Aim: This study aims to investigate the possible effects of aqueous Echinacea (E. Purpurea, whole plant) extract on Adenosine deaminase (ADA) activity in cancerous and non-cancerous human gastric and colon tissues. Materials and Methods: Thirty three cancerous and 33 non-cancerous human gastric tissues, and 25 cancerous and non-cancerous human colon tissues removed by surgical operations were s...

Genetic instability promotes cancer progression (by increasing the probability of cancerous mutations) as well as hinders it (by imposing a higher cell death rate for cells susceptible to cancerous mutation). With the loss of tumor suppressor gene function known to be responsible for a high percentage of breast and colorectal cancer (and a good fraction of lung cancer and other types as well), ...

background: trace elements play an important role in a number of biological processes. astaxanthin (asx), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. this work intended to understand the effect of astaxanthin in breast cancer (invasive ductal carcinoma, idc) by using micro-pixe method. for this aim the concentration of tr...

BACKGROUND Natural products isolated from marine environments are well known for their pharmacodynamic potential in diverse disease treatments, such as for cancer or inflammatory conditions. Sea cucumbers are marine animals of the phylum Echinoderm and the class Holothuroidea, with leathery skin and gelatinous bodies. Sponges are important components of Persian Gulf animal communities, and the ...

BACKGROUND Aquaporin 5 (AQP5), a member of the aquaporin family of transmembrane channel proteins, is involved in water transport and cellular proliferation in various tumors. The objective of this study was to determine cellular localization of aquaporin 5 (AQP5) in the ovarian tumors of chicken, a preclinical model for human ovarian tumor and to determine if AQP5 mRNA and protein expression l...

Demonstrated a reliable distinction in the emission and circular dichroism spectral features of TO dye, on binding to DNAs from non-cancerous cancerous tissues, which offers label-free optical method for diagnosis cancer tissues.

Computational and experimental evidence has revealed that cancerous cells express transcript variants that are abnormally spliced, suggesting that mRNAs are more frequently alternatively spliced in cancerous tissues than in normal ones. We show that cancerous tissues exhibit lower levels of alternative splicing than do normal tissues. Moreover, we found that the distribution of types of alterna...
