The Role of Autophagy in Anti-Cancer and Health Promoting Effects of Cordycepin. Molecules 2021; 26:molecules26164954. [PMID: 34443541 PMCID: PMC8400201 DOI: 10.3390/molecules26164954] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Revised: 08/10/2021] [Accepted: 08/12/2021] [Indexed: 12/18/2022] Open
Abstract
Cordycepin is an adenosine derivative isolated from Cordyceps sinensis, which has been used as an herbal complementary and alternative medicine with various biological activities. The general anti-cancer mechanisms of cordycepin are regulated by the adenosine A3 receptor, epidermal growth factor receptor (EGFR), mitogen-activated protein kinases (MAPKs), and glycogen synthase kinase (GSK)-3β, leading to cell cycle arrest or apoptosis. Notably, cordycepin also induces autophagy to trigger cell death, inhibits tumor metastasis, and modulates the immune system. Since the dysregulation of autophagy is associated with cancers and neuron, immune, and kidney diseases, cordycepin is considered an alternative treatment because of the involvement of cordycepin in autophagic signaling. However, the profound mechanism of autophagy induction by cordycepin has never been reviewed in detail. Therefore, in this article, we reviewed the anti-cancer and health-promoting effects of cordycepin in the neurons, kidneys, and the immune system through diverse mechanisms, including autophagy induction. We also suggest that formulation changes for cordycepin could enhance its bioactivity and bioavailability and lower its toxicity for future applications. A comprehensive understanding of the autophagy mechanism would provide novel mechanistic insight into the anti-cancer and health-promoting effects of cordycepin.

Abstract
In recent decades, interest in the Cordyceps genus has amplified due to its immunostimulatory potential. Cordyceps species, its extracts, and bioactive constituents have been related with cytokine production such as interleukin (IL)-1β, IL-2, IL-6, IL-8, IL-10, IL-12, and tumor necrosis factor (TNF)-α, phagocytosis stimulation of immune cells, nitric oxide production by increasing inducible nitric oxide synthase activity, and stimulation of inflammatory response via mitogen-activated protein kinase pathway. Other pharmacological activities like antioxidant, anti-cancer, antihyperlipidemic, anti-diabetic, anti-fatigue, anti-aging, hypocholesterolemic, hypotensive, vasorelaxation, anti-depressant, aphrodisiac, and kidney protection, has been reported in pre-clinical studies. These biological activities are correlated with the bioactive compounds present in Cordyceps including nucleosides, sterols, flavonoids, cyclic peptides, phenolic, bioxanthracenes, polyketides, and alkaloids, being the cyclic peptides compounds the most studied. An organized review of the existing literature was executed by surveying several databanks like PubMed, Scopus, etc. using keywords like Cordyceps, cordycepin, immune system, immunostimulation, immunomodulatory, pharmacology, anti-cancer, anti-viral, clinical trials, ethnomedicine, pharmacology, phytochemical analysis, and different species names. This review collects and analyzes state-of-the-art about the properties of Cordyceps species along with ethnopharmacological properties, application in food, chemical compounds, extraction of bioactive compounds, and various pharmacological properties with a special focus on the stimulatory properties of immunity.

Abstract
Local healthcare providers often question the possible steroidal activity of traditional Chinese medicine (TCM) herbs or herbal products and implicate them as a cause for adrenal insufficiency or Cushing's syndrome in patients with a history of TCM intake. We conducted a comprehensive database search for evidence of potential glucocorticoid, mineralocorticoid, androgenic or oestrogenic activity of herbs or herbal products. Overall, there are not many herbs whose steroidal activity is well established; among these, most cases were based on preclinical studies. Liquorice root may cause pseudoaldosteronism through interference with the steroidogenesis pathway. Although ginseng and cordyceps have some in vitro glucocorticoid activities, the corroborating clinical data is lacking. Deer musk and deer antler contain androgenic steroids, while epimedium has oestrogenic activity. On the other hand, adulteration of herbal products with exogenous glucocorticoids is a recurrent problem encountered locally in illegal products masquerading as TCM. Healthcare providers should stay vigilant and report any suspicion to the relevant authorities for further investigations.

Abstract
Members of the entomophagous fungi are considered very crucial in the fungal domain relative to their natural phenomenon and economic perspectives; however, inadequate knowledge of their mechanisms of interaction keeps them lagging behind in parallel studies of fungi associated with agro-ecology, forest pathology and medical biology. Ophiocordyceps sinensis (syn. Cordyceps sinensis), an intricate fungus-caterpillar complex after it parasitizes the larva of the moth, is a highly prized medicinal fungus known widely for ages due to its peculiar biochemical assets. Recent technological innovations have significantly contributed a great deal to profiling the variable clinical importance of this fungus and other related fungi with similar medicinal potential. However, a detailed mechanism behind fungal pathogenicity and fungal-insect interactions seems rather ambiguous and is poorly justified, demanding special attention. The goal of the present review is to divulge an update on the published data and provides promising insights on different biological events that have remained underemphasized in previous reviews on fungal biology with relation to life-history trade-offs, host specialization and selection pressures. The infection of larvae by a fungus is not a unique event in Cordyceps; hence, other fungal species are also reviewed for effective comparison. Conceivably, the rationale and approaches behind the inheritance of pharmacological abilities acquired and stored within the insect framework at a time when they are completely hijacked and consumed by fungal parasites, and the molecular mechanisms involved therein, are clearly documented.

Abstract
Sexual dysfunctions including desire, arousal, orgasm, and pain disorders are increasing worldwide due to etiological factors and aging. Several types of treatment are claimed in modern medicine, but they have serious side effects and higher costs. In fact, alternative approaches, such as the intake of plants, fungi, and insects, or their extracts, have also been practiced to enhance sexuality and ameliorate illness with notable successes. However, the scientific evidence related to the mechanisms and efficacy of these alternative medicines is both scarce and all too often unconvincing. Ophiocordyceps sinensis is an Ascomycetes fungus parasitic to Lepidoptera larvae, and has long been used as medicine to treat many illnesses and promote longevity in Chinese society. Previous investigations have shown that O. sinensis has many pharmacological activities. This review has focused on illustrating that O. sinensis can enhance libido and sexual performance, and can restore impaired reproductive functions, such as impotency or infertility, in both sexes.

Abstract
SMP-028 is a new compound for treatment of asthma. Oral administration of SMP-028 to rats was associated with toxicological events in endocrine organs. These events mainly consisted of pathological changes in the adrenal gland, testis, prostate, seminal vesicle, ovaries, and uterus. In this study, we set to clarify whether SMP-028 inhibits steroidogenesis in primary culture cells obtained from rat endocrine organs in vitro. Adrenal cells, testicular cells, and ovarian cells were treated with SMP-028 and the production of steroid hormones, i.e., progesterone, aldosterone, corticosterone, total testosterone, and estradiol from these cells was measured by radioimmunoassay. We found that the production of progesterone from these cells treated with SMP-028 at 1 μM decreased to 16-67% that of the control. These findings indicate that SMP-028 inhibits steroidogenesis in rat endocrine organs in vitro. Considering that free maximum concentration in rats treated with SMP-028 are higher than the IC50 values for the inhibition of steroidogenesis in vitro, it is therefore believed that the toxicological events seen in rats following treatment with SMP-028 are due to inhibition of steroidogenesis in vivo.

Abstract
Introducing the importance of Cordyceps sinensis (CS) and its economics. Alternative artificial cultivation methods for large scale production to meet the world demand for CS. Chemical characterization of compounds in different extracts of CS. Potential health benefits and mechanism of action of compounds in CS. Possible application of whole fungus or its extracts in food and pharmaceutical industries.
Cordyceps sinensis (CS) is a well-known entamophagus fungus, naturally distributed in the Tibetan Plateau of Asia and Himalayas. Recently this synonym is transferred to Ophiocordyceps by both scientific and non-scientific communities. It is widely used as a tonic and medicinal food in traditional Chinese medicine (TCM), as it possess wonderful health benefits. To support its functional attributes, various investigations have been carried out to find out its adaptogenic, aphrodisiac, anti-oxidant, anti-aging, neuroprotective, nootropic, immunomodulatory, anti-cancer and hepatoprotective role. Its fruiting portion as well as the larvae possesses potent bio-active fractions and their composition almost found to be similar in both. The bioactive principles are nucleosides, exo-polysaccharides, sterols and, proteins, among others. Among nucleosides, adenosine and cordycepin are the major biochemical markers. Further, different types of solvent extracts and their mixtures exhibit wide range of pharmacological activities, while the water and methanol extracts with the richest sources of nucleosides and polysaccharides also show wide range of pharmacological activities. This review gives a panoramic view of potential health benefits of various classes of bio-active fractions along with the need for sustainable management of CS for human wellness.

Abstract
The caterpillar fungus Ophiocordyceps sinensis (syn.Cordyceps sinensis), which was originally used in traditional Tibetan and Chinese medicine, is called either "yartsa gunbu" or "DongChongXiaCao ( Dōng Chóng Xià Cǎo)" ("winter worm-summer grass"), respectively. The extremely high price of DongChongXiaCao, approximately USD $20,000 to 40,000 per kg, has led to it being regarded as "soft gold" in China. The multi-fungi hypothesis has been proposed for DongChongXiaCao; however, Hirsutella sinensis is the anamorph of O. sinensis. In Chinese, the meaning of "DongChongXiaCao" is different for O. sinensis, Cordyceps spp., and Cordyceps sp. Over 30 bioactivities, such as immunomodulatory, antitumor, anti-inflammatory, and antioxidant activities, have been reported for wild DongChongXiaCao and for the mycelia and culture supernatants of O. sinensis. These bioactivities derive from over 20 bioactive ingredients, mainly extracellular polysaccharides, intracellular polysaccharides, cordycepin, adenosine, mannitol, and sterols. Other bioactive components have been found as well, including two peptides (cordymin and myriocin), melanin, lovastatin, γ-aminobutyric acid, and cordysinins. Recently, the bioactivities of O. sinensis were described, and they include antiarteriosclerosis, antidepression, and antiosteoporosis activities, photoprotection, prevention and treatment of bowel injury, promotion of endurance capacity, and learning-memory improvement. H. sinensis has the ability to accelerate leukocyte recovery, stimulate lymphocyte proliferation, antidiabetes, and improve kidney injury. Starting January 1(st), 2013, regulation will dictate that one fungus can only have one name, which will end the system of using separate names for anamorphs. The anamorph name "H. sinensis" has changed by the International Code of Nomenclature for algae, fungi, and plants to O. sinensis.

Abstract
Our previous study demonstrated that the fruiting bodies of Cordyceps sinensis, a traditional Chinese medicine, attenuated diabetes-induced weight loss, polydipsia, and hyperglycemia in rats. In the present study, we further compared the anti-hyperglycemic activity of the fermented mycelia and broth of Cordyceps sinensis with that of the fruiting bodies. Male Wistar rats orally administered a placebo (STZ group), fruiting bodies (FB group, 1 g/day), fermented mycelia (MCS group, 1 g/day), fermented broth (BCS group, 1 g/day), or fermented mycelia plus broth (XCS group, 0.5 g/day of each) of Cordyceps sinensis (d1 to d28) were injected with nicotinamide (200 mg/kg) and streptozotocin (65 mg/kg) on d15. Rats fed with a placebo and injected with saline served as the control (CON) group. The amount of water and food consumption (d15 to d29), the 2-hour-postprandial blood glucose concentrations (d21 and d28), and the serum concentrations of fructosamine (d29) were significantly lower in the FB, MCS, BCS, and XCS groups than in the STZ group (one-way ANOVA, p < 0.05). The diabetic rats had significantly higher blood glucose concentrations as measured by the oral glucose tolerance test than the control rats; moreover, these changes were significantly reduced by ingesting the fruiting bodies, fermented mycelia and/or broth of Cordyceps sinensis. Our results revealed that the fermented mycelia and broth of Cordyceps sinensis have anti-hyperglycemic activities similar to those of the fruiting bodies. Therefore, the fermented products of Cordyceps sinensis could be developed as potential anti-diabetic agents or functional foods for persons with a high risk of diabetes mellitus.

Abstract
The effects of Cordyceps sinensis (Caterpillar fungus) and strontium ranelate on ovariectomized osteopenic rats was studied in this paper. After the rats were treated orally with C. sinensis, strontium, and C. sinensis rich in strontium ranelate (CSS) respectively, serum alkaline phosphatase (ALP), tartarate-resistant acid phosphatase (TRAP), serum osteocalcin (OC), homocysteine, C-terminal crosslinked telopeptides of collagen type I (CTX), estradiol, and interferon-gamma (IFN-γ) level were examined. The beneficial effects of CSS on improvement of osteoporosis in rats were attributable mainly to decrease ALP activity, TRAP activity, CTX level, and IFN-γ level. At the same time, CSS also increase the OC and estradiol level in ovariectomized osteopenic rats. This study demonstrates the value of C. sinensis rich in strontium ranelate in the management of postmenopausal osteoporosis in humans.

Abstract
The co-effect of Cordyceps sinensi (CS; caterpillar fungus) and strontium on ovariectomized osteopenic rats was studied in this paper. After the rats were treated orally with CS, strontium (SR), and CS rich in strontium (CSS), respectively, the urine calcium, plasma calcium, plasma phosphorus, bone mineral content, mechanical testing, and the mass of uterus, thymus, and body were examined. Both CSS and SR have a positive effect on mechanical strength and mineral content of ovariectomized osteopenic rats. However, femoral neck strength in the CSS-treated group was higher than those in the SR-treated groups. CSS and SR significantly decreased urinary calcium excretion and plasma total calcium and inorganic phosphate concentrations. On the contrary, CS and CSS significantly increased weights of atrophic uteri and weights of body and also decreased the thymus mass in animals, whereas SR did not exhibit any such effects. Our experiments have demonstrated that CSS possess a preferable effect against the decrease of bone strength and bone mineral mass caused by osteoporosis. It was caused by the co-effect of CS and strontium. The mechanism of it includes decreases bone resorption, increases bone formation, increases in body weight, and enhances 17β-estradiol-producing as well as enhancing the immune functions in animals. The data provide an important proof of concept that CSS might be a new potential therapy for the management of postmenopausal osteoporosis in humans.

Abstract
Abstract
Cordyceps species, including C. sinensis, C. militaris, C. pruinosa and C. ophioglossoides, are prized traditional medicinal materials. The aim of this article is to review the chemical constituents and pharmacological actions of Cordyceps species. The chemical constituents include cordycepin (3′-deoxyadenosine) and its derivatives, ergosterol, polysaccharides, a glycoprotein and peptides containing α-aminoisobutyric acid. They include anti-tumour, anti-metastatic, immunomodulatory, antioxidant, anti-inflammatory, insecticidal, antimicrobial, hypolipidaemic, hypoglycaemic, anti-ageing, neuroprotective and renoprotective effects. Polysaccharide accounts for the anti-inflammatory, antioxidant, anti-tumour, anti-metastatic, immunomodulatory, hypoglycaemic, steroidogenic and hypolipidaemic effects. Cordycepin contributes to the anti-tumour, insecticidal and antibacterial activity. Ergosterol exhibits anti-tumour and immunomodulatory activity. A DNase has been characterized.

Abstract
Cordyceps sinensis has been used as nutritious food and medicine in Chinese society. CS can inhibit tumor growth and induce tumor cell apoptosis. CS induced MA-10 mouse Leydig tumor cell death, but the anti-tumor mechanisms are not fully understood. Thus, the aim of this study was to investigate the apoptotic effect of CS on MA-10 cells and determine the molecular mechanism. CS (2-10 mg/ml) was added to MA-10 cells at different time scales (0-24 h). The condensation of DNA chromatin and apoptotic nuclear fragmentation increased in CS-treated MA-10 cells. Western blot analysis showed that 3 hours of CS treatment caused an increase in caspase-3 and -8 expressions only, which provided further evidence for the involvement of caspase-3 and -8 in CS-induced MA-10-cell apoptosis. CS blocked NF-?B protein expression in a dose-dependent relationship. CS induces MA-10 cell apoptosis by activating caspase-8-dependent and caspase-9-independent pathways and downregulating NF-?B protein expression.

Abstract
Medicinal mushrooms, including Cordyceps militaris, have received attention in Korea because of their biological activities. In the fruiting body and in corpus of C. militaris, the total free amino acid content was 69.32 mg/g and 14.03 mg/g, respectively. In the fruiting body, the most abundant amino acids were lysine, glutamic acid, proline and threonine. The fruiting body was rich in unsaturated fatty acids, which comprised about 70% of the total fatty acids. The most abundant unsaturated acid was linoleic acid. There were differences in adenosine and cordycepin contents between the fruiting body and the corpus. The adenosine concentration was 0.18% in the fruiting body and 0.06% in the corpus, and the cordycepin concentration was 0.97% in the fruiting body and 0.36% in the corpus.

Abstract
Traditional Chinese medicines (TCM) are growing in popularity. However, are they effective? Cordyceps is not studied as systematically for bioactivity as another TCM, Ganoderma. Cordyceps is fascinating per se, especially because of the pathogenic lifestyle on Lepidopteron insects. The combination of the fungus and dead insect has been used as a TCM for centuries. However, the natural fungus has been harvested to the extent that it is an endangered species. The effectiveness has been attributed to the Chinese philosophical concept of Yin and Yang and can this be compatible with scientific philosophy? A vast literature exists, some of which is scientific, although others are popular myth, and even hype. Cordyceps sinensis is the most explored species followed by Cordyceps militaris. However, taxonomic concepts were confused until a recent revision, with undefined material being used that cannot be verified. Holomorphism is relevant and contamination might account for some of the activity. The role of the insect has been ignored. Some of the analytical methodologies are poor. Data on the "old" compound cordycepin are still being published: ergosterol and related compounds are reported despite being universal to fungi. There is too much work on crude extracts rather than pure compounds with water and methanol solvents being over-represented in this respect (although methanol is an effective solvent). Excessive speculation exists as to the curative properties. However, there are some excellent pharmacological data and relating to apoptosis. For example, some preparations are active against cancers or diabetes which should be fully investigated. Polysaccharides and secondary metabolites are of particular interest. The use of genuine anamorphic forms in bioreactors is encouraged.

Abstract
The caterpillar-shaped Chinese medicinal mushroom (DongChongXiaCao) looks like a worm in the winter and like a grass in the summer. The fruiting body has been regarded as popular folk or effective medicines used to treat human diseases such as asthma, bronchial and lung inflammation, and kidney disease. The fruiting bodies of Paecilomyces tenuipes that formed on the living silkworm (Bombyx mori) host were used in this examination. This study was carried out to investigate the proximate composition, soluble sugar, amino acid and fatty acid profiles, and contents of the bioactive ingredient including adenosine and D-mannitol in the fruiting-bodies. The moisture content was 57.56%. Soluble sugars found were glycerol, glucose, mannitol and sucrose, and the contents exceeded 24 mgg(-1)dry weight. Total free amino acid content was 17.09 mg g(-1)dry weight. Arginine, glycine, proline and tyrosine were main amino acids. The content of oleic acid in fatty acids was high. Adenosine was more abundant in fruiting bodies than corpus.

Abstract
The in vitro effect of extracted fractions of Cordyceps sinensis (CS) mycelium on hCG-treated testosterone production from purified normal mouse Leydig cells was examined. Different fractions extracted from CS (F1-water soluble polysaccharide, F2- water soluble protein and F3- poorly water soluble polysaccharide, and protein) were added to Leydig cells with hCG, and the production of testosterone was determined by radioimmunoassay (RIA). Testosterone productions stimulated by hCG in mouse Leydig cells were suppressed by F2 at 10 mg/ml and F3 at doses from 3 to 10 mg/ml, respectively. F2 and F3 at 10 mg/ml did inhibit dbcAMP-stimulated testosterone productions which indicated that F2 and F3 might affect steroidogenesis at the site after the formation of cyclic AMP. Finally, cycloheximide inhibited F2- and F3-treated mouse Leydig cell testosterone production.

Abstract
Cordyceps sinensis (CS) mycelium stimulates steroidogenesis in MA-10 mouse Leydig tumor cells, but the mechanisms remain unclear. In this study, MA-10 cells were treated with different reagents in the presence or absence of CS (10 mg/ml) for 3 h to determine the mechanisms. Results illustrated that CS activated the Gsalpha protein subunit, but not Gialpha, to induce cell steroidogenesis. Moreover, PKA inhibitors inhibited 37% of CS-stimulated steroidogenesis, which demonstrated that CS might enhance the cAMP-PKA pathway to affect MA-10 cell steroidogenesis. Because of incomplete inhibition by PKA inhibitors, we also examined the PKC pathway. PKC inhibitor, phospholipase C inhibitor, and calmodulin antagonist blocked 35-52% of CS-stimulated steroidogenesis in MA-10 cells, strongly suggesting that CS had activated the PKC pathway. Co-treatment with PKA and PKC inhibitors abolished 61% of CS-stimulated steroid production, indicating that CS simultaneously activated PKA and PKC pathways. Moreover, CS induced the expression of steroidogenic acute regulatory (StAR) protein in dose- and time-dependent relationships, and PKA inhibitor, PKC inhibitor, or co-treatment with both inhibitors suppressed it. These data support that CS activates both PKA and PKC signal transduction pathways to stimulate MA-10 cell steroidogenesis.

Abstract
This study aimed to elucidate pharmacological activities of Cordyceps militaris. The 70% ethanolic extracts of cultured mycelia (CME) and fruiting bodies (FBE) of Cordyceps militaris were prepared. CME was able to directly scavenge the stable free radical diphenyl-2-picrylhydrazyl (DPPH), indicating its antioxidant activity. Both CME and FBE showed topical anti-inflammatory activity in the croton oil-induced ear edema in mice. CME was found to contain acute anti-inflammatory activity, which was evaluated using the carrageenin-induced edema, and also strong antinociceptive activity in writhing test. CME and FBE contain potent inhibitory activity on the chick embryo chorioallantoic membrane (CAM) angiogenesis in a dose-dependent manner. Cordycepin, a metabolite of Cordyceps militaris, appeared to be at least partly responsible for its anti-inflammatory and anti-angiogenic activities. CME concentration-dependently inhibited the NO production and iNOS expression upon stimulation by lipoposaccharide in RAW 264.7, a murine macrophage cell line. In brief, we demontrate that Cordyceps militaris possesses anti-inflammatory and antinociceptive activites, and related antioxidant, anti-angiogenic, and NO production-inhibitory activities.

Abstract
Cordyceps sinensis (CS), an Ascomycetes fungus parasitic to Lepidoptera larvae, has been traditionally used as nutritious food for the enhancement in immuno-modulation in Chinese society for a long time. Previous report has demonstrated the CS water extract stimulates in vitro corticosterone production in rat primary adrenal cells. In the present studies, we determined the in vivo effects of CS and its fractions on plasma corticosterone production in mouse. Different concentrations of CS and CS fractions dissolved in water (0.02 and 0.2 mg/g body weight) were fed to immature and mature mice from 1, 3 or 7 d. The plasma levels of corticosterone were determined by radioimmunoassay (RIA), and the weight of adrenal gland and body weight were also evaluated. Results illustrated that plasma corticosterone levels were significantly induced by F2 at 0.02 mg/g body weight with 7 d feeding in immature mice, and by CS at 0.02 mg/g body weight with 3 d feeding and F3 at 0.02 mg/g body weight for 7 d feeding in mature mice, respectively (p < 0.05). There were no differences of adrenal gland weight except there was significant stimulation by CS at 0.2 mg/g body weight with 3 d feeding in mature mice (p < 0.05) and there were significant inhibitions by both dosages of F3 for 3 d feeding in immature mice and F2 for 7 d feeding in mature mice (p < 0.05), respectively. Concerning body weight, the stimulatory effects were observed with CS feeding at 0.2 mg/g body weight for 7 d and F3 feeding at 0.02 mg/g body weight for 3 and 7 d in mature mice. Whereas, the inhibitory effect were observed in F2 feeding at 0.2 mg/g body weight for 7 d in immature mice and at both dosages for 7 d in mature mice, respectively. Taken together, these studies illustrate that CS and its fractions stimulated mouse in vivo corticosterone production. However, CS and its fractions didn't have constant stimulatory or inhibitory effects on the weights of body and adrenal glands.

Abstract
Cordyceps sinensis (CS), an Ascomycetes fungus parasitic to Lepidoptera larvae, has been traditionally used as nutritious food for the enhancement on sexual performance and the restitution of impairment in sexual function in Chinese society. We have previously demonstrated the stimulatory effect of CS and its fractions on steroidogenesis both on primary mouse Leydig cells and MA-10 mouse Leydig tumor cells. In the present studies, we determined the in vivo effects of CS and its fractions on steroidogenesis in mouse. Different concentrations of CS and CS fractions (0.02 and 0.2 mg/g body weight) were fed to immature or mature mice from 1 to 7 days. The plasma levels of testosterone were evaluated by radioimmunoassay. The weights of reproductive organs were also determined. Results illustrated that CS significantly induced plasma testosterone levels both in immature and mature mice in 3 and/or 7 days treatment (p < 0.05). F2 and F3 at 0.02 and/or 0.2 mg/g body weight for different feeding duration could also significantly stimulated plasma testosterone levels both in immature and mature mice (p < 0.05). In general, CS, F2 and F3 didn't have considerable effect on the weights of reproductive organs. Taken together, these studies illustrate that CS and its fractions significantly stimulated in vivo mouse testosterone production.

Abstract
Little scientific evidence exists to support the numerous herbs used to improve diabetes-related metabolic disorders. Cordyceps, a Chinese herbal medicine with fruiting body and carcass, has been proposed to have multiple medicinal activities. The objective of this study was to investigate the effects of fruiting body and carcass of Cordyceps on hyperglycemia. Male Wistar rats administered with placebo (STZ group), 1 g of fruiting body (FB group), 1 g of carcass (CC group), or 1g of fruiting body plus carcass (CF group) of Cordyceps for four weeks (d1 to d28) were injected with nicotinamide (200 mg/kg) and streptozotocin (65 mg/kg) on d15. Animals fed with placebo and injected with saline acted as the controls (CON group). The results showed that water intake (d15 to d29), changes in fasting blood glucose concentration (d15 to d26), and serum concentrations of fructosamine (d29) were significantly greater in the STZ, CC and CF groups than in the CON and FB groups (one-way ANOVA, P < 0.05). The diabetic rats had significantly lower weight gain and higher blood glucose response in oral glucose tolerance test than the control rats; and these changes were significantly reduced by administrating the fruiting body of Cordyceps. Our results revealed that fruiting body, not carcass, of Cordyceps attenuated the diabetes-induced weight loss, polydipsia and hyperglycemia, and these improvements suggest that fruiting body of Cordyceps has a potential to be the functional food for diabetes.

Abstract
There is increasing evidence that 17beta-estradiol (E2) directly influences the quality of maturing oocytes and thus the outcome of assisted reproduction treatment. Although Cordyceps sinensis (CS) mycelium, a Chinese herbal medicine, is believed to enhance libido and fertility in both sexes, the mechanism of its effect in women has not been determined. The aim of the present study was to evaluate the effects of CS on steroidogenic enzyme expression and E2 biosynthesis in human granulosa-lutein cells (GLC). We found that CS induced E2 production by GLC in a dose- and time-dependent manner and that a 3-h treatment with CS induced increased levels of mRNAs coding for the P450 side chain cleavage enzyme (P450scc), 3beta-hydroxysteroid dehydrogenase (3beta-HSD), and aromatase. Western blot analysis demonstrated that, after treatment with CS for 3 h, protein levels of steroidogenic acute regulatory protein (StAR) and aromatase were upregulated while P450scc and 3beta-HSD levels showed no substantial change. New protein synthesis was required for CS-induced E2 production because it was abrogated by cycloheximide pretreatment. Addition of 22(R)-hydroxycholesterol, thus bypassing the need for StAR protein, did not induce as much E2 production as CS treatment, indicating that upregulation of StAR protein was not the only factor contributing to CS-induced steroidogenesis. Cotreatment of GLCs with CS and aminoglutethimide, an aromatase inhibitor, completely abolished CS-induced E2 production. In conclusion, treatment of GLCs with CS results in increased E2 production due, at least in part, to increased StAR and aromatase expression. These data may help in the development of treatment regimens to improve the success rate of in vitro fertilization.

Abstract
We demonstrate the mechanism by which Cordyceps sinensis (CS) mycelium regulates Leydig cell steroidogenesis. Mouse Leydig cells were treated with forskolin, H89, phorbol 12-myristate 13-acetate, staurosporine, or steroidogenic enzyme precursors with or without 3 mg/ml CS; then testosterone production was determined. H89, but not phorbol 12-myristate 13-acetate or staurosporine, decreased CS-treated Leydig cell steroidogenesis. CS inhibited Leydig cell steroidogenesis by suppressing the activity of P450scc enzyme, but not 3beta-hydroxysteroid dehydrogenase, 17alpha-hydroxylase, 20alpha-hydroxylase, or 17beta-hydroxysteroid dehydrogenase enzymes. Thus, CS activated the cAMP-protein kinase A signal pathway, but not protein kinase C, and attenuated P45scc enzyme activity to reduce human chorionic gonadotropin-stimulated steroidogenesis in purified mouse Leydig cells.

Abstract
Conflicting data for the effects of colchicine on cholesterol transport and steroidogenesis raise the question of the role of microtubules in cholesterol transport from the lipid droplet to mitochondria in steroidogenic cells. In this study, using corticosterone radioimmunoassay and immunofluorescence microscopy, we re-evaluated the effects of colchicine on hormone production and morphological changes of lipid droplets' and studied the signaling pathway involved in colchicine-induced steroidogenesis. Colchicine stimulated steroid production in a dose- and time-dependent manner. The structural integrity of both the microtubules and the lipid droplet capsule was destroyed by colchicine treatment. Disruption of the lipid droplet capsule occurred later than microtubule depolymerization. After cessation of colchicine treatment and a 3 h recovery in fresh medium, capsular protein relocated to the droplet surface before the cytoplasmic microtubule network was re-established. beta-lumicolchicine, an inactive analogue of colchicine, disrupted the capsule and increased hormone production without affecting microtubular structure. Thus, microtubule depolymerization is not required for the increase in steroid production and capsular disruption. To explore the signaling pathway involved in colchicine-induced steroidogenesis, we measured intracellular cAMP levels. Unlike ACTH, colchicine did not increase cAMP levels, suggesting that the cAMP-PKA system is not involved. Colchicine and ACTH had additive effects on corticosterone production, whereas colchicine and PMA did not, implying that part of the PKC signaling mechanism may be involved in colchicine-induced steroidogenesis. Cycloheximide, a protein synthesis inhibitor, completely inhibited colchicine-induced steroidogenesis and capsular disruption. These results demonstrate that the steroid production and lipid droplet capsule detachment induced by colchicine are both protein neosynthesis-dependent and microtubule-independent.

Abstract
1. This study investigated the effect of magnolol, a compound purified from Magnolia officinalis, on glucocorticoid production by primary adrenal cell culture. 2. Magnolol increased corticosterone secretion in a dose-dependent manner, this effect being maximal at 40 microM. A similar effect was seen in a minced adrenal gland system. 3. In magnolol-treated cells, the number and total area of cytoplasmic lipid droplets were reduced, suggesting a high utilization rate of cholesterol esters stored in lipid droplets. In control cells, the capsule of the lipid droplet was clearly delineated by immunostaining with antibody A2, whereas capsular staining was discontinuous or undetectable following magnolol treatment. The percentage of decapsulated cells increased significantly from 20% in the control group to 80% in the magnolol-treated group. 4. Magnolol-induced steroidogenesis was not mediated either via the traditional ACTH-cyclic AMP-protein kinase A pathway or by protein kinase C, since the intracellular cyclic AMP level did not change and inhibition of protein kinase A or C did not block the action of magnolol. Furthermore, calcium/calmodulin-dependent protein kinase II was not involved in magnolol-induced steroidogenesis. 5. The stimulatory effect of magnolol on steroidogenesis apparently requires new protein synthesis, since cycloheximide inhibited magnolol-induced corticosterone production by 50%. 6. Although other studies have shown that high concentrations of magnolol inhibit acyl-CoA: cholesterol acyltransferase and 11 beta-hydroxysteroid dehydrogenase in a cell-free system, our data show that, in adrenal cell cultures, low concentrations of magnolol have a stimulatory effect on steroidogenesis, and the glucocorticoid produced may explain the effective control of asthma by Magnolia officinalis.

Abstract
We investigated the effect of water extracts of Cordyceps sinensis (WECS) on Kupffer cell function in rats. Rats were received a single i.v. injection of a colloidal carbon solution and then the clearance rate from the blood were measured. The rats had been daily administered with WECS, p.o. at a dose of 200 mg/kg for 25 days until the day before the injection of colloidal carbon. The half-life of the colloidal carbon in the blood of rats administered WECS 200 mg/kg was significantly shorter than that of the control rats. This suggests that accelerated function of Kupffer cells is partially involved in the anti-metastatic action of WECS.
