Cordyceps militaris, a member of Ascomycota, a mushroom referred to as caterpillar Dong-chung-ha-cho, is commercially valuable because of its high content of bioactive substances including cordycepin and its potential for artificial cultivation. Cordycepin (3'-deoxyadenosine) is highly associated with the pharmacological effects of C. militaris. C. militaris is heterothallic in that two mating type loci, idiomorph MAT1-1 and MAT1-2, exist discretely in two different spores. In this study, nine C. militaris strains were mated with each other to prepare new strains that produced a larger amount of cordycepin than the parent strains...

Light is a necessary environmental factor for production of conidia and pigment, formation of stroma, and development of Cordyceps militaris, a well-known edible and medicinal mushroom. In this study, an obvious rhythm loop was observed in certain strains of C. militaris under conditions of alternating 12-hour intervals of dark and light. A possibly related gene, Cmvvd, the homologue of the blue-light photoreceptor of Neurospora crassa, was cloned from the genome of C. militaris. The protein CmVVD is predicted to be 203 amino acids in length and is characterized by the presence of a light, oxygen, or voltage domain...

Cordyceps militaris, known as Dong-Chong-Xia-Cao, produces the most cordycepin among Cordyceps species and can be cultured artificially. For these reasons, C. militaris is widely used as herb or functional food in the East Asia. In this study, we developed a new strain of C. militaris that produces higher cordycepin content than parent strains through mating-based sexual reproduction. Twenty parent strains were collected and identified as C. militaris based on internal trasncrived spacer and rDNA sequences...

Cryptochromes (CRYs) belong to the photolyase/cryptochrome flavoprotein family, which is widely distributed in all kingdoms. A phylogenetic analysis indicated that three Cordyceps militaris proteins [i.e., cryptochrome DASH (CmCRY-DASH), (6-4) photolyase, and cyclobutane pyrimidine dimer (CPD) class I photolyase] belong to separate fungal photolyase/cryptochrome subfamilies. CmCRY-DASH consists of DNA photolyase and flavin adenine dinucleotide-binding domains, with RGG repeats in a C-terminal extension. Considerably, more carotenoids and cordycepin accumulated in the ΔCmcry-DASH strain than in the wild-type or ΔCmwc-1 strains, indicating an inhibitory role for CmCRY-DASH in these biosynthetic pathways...

Cordyceps militaris has been used in traditional Chinese medicine for many years, but its frequent degeneration during continuous maintenance in culture can lead to substantial commercial losses. In this study, a degenerated strain of C. militaris was obtained by subculturing a wild-type strain through 10 successive subcultures. The relative abundance of the 2 mating types seems to be out of balance in the degenerated strain. By cross-mating 4 single-ascospore isolates (2 for MAT 1-1 and 2 for MAT 1-2) from the degenerated strain, we were able to restore fruiting body production to wild-type levels...

Cordyceps militaris has commercially been cultivated, but its degenerated subcultures have gradually resulted in the reduced production. In this study, the biological characteristics and DNA change of degenerated strains of C. militaris were analyzed in detail. The results showed that the degenerated strains exhibited the lower growth rate, and the deficiency in fruit body formation and pigment production. The degradation of strains was not attributable to DNA changes identified by RAPD and SRAP. Compared to normal strains, the biochemical indexes of degradation strains and normal strains showed that the carotenoid content of degradation strains was significantly lower, the activities of cellulase and amylase of degradation strains were slight lower, and the EPS content was lower, but the IPS was higher...

Pathophysiological events that modulate the progression of structural changes in osteoarthritis (OA) include the secretion of inflammatory molecules, such as proinflammatory cytokines. Interleukin-1beta (IL-1β) is the prototypical inflammatory cytokine that activates OA synovial cells to release cytokines and chemokines in support of the inflammatory response. The monocyte chemoattractant protein-1 (MCP-1/CCL2) is one of the key chemokines that regulate migration and infiltration of monocytes in response to inflammation...

Medicinal plants are affluent sources of several effectual natural drugs. Among them cordycepin which is extracted from Cordyceps militaris is a hopeful chemotherapy agent due to its extensive anti-inflammatory, anti-proliferative, antioxidant, and antitumor characteristics. This study investigated the efficacy of cordycepin in the context of human gastric cancer SGC‑7901 and searched for the cell death procedure. Cordycepin incorporates mitochondrial-mediated apoptosis in SGC‑7901 cells with the help of regulating mitochondrial extrinsic pathways by inhibition of A3AR and drive activation of DR3, which promote the activation of PI3K/Akt protein expression as well as collapse of mitochondrial membrane potential (MMP)...

Cordyceps militaris produces cordycepin (3'-deoxyadenosine), which has various activities, including anti-oxidant, anti-tumoral, anti-viral, and anti-inflammatory. Ribonucleotide reductase (RNR) seems to be a candidate to produce cordycepin in C. militaris because RNR catalyzes the reduction of nucleotides to 2'-deoxynucleotides, whose structures are similar to that of cordycepin. However, the role of RNR has not been confirmed yet. In this study, complementary DNAs (cDNAs) of C. militaris RNR (CmRNR) large and small subunits (CmR1 and CmR2) were cloned from C...

Cordyceps militaris is a fungus used for developing health food, but knowledge about its intraspecific differentiation is limited due to lack of efficient markers. Herein, we assembled the mitochondrial genomes of eight C. militaris strains and performed a comparative mitochondrial genomic analysis together with three previously reported mitochondrial genomes of the fungus. Sizes of the 11 mitochondrial genomes varied from 26.5 to 33.9 kb mainly due to variable intron contents (from two to eight introns per strain)...

Cordycepin, a nucleoside-derivative-isolated form Cordyceps militaris, has been reported to suppress tumor cell proliferation and cause apoptosis. This study investigates the effect of cordycepin on the migration of human glioblastoma cells. Cordycepin suppressed the migration of the human glioblastoma cell lines U87MG and LN229 in transwell and wound healing assays. Cordycepin decreased protein expression of integrin α1, focal adhesion kinase (FAK), p-FAK, paxillin and p-paxillin. The lysosomal inhibitor NH4Cl blocked the ability of cordycepin to inhibit focal adhesion protein expression and glioma cell migration...

Cordycepin, a main active composition extracted from Cordyceps militaris, has been reported to exert anti-tumor activity in a broad spectrum of cancer types. However, the function of cordycepin on human non-small cell lung cancer cells is still obscure. Our present work showed that cordycepin inhibited cell growth by inducing apoptosis and autophagy in human NSCLC cells. Further study revealed that cordycepin triggered extrinsic apoptosis associated with down-regulation of c-FLIPL which suppresses the activity of caspase-8...
