Introduction: Owing to its high prevalence, colossal potential of chemoresistance, metastasis, and relapse, breast cancer (BC) is the second leading cause of cancer-related fatalities in women. Several treatments (eg, chemotherapy, surgery, radiations, hormonal therapy, etc.) are conventionally prescribed for the treatment of BC; however, these are associated with serious systemic aftermaths.

In vegetative hyphae, chitin, β-1,3-glucan (laminarin), and a mixed β-1,3-/β-1,4-glucan (lichenin) are the major cell wall polysaccharides. GH72 enzymes have been shown to function as β-1,3-glucanases and glucanosyltransferases and can function in crosslinking β-1,3-glucans together. To characterize the enzymatic activities of the enzymes, we expressed GEL-1 with a HIS6 tag in A chimeric maltose binding protein:GEL-2 was produced in .

The management of wounds infected with drug-resistant bacteria represents a significant challenge to public health globally. Nanotechnology-functionalized photothermal hydrogel with good thermal stability, biocompatibility and tissue adhesion exhibits great potential in treating these infected wounds. Herein, a novel photothermal hydrogel (mCS-Cu-Ser) was prepared through in situ mineralization in the hydrogel networks and ion cross-linking driven by copper ions (∼3 mM).

Chitinase 1 (CHIT1), as a chitin-specific hydrolase, significantly influences the progression of Alzheimer's disease (AD) through microglia-associated inflammation and amyloid beta (Aβ) plaque accumulation. However, the precise mechanism of CHIT1 action in AD remains uncertain. The effects of CHIT1 on cerebral blood flow (CBF), hippocampal volume, and cognitive function were investigated in APP/PS1 mice.
