SRC and TKS5 mediated podosome formation in fibroblasts promotes extracellular matrix invasion and pulmonary fibrosis.

The activation and accumulation of lung fibroblasts resulting in aberrant deposition of extracellular matrix components, is a pathogenic hallmark of Idiopathic Pulmonary Fibrosis, a lethal and incurable disease. In this report, increased expression of TKS5, a scaffold protein essential for the formation of podosomes, was detected in the lung tissue of Idiopathic Pulmonary Fibrosis patients and bleomycin-treated mice. Τhe profibrotic milieu is found to induce TKS5 expression and the formation of prominent podosome rosettes in lung fibroblasts, that are retained ex vivo, culminating in increased extracellular matrix invasion.

Antiproliferative and cytotoxic action of N-(p-coumaroyl) serotonin in lung cancer cells.

Purpose: Lung cancer is among the leading causes of cancer-related cases and cancer-associated deaths. Tumor cells frequently acquire chemoresistance and, due to that, new therapies are always needed in the fight against cancer. Pharmaceutical plants continue to offer novel compounds as anticancer therapies.

N-(p-coumaroyl) serotonin induces cell cycle arrest and apoptosis in breast cancer cells.

Purpose: Breast cancer is the most commonly diagnosed malignancy among women. Breast cancer cells may develop resistance to current chemotherapy, thus new chemotherapeutic agents are urgently needed.

Methods: A major number of drugs with anticancer activity have been isolated from plants.

In Surgical Colon Cancer Patients Extended-Duration Thromboprophylaxis (30 days) with the Highest Dose of Tinzaparin (4,500 IU s.c./q.d.) Normalizes the Postoperative VEGF Levels.

In colon cancer (CC) patients preoperative (pre-op) levels of VEGF-A (VEGF) is a strong predictor for disease recurrence. Elevated postoperative (post-op) VEGF levels could have undesirable effects by enhancing tumor growth and metastasis formation. It has been suggested that thromboprophylaxis with a Low Molecular Weight Heparin (LMWH) in surgical cancer patients, further to thromboembolic protection, may exert some anti-neoplastic properties, as well.
