BIOMIMESYS® Oncology is a relevant hydroscaffold for cancer-related in vitro studies

BIOMIMESYS® Oncology is mostly composed of hyaluronic acid (HA), biofunctionnalized with undenaturated collagen I. HA, by interacting with its binding proteins (CD44, RHAMM, ICAM-1), is an active participant in inflammatory, angiogenic, fibrotic and cancer-promoting processes (Figure 1). We are currently looking at the effect of different elastic moduli of BIOMIMESYS® Read more…

Influence of the extracellular matrix on cancer cell proliferation and migration

Extracellular matrix (ECM) is known to have an influence on physiological processes and on tumour progression: ECM properties (composition, stiffness) modulate cell proliferation, migration, invasion and epithelial-to-mesenchymal transition (EMT). For example, EMT is inhibited by laminin-rich environment whereas it is promoted in fibronectin-rich ECM (Chen et al 2013. Differentiation 86, Read more…

An explanation of assymetric distribution of melanin in the epidermis !

The skin performs important function, including sun protection. Melanin distribution in the epidermis plays a role in photoprotection. Solar radiations induced epidermal DNA damages, mostly in the basal layer, and is an established caused of keratinocytes cancers. Melanin distribution in human epidermis is essentialy located in the basal layer. However, Read more…

P. acnes inhibits human melanocytes survival after UVB radiation which could prevent melanoma-genesis causes by DNA damage

Melanoma is a type of skin cancer that develops from cells called melanocytes, is one of the fastest-growing and deadliest cancer in the world. It usually caused by DNA damage resulting from exposure to ultraviolet (UV) light from the sun. P. acnes is a ubiquitous gram-positive anaerobic bacterium present in Read more…

A representative hematoxylin and eosin staining of UV-induced skin tumor or skin obtained from SKH-1 mice colonized by S. epidermidis 1457 or MO34, respectively, treated with UV-B for 12 weeks.

Could skin microbiota reduce cancer risk?

Researchers from the Department of Dermatology of the University of California have a commensal strain of Staphylococcus epidermidis that protects against skin neoplasia. This strain produces 6-N-hydroxyaminopurine (6-HAP), a molecule that inhibits DNA polymerase activity. Mice colonized with this strain have a reduced incidence of ultraviolet-induced tumors compared to control mice (colonized with Read more…
