Species of the genus () are phytopathogens of the Brassicaceae family, which includes oilseed rape. The spores of these fungi spread by airborne transmission, infect plants, and cause crop losses. The secondary metabolism of and was studied and compared, with the main focus being on the ability to produce Extracellular Polymeric Substances (EPS). In spite of the 1.5-2-fold faster growth rate of on Czapek-Dox and other screening media, the average yield of EPS in this fungus was only 0.29 g/L, compared to that of (0.43 g/L). In turn, showed a higher capacity to synthesise IAA, i.e., 14 µg/mL, in contrast to <1.5 µg/mL produced by . On the other hand, the strains showed higher β-glucanase activity (350-400 mU/mL), compared to 50-100 mU/mL in . Invertase levels were similar in both species (250 mU/mL). The positive correlation between invertase activity and EPS yield contrasted with the absence of a correlation of EPS with β-glucanase. neither solubilised phosphate nor used proteins from milk. All strains showed the ability to synthesise siderophores on CAS agar. exhibited the highest efficiency of amylolytic and cellulolytic activity.

Benzene degradation under anoxic conditions was first reported more than 25 years ago; however, the activation mechanism in the absence of oxygen remains elusive. Progress has been hindered by the difficulty in cultivating anaerobic benzene-degrading enrichment cultures. Our laboratory has sustained a methanogenic enrichment culture harboring ORM2, a benzene fermenter distinct from any known genus but related to other known or predicted benzene degraders.

The extracellular matrix (ECM) is a complex structure involved in many biological processes with collagen being the most abundant protein. Density of collagen fibers in the matrix is a factor influencing cell motility and migration speed. In cancer, this affects the ability of cells to migrate and invade distant tissues which is relevant for designing new therapies.

Background: Astrocytes are a numerous and diverse glial subtype specialised to carry out distinct roles involving maintaining homeostasis and effective functioning of the nervous system. To do so effectively, they respond to and secrete various proteins. In addition, astrocytes have been linked to Alzheimer's disease (AD), where they are believed to become reactive and contribute to neuroinflammation.

Many cancer cells exhibit increased amounts of paucimannose glycans, which are truncated N-glycan structures rarely found in mammals. Paucimannosidic proteins are proposedly generated within lysosomes and exposed on the cell surface through a yet uncertain mechanism. In this study, we revealed that paucimannosidic proteins are produced by lysosomal glycosidases and secreted via lysosomal exocytosis.

SORL1 (SORLA, LR11) is a large (2214 residue), multi-domain type 1 integral membrane protein that is the product of the SORL1 gene. In neurons, where it is highly expressed, SORL1 functions as both a substrate of and a cargo receptor for the retromer multi protein complex that is a master regulator of protein trafficking out of the early endosome. The SORL1-Vps26b retromer, in particular, is dedicated to the recycling of cell surface proteins, including APP and AMPA receptor subunit GLUA1, back to the plasma membrane.
