A variety of lectins and antifungal proteins were tested for toxicity against the plant parasitic nematodes Ditylenchus dipsaci and Heterodera glycines. It was found that lectins from the mushrooms Xylaria hypoxylon, Agrocybe cylindracea and Tricholoma mongolicum (TML-1) were the most potent against
Plant peptidase inhibitors play essential roles in the defense systems of plants. A trypsin inhibitor (PHTI) with a molecular mass of 20.5 kDa was isolated from the fresh roots of the medicinal herb, Pseudostellaria heterophylla. The purification process involved ammonium sulfate precipitation, gel
A simple purification protocol, involving ion exchange chromatography on DEAE-cellulose and CM-cellulose and fast protein liquid chromatography-gel filtration on Superdex 75, was employed to isolate a Kunitz-type trypsin inhibitor with antifungal activity and a novel lectin from Pseudostellaria
From the roots of the Chinese medicinal herb Pseudostellaria heterophylla a single-chained lectin with a molecular weight of 36 kDa and high hemagglutinating activity was isolated. The lectin was adsorbed on DEAE-cellulose in 10 mM Tris-HCI buffer (pH 7.4) and was eluted by the same buffer
Pseudostellaria heterophylla (PH) has various pharmacological effects that include immunologic enhancement and anti‑oxidation. However, it remains unclear whether PH exerts beneficial effects in dermatological diseases. The present study examined the effects of PH on a 2,4-dinitrochlorobenzene
Heterophyllin B (HB), an active cyclic peptide, is a compound existing in the ethyl acetate extract of Pseudostellaria heterophylla (Miq.) Pax and exhibited the activity of inhibiting the production of NO and cytokines, such as IL-1β and IL-6, in LPS-stimulated RAW 264.7 macrophages. In addition, HB
OBJECTIVE
To investigate the potential therapeutic effect of novel polysaccharide H-1-2 from pseudostellaria heterophylla against type 2 Diabetes Mellitus (T2DM) and elucidate the underling molecular mechanisms.
METHODS
Relative expression of HIF1α and Sirt1 in T2DM patients was determined via
We aimed to examine the therapeutic potential of polysaccharide H-1-2, a bioactive component of Pseudostellaria heterophylla, against pancreatic cancer, as well as to demonstrate the underlying molecular mechanisms. Invasion and migration of pancreatic cells treated with H-1-2 were evaluated.
