We present confirmatory evidence for the presence of TMPRSS2, CD147, and GRP78 protein in vitro in airway epithelial cells and confirm broad in situ protein expression of CD147 in the respiratory mucosa.Ĭollectively, our data suggest the presence of a mechanism dynamically regulating ACE2 expression in human lung, perhaps in periods of SARS-CoV-2 infection, and also suggest that alternate receptors for SARS-CoV-2 exist to facilitate initial host cell infection. Consistent with gene expression, rare ACE2 protein expression was observed in the airway epithelium and alveoli of human lung. We demonstrate absent to low ACE2 promoter activity in a variety of lung epithelial cell samples and low ACE2 gene expression in both microarray and scRNAseq datasets of epithelial cell populations. To determine the expression and in situ localization of candidate SARS-CoV-2 receptors in the respiratory mucosa, we analyzed gene expression datasets from airway epithelial cells of 515 healthy subjects, gene promoter activity analysis using the FANTOM5 dataset containing 120 distinct sample types, single cell RNA sequencing (scRNAseq) of 10 healthy subjects, immunoblots on multiple airway epithelial cell types, and immunohistochemistry on 98 human lung samples. Additional host molecules including ADAM17, cathepsin L, CD147, and GRP78 may also function as receptors for SARS-CoV-2. ACE2 and TMPRSS2 have recently been implicated in SARS-CoV-2 viral infection. SARS-CoV, the agent responsible for the 2003 SARS outbreak, utilizes ACE2 and TMPRSS2 host molecules for viral entry. It’s also not hard to see that it is trivial to implement all kinds of genetic modification (mutation, inversion, insertion, recombination, and so on) with the guarantee that all resulting offspring encode correct, error-free programs.In December 2019, SARS-CoV-2 emerged causing the COVID-19 pandemic. z ( v G O v a l l ) / ( S D ( v G O ) / n G O), where.
#GENE EXPRESSION C ARTOON CODE#
It’s not hard to see that, despite their fixed length, each gene has the potential to code for expression trees of different sizes and shapes, with the simplest composed of only one node (when the first element of a gene is a terminal) and the largest composed of as many nodes as there are elements in the gene (when all the elements in the head are functions with maximum arity). Functional category analysis: For each gene ontology (GO) category with >50 genes, we computed a normalized expression variation ( z -score) from the variations of all members of that category. Which, in this case, only uses 8 of the 31 elements that constitute the gene. The randomly generated string below is an example of one such gene: 0123456789012345678901234567890 *b+a-aQab+//+b+babbabbbababbaaa And if we choose a head length of 15, then t = 15 (2 − 1) + 1 = 16, which gives a gene length g of 15 + 16 = 31. For example, for a gene created using the set of functions F =, n max = 2. Where h is the head’s length and n max is maximum arity. The head is used mainly to encode the functions and variables chosen to solve the problem at hand, whereas the tail, while also used to encode the variables, provides essentially a reservoir of terminals to ensure that all programs are error-free.įor GEP genes the length of the tail is given by the formula: The genes of gene expression programming are therefore composed of two different domains – a head and a tail – each with different properties and functions.

The reason for these noncoding regions is to provide a buffer of terminals so that all k-expressions encoded in GEP genes correspond always to valid programs or expressions. This means that there might be sequences in the genes that are not expressed, which is indeed true for most genes. The k-expressions of gene expression programming correspond to the region of genes that gets expressed.
