It has been suggested that the Traditional Chinese herbal preparation Cordyceps sinensis (CS) may have a
beneficial effect in renal disease.We have previously demonstrated bio-activity of naturally occurring CS.
To satisfy increasing demand, CS derivatives have been produced by aseptic mycelia cultivation. The aim
of this work was to compare and contrast the bio-activity of natural CS and two specific products derived
from cultured Cordyceps mycelia, “Jinshuibao Capsule” (Paecilomyces sinensis) and “Corbrin Capsule”
(Hirsutella sinensis). In addition using two different cell systems we examined the potential anti-fibrotic
potential of these products beyond the kidney.
All three preparations antagonised the activity of the pro-fibrotic cytokine TGF-b1 in renal epithelial
cells. Activity was seen in the raw water-soluble components, and the hydrophilic and hydrophobic
extracts from each preparation suggesting that the bio-activity is not confined to one component of the
raw material. In addition to the effects in the renal cell line, similar effects of antagonism of phenotypic
activation of pulmonary fibroblasts by TGF-b1 was also seen suggesting an applicability of these observations
to solid organ fibrosis beyond the kidney. Mechanistically the data demonstrate antagonism of
TGF-b1 activation of Smad signalling and specifically of induction of the hyaladherin TSG-6, which we
have previously demonstrated to orchestrate the formation of a hyaluronan, peri-cellular coats driving
phenotypic cellular activation.
In summary the data support the claim that both naturally occurring and products derived from
cultured Cordyceps mycelia have similar bio-activity which may have particular relevance for solid organ
fibrosis and associated organ dysfunction.
