Marine Cellulases and their Biotechnological Significance from Industrial Perspectives.

Marine microorganisms represent virtually unlimited sources of novel biological compounds and can survive extreme conditions. Cellulases, a group of enzymes that are able to degrade cellulosic materials, are in high demand in various industrial and biotechnological applications, such as in the medical and pharmaceutical industries, food, fuel, agriculture, and single-cell protein, and as probiotics in aquaculture. The cellulosic biopolymer is a renewable resource and is a linearly arranged polysaccharide of glucose, with repeating units of disaccharide connected via β-1,4-glycosidic bonds, which are broken down by cellulase.

Altered Expression of MBNL Family of Alternative Splicing Factors in Colorectal Cancer.

Background/aim: Colorectal cancer is currently the third leading cause of cancer-related deaths and recently, alternative splicing has risen as its important regulator and potential treatment target. In the present study, we analyzed gene expression of the MBNL family of regulators of alternative splicing in various stages of colorectal cancer development, together with the MBNL-target splicing events in FOXP1 and EPB41L3 genes and tumor-related CD44 variants.

Materials And Methods: Samples of tumor tissue and non-malignant mucosa from 108 patients were collected.

In vitro study of the scolicidal effects of Echinometra mathaei spine and shell extracts on hydatid cyst protoscolices.

Hydatid cyst is a zoonotic parasitic infection caused by the tapeworm Echinococcus granulosus. Such infections are of considerable public health and economic concern, and new effective treatments are intensely sought. Sea urchin (Salmacis virgulata) shell extracts have potent antimicrobial and antioxidant activity, and spines of several species of echinoderms also show antimicrobial activity.
