Cordycepin, or 3'-deoxyadenosine, is a derivative of the nucleoside adenosine, differing from the latter by the replacement of the hydroxy group in the 3' position with a hydrogen. It was initially extracted from the fungus Cordyceps militaris , [1] but can now be produced synthetically. [2] It is also found in other Cordyceps species as well as Ophiocordyceps sinensis . [3]
Cordycepin is produced in cordyceps as a means of infecting insect populations, due to cordycepin's biological activity [4]
Because cordycepin is similar to adenosine, some enzymes cannot discriminate between the two.[ citation needed ] It can therefore participate in certain biochemical reactions (for example, 3-dA can trigger the premature termination of mRNA synthesis). [5] [6] By acting as an adenosine analog, cordycepin was found to be the most potent molecular circadian clock resetter out of several screened compounds. [7]
Cordycepin has displayed cytotoxicity against some leukemic cell lines in vitro. [8] [9] [10] Additionally, cordycepin has been shown to display an effect in some types of other cancers, such as lung, [11] renal, [12] colon, [13] and breast cancer. [14] Cordycepin has been shown to reduce viable A549 lung cancer cell populations by 50%. [11]
Cordycepin has been found to produce rapid, robust imipramine-like antidepressant effects in animal models of depression, and these effects, similarly to those of imipramine, are dependent on enhancement of AMPA receptor signaling. [15]
Cordycepin has been shown to have anti-inflammatory qualities, [16] as well as the ability to defend against injury from cerebral ischemia in mice. [17]
The miR-17 microRNA precursor family are a group of related small non-coding RNA genes called microRNAs that regulate gene expression. The microRNA precursor miR-17 family, includes miR-20a/b, miR-93, and miR-106a/b. With the exception of miR-93, these microRNAs are produced from several microRNA gene clusters, which apparently arose from a series of ancient evolutionary genetic duplication events, and also include members of the miR-19, and miR-25 families. These clusters are transcribed as long non-coding RNA transcripts that are processed to form ~70 nucleotide microRNA precursors, that are subsequently processed by the Dicer enzyme to give a ~22 nucleotide products. The mature microRNA products are thought to regulate expression levels of other genes through complementarity to the 3' UTR of specific target messenger RNA.
DNA damage-inducible transcript 3, also known as C/EBP homologous protein (CHOP), is a pro-apoptotic transcription factor that is encoded by the DDIT3 gene. It is a member of the CCAAT/enhancer-binding protein (C/EBP) family of DNA-binding transcription factors. The protein functions as a dominant-negative inhibitor by forming heterodimers with other C/EBP members, preventing their DNA binding activity. The protein is implicated in adipogenesis and erythropoiesis and has an important role in the cell's stress response.
Serine/threonine-protein kinase PAK 4 is an enzyme that in humans is encoded by the PAK4 gene.
The Hippo signaling pathway, also known as the Salvador-Warts-Hippo (SWH) pathway, is a signaling pathway that controls organ size in animals through the regulation of cell proliferation and apoptosis. The pathway takes its name from one of its key signaling components—the protein kinase Hippo (Hpo). Mutations in this gene lead to tissue overgrowth, or a "hippopotamus"-like phenotype.
In molecular biology, mir-221 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-210 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
miR-214 is a vertebrate-specific family of microRNA precursors. The ~22 nucleotide mature miRNA sequence is excised from the precursor hairpin by the enzyme Dicer. This sequence then associates with RISC which effects RNA interference.
N6-Methyladenosine (m6A) was originally identified and partially characterised in the 1970s, and is an abundant modification in mRNA and DNA. It is found within some viruses, and most eukaryotes including mammals, insects, plants and yeast. It is also found in tRNA, rRNA, and small nuclear RNA (snRNA) as well as several long non-coding RNA, such as Xist.
In molecular biology mir-301 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-365 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-25 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms. mir-25 levels increase in human heart failure, and treatment with an anti-sense RNA molecule (antagomiR) was recently reported to halt disease progression and improves cardiac function in a mouse heart failure model.
In molecular biology mir-28 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-153 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
In molecular biology mir-186 microRNA is a short RNA molecule. MicroRNAs function to regulate the expression levels of other genes by several mechanisms.
Cordyceps militaris is a species of fungus in the family Cordycipitaceae, and the type species of the genus Cordyceps. It was originally described by Carl Linnaeus in 1753 as Clavaria militaris. There are hundreds of species of cordyceps fungi. Special characteristics of Cordyceps Militaris are its use in traditional Chinese medicine, modern pharmaceuticals, and its relationship with insects and how it disperses.
MicroRNA 495 is a protein that in humans is encoded by the MIR495 gene.
Coiled-coil-helix-coiled-coil-helix domain containing 2 is a protein that in humans is encoded by the CHCHD2 gene.
MicroRNA 141 is a non-coding RNA molecule that in humans is encoded by the MIR141 gene.
MIR22HG, also known as C17orf91, MGC14376, MIRN22, hsa-mir-22, and miR-22 is a human gene that encodes a noncoding RNA (ncRNA).This RNA molecule is not translated into a protein but nonetheless may have important functions.
CKLF-like MARVEL transmembrane domain-containing 5 (CMTM5), previously termed chemokine-like factor superfamily 5, designates any one of the six protein isoforms encoded by six different alternative splices of its gene, CMTM5; CMTM5-v1 is the most studied of these isoforms. The CMTM5 gene is located in band 11.2 on the long arm of chromosome 14.
