The senescence-associated secretory phenotype in ovarian cancer dissemination.

Ovarian cancer is a highly aggressive disease with poor survival rates in part due to diagnosis after dissemination throughout the peritoneal cavity. It is well-known that inflammatory signals affect ovarian cancer dissemination. Inflammation is a hallmark of cellular senescence, a stable cell cycle arrest induced by a variety of stimuli including many of the therapies used to treat patients with ovarian cancer.

Methods to measure calcitonin receptor activity, up-regulated in cell stress, apoptosis and autophagy.

The expression of the calcitonin receptor (CT Receptor) is widespread throughout the life cycle of mammals and in many diseases, and in these contexts the functions of the common isoforms is largely unknown. The relatively recent development of anti-CT Receptor antibodies that bind separate epitopes on the CT Receptor and CT Receptor isoforms has advanced our knowledge and understanding of these events. CT Receptor at the protein level is upregulated in programmed cell death including apoptosis (as described in a previous publication) and autophagy, which is discussed in our upcoming, unpublished review.

Building the case for the calcitonin receptor as a viable target for the treatment of glioblastoma.

Researchers are actively seeking novel targeted therapies for the brain tumour glioblastoma (GBM) as the mean survival is less than 15 months. Here we discuss the proposal that the calcitonin receptor (CT Receptor), expressed in 76-86% of patient biopsies, is expressed by both malignant glioma cells and putative glioma stem cells (GSCs), and therefore represents a potential therapeutic target. Forty-two per cent (42%) of high-grade glioma (HGG; representative of GSCs) cell lines express CT Receptor protein.

GPR43 regulates sodium butyrate-induced angiogenesis and matrix remodeling.

Butyrate is a short-chain fatty acid (SCFA) derived from microbiota and is involved in a range of cell processes in a concentration-dependent manner. Low concentrations of sodium butyrate (NaBu) were shown to be proangiogenic. However, the mechanisms associated with these effects are not yet fully known.

Novel synthetic chalcones induces apoptosis in human glioblastoma cells.

Glioblastoma multiforme is the main and most frequent tumor in adults' central nervous system. With a survival average of 5% two years after diagnosis, this type of cancer is a main health problem. Substances like the chalcones have been tested in order to develop new treatments.

Impairment of stress granule assembly via inhibition of the eIF2alpha phosphorylation sensitizes glioma cells to chemotherapeutic agents.

Malignant gliomas are a lethal type of brain tumors that poorly respond to chemotherapeutic drugs. Several therapy resistance mechanisms have been characterized. However, the response to stress through mRNA translational control has not been evaluated for this type of tumor.
