Missed Druggable Cancer Hallmark: Cancer-Stroma Symbiotic Crosstalk as Paradigm and Hypothesis for Cancer Therapy.

Summary of "Missed Druggable Cancer Hallmark: Cancer-Stroma Symbiotic Crosstalk as Paradigm and Hypothesis for Cancer Therapy."

During tumor evolution, cancer cells use the tumor-stroma crosstalk to reorganize the microenvironment for maximum robustness of the tumor. The success of immune checkpoint therapy foretells a new cancer therapy paradigm: an effective cancer treatment should not aim to influence the individual components of super complex intracellular interactomes (molecular targeting), but try to disrupt the intercellular interactions between cancer and stromal cells, thus breaking the tumor as a whole. Arguments are provided in favor of a hypothesis that such interactions include formation of synapse-like structures (interfaces) where the interacting cells are located at a distance of ∼10-15 nm. Within these interfaces, molecules initiating and strengthening the interaction are organized, and allow optimum cross-signaling; a very confined intercellular space facilitates the concentration of secreted cytokines, enhancing the paracrine cross-communication. These features of tumors form a druggable cancer hallmark the tumor-stroma symbiotic crosstalk-which represents a new target for efficient cancer drug discovery.

Reflections on depletion of tumor stroma in pancreatic cancer.

Pancreatic cancer characteristically has an extremely dense stroma, which facilitates chemoresistance by creating physical and biological barriers to therapeutic agents. Thus, stroma-depleting agents ...

Overexpression of miR‑221 and miR‑222 in the cancer stroma is associated with malignant potential in colorectal cancer.

The cancer stroma is important in cancer development, however, whether the aberrant expression of microRNAs (miRNAs) in the cancer stroma is associated with cancer progression remains to be fully eluc...

Mesenchymal stem cells: Cancer promoting effects or tumor suppression - A current overview.

The multimodal treatment of cancer deals with cancer cells as well as with the cancer surrounding stroma. This stroma contains non-malignant cells like fibroblasts, immune cells as well as mesenchymal...

Topotecan induces apoptosis via ASCT2 mediated oxidative stress in gastric cancer.

Topotecan (TPT) is a Topo I inhibitor and shows obvious anti-cancer effects on gastric cancer. Cancer cells reprogram their metabolic pathways to increase nutrients uptake, which has already been a ha...

Pancreatic cancer microenvironment: a current dilemma.

Pancreatic cancer is one of the leading causes of cancer-related death in the United States and survival outcomes remain dismal despite significant advances in molecular diagnostics and therapeutics i...

Established Lung Cancer Cell Line and Stroma Cell From Surgical Tissue

Try to find lung cancer stem cells from primary culture of routine surgical resection of lung cancer tissue including cancer cells and stroma cells, then characterization the established c...

Symbiotics to Prevent Postoperative Infection in Colorectal Cancer

This is a double blind randomized trial in which patients with colorectal cancer undergoing surgery will be selected to receive either a symbiotic formulation or placebo. The researchers w...

Impact of Symbiotic Administration on Intestinal Function of Head and Neck Patients Surgically Treated

The purpose of this study is to determine whether the symbiotic use in patients with head and neck cancer impact on intestinal function after surgical treatment.

Ploidy and Stroma in Early Rectal Cancer

Early rectal cancer can be removed by minimally-invasive surgery, and the standard pathological assessment of the removed tumour gives valuable information about how advanced the tumour is...

Assessment of the Symbiotic Fermented Milk in Patients With Irritable Bowel Syndrome

This study evaluates the effect of a symbiotic fermented milk on health-related quality of life and irritable bowel syndrome (IBS) symptoms in patients with constipation-predominant IBS.

Medical and Biotech [MESH] Definitions

A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.

That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.

A voluntary organization concerned with the prevention and treatment of cancer through education and research.

A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
