the specific effect of an anti-cancer substance on the cell type that produces metastases in the cellular heterogeneity of tumours. A team from the University of Geneva used spiked-scRNAseq that links the transcriptomic to single cell metastatic phenotypes of colon cancer tumour cells. The importance of the VSIG1 gene involved in intercellular interactions has been identified: it prevents metastases. (2020-11-10)

The cover for Issue 43 of Oncotarget features Figure 6, ''(A) Following the experimental protocol of Franzetti et al. [11] A673-shA1c cells ?/+ Dox (EWS/Fli1high/EWS/Fli1low) were injected into the tail vein, and metastases were allowed to form in the absence of further Dox treatment (to allow recovery of cell growth in EWS/Fli1low cells),'' (2020-10-27)

How to prevent the spread of tumor cells via the lymph vessels
Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg identified a new way to block the dangerous spread of tumor cells via lymphatic vessels. They discovered that an antibody against a signaling molecule of the vascular system causes the lymphatic vessels in the tumor to die, suppresses metastasis and thus prolongs the survival of the mice. (2020-10-26)

MFS Is a strong surrogate endpoint for OS for men receiving salvage RT for recurrent prostate cancer
An analysis of the phase III NRG Oncology clinical trial RTOG 9601 on men receiving salvage radiotherapy (SRT) following prostatectomy for recurrent prostate cancer indicated that, while biochemical failure (BF) was not a strong surrogate endpoint to determine overall survival (OS), metastasis-free survival (MFS) was in this patient population. (2020-10-26)

New technology tracks role of macrophages in cancer spread
A Morgridge imaging study of macrophages -- immune cells that are important to human health, but paradoxically can help some cancers grow and spread -- is offering better ways to understand these cells and target them with immunotherapies. (2020-10-26)

Effectiveness of gemcitabine & daily RT for bladder preservation in muscle-invasive bladder cancer
Bladder preservation with trimodality therapy can be a safe and effective alternative to cystectomy for selected patients with muscle-invasive bladder cancer. The phase II NRG Oncology NRG-RTOG 0712 trial evaluated two regimens. One was the prior RTOG standard using 5-flourouracil and cisplatin with twice daily radiation (FCT), and the other a regimen of gemcitabine and daily radiation (GD) which had demonstrated efficacy in single institution clinical trials. (2020-10-26)
