Controlling secretion to limit chemoresistance [PDF]
The tumor microenvironment influences cancer progression and therapy outcome by mechanisms not yet fully understood. In this issue, Bent et al. (2016) show how chemotherapy causes endothelial senescence.

NGR‐Modified CAF‐Derived exos Targeting Tumor Vasculature to Induce Ferroptosis and Overcome Chemoresistance in Osteosarcoma [PDF]
Osteosarcoma (OS) chemoresistance presents a significant clinical challenge. This study aims to investigate the potential of using tumor vascular‐targeting peptide NGR‐modified cancer‐associated fibroblasts (CAFs)‐derived exosomes (exos) to deliver ...

Mitochondrial determinants of chemoresistance [PDF]
Chemoresistance constitute nowadays the major contributor to therapy failure in most cancers. There are main factors that mitigate cell response to therapy, such as target organ, inherent sensitivity to the administered compound, its metabolism, drug efflux and influx or alterations on specific cellular targets, among others. We now know that intrinsic

Exosomal miR-331 from Chemoresistant Osteosarcoma Cells induced Chemoresistance through Autophagy [PDF]
Abstract BackgroundOsteosarcoma (OS) is a highly malignant tumor. Improving chemotherapeutic resistance is very important to improve the survival rate of OS. Exosomes and microRNAs (MiRNA) play important roles in the mechanism of chemotherapeutic resistance transmission. More and more researches focus the mechanism of miRNAs carried by exosomes

Clusterin and Chemoresistance [PDF]
Resistance to anticancer agents is one of the primary impediments to effective cancer therapy. Chemoresistance occurs not only to clinically established therapeutic agents but also to novel targeted therapeutics. Both intrinsic and acquired mechanisms have been implicated in drug resistance but it remains controversial which mechanisms are responsible ...

Genome expression analysis by suppression subtractive hybridization identified overexpression of Humanin, a target gene in gastric cancer chemoresistance [PDF]
Background: In cancer cells, apoptosis is an important mechanism that influences the outcome of chemotherapy and the development of chemoresistance.

Apoptosis and melanoma chemoresistance [PDF]
Melanoma is the most aggressive form of skin cancer and is notoriously resistant to all current modalities of cancer therapy. A large set of genetic, functional and biochemical studies suggest that melanoma cells become 'bullet proof' against a variety of chemotherapeutic drugs by exploiting their intrinsic resistance to apoptosis and by reprogramming ...

Loss of histone macroH2A1 in hepatocellular carcinoma cells promotes paracrine-mediated chemoresistance and CD4+CD25+FoxP3+ regulatory T cells activation [PDF]
Rationale: Loss of histone macroH2A1 induces appearance of cancer stem cells (CSCs)-like cells in hepatocellular carcinoma (HCC). How CSCs interact with the tumor microenvironment and the adaptive immune system is unclear. Methods: We screened aggressive

Identification of multidrug chemoresistant genes in head and neck squamous cell carcinoma cells
Multidrug resistance renders treatment failure in a large proportion of head and neck squamous cell carcinoma (HNSCC) patients that require multimodal therapy involving chemotherapy in conjunction with surgery and/or radiotherapy.

Chemoresistance in Pancreatic Cancer [PDF]
Pancreatic ductal adenocarcinoma (PDAC), generally known as pancreatic cancer (PC), ranks the fourth leading cause of cancer-related deaths in the western world. While the incidence of pancreatic cancer is displaying a rising tendency every year, the mortality rate has not decreased significantly because of late diagnosis, early metastasis, and limited
