Sixteen convolvulaceous glycolipids selected from the tricolorin (1 - 7) and orizabin (8 - 16) series, proved to be strong in vitro inhibitors of the enzyme that catalyzes the synthesis of 1,3-beta-D-glucan, a major polymer of fungal cell-walls. Results provide an insight into function of the specific structures of these complex macrocyclic lactones as inhibitors of the 1,3-beta-D-glucan synthase and open the possibility of using these compounds as starting points for the development of antifungal agents that act by inhibiting fungal cell-wall synthesis.

Neuropeptide Y (NPY) and the voltage-gated potassium channel Kv1.3 are closely associated with breast cancer progression and apoptosis regulation, respectively. NPY receptors (NPYRs), which are overexpressed in breast tumors, contribute to tumor growth, migration, and angiogenesis.

To evaluate the expression of hsa_circ_0077007 in the serum of colorectal cancer (CRC) patients and offer a foundational theory for the prognosis of CRC. The present study focuses on investigating the biological function and therapeutic target of hsa_circ_0077007 in colorectal cancer CRC. Retrieve the GEO database and use the GEO2R tool to analyze the GSE dataset (GSE223001 and GSE159669) to obtain aberrantly expressed circRNAs.

Colorectal cancer (CRC) is one of the most common and lethal malignancies worldwide, with treatment failure often attributed to chemoresistance and evasion of apoptosis. Cathayanon E (CE), a natural chalcone derivative isolated from Morus alba, has shown anticancer potential, but its role and mechanism in CRC remain largely unexplored. In this study, CE significantly inhibited CRC cell proliferation and induced apoptosis both in vitro and in vivo.

Atopic dermatitis (AD) is an inflammatory skin disease that produces a variety of inflammatory cytokines and chemokines. Chitinase-3-like protein 1 (CHI3L1, YKL-40) significantly contributes to AD-associated inflammatory response and is highly expressed in patients with AD. Therefore, this study elucidated the effects and potential mechanisms of human YKL-40 antibody on AD-affected skin.

In vitro assessment of the inhibitory effect of antiplatelet drugs on platelet aggregation is frequently employed to guide personalized antiplatelet therapy in clinical practice. However, existing methods for detecting platelet aggregation rely heavily on high concentrations of exogenous agonists, which may obscure part of the inhibitory effect of antiplatelet drugs and lead to an underestimation of their effects. This study validates a novel analytical strategy for evaluating the effects of antiplatelet drugs by quantifying the microscopic three-dimensional morphological parameters of platelet aggregates formed through spontaneous aggregation on a glass surface.
