Signature In The Cell Pdf

“Signature in the Cell is a defining work in the discussion of life's origins and the question of whether life is a product of unthinking matter or of an intelligent mind . In Signature in the Cell, Dr. Stephen Meyer shows that the digital code embedded in DNA points powerfully to a designing intelligence. If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory.

Breast and lung cancers, adenocarcinoma, and medulloblastoma ES cell signatures tested in cancer In one of the first studies aimed at revealing shared gene expression patterns, Chang and associates [ 22 ] collected large-scale data sets that had been acquired from ES cells or adult stem cells, and constructed a gene-module map. From the initial gene-module map, two modules gene sets that distinguish ES cells the ESC-like module and adult stem cells the adult tissue stem cell module were defined. The activities of these two modules were tested using gene expression data sets from various human tumor samples Table 2. Chang's group observed that the ESC-like module is activated in various human epithelial cancers. Moreover, they showed that Myc activates the ESC-like module in epithelial cells. Taking these observations together, the group proposed that the activation of an ES-cell-like transcriptional program via Myc might induce the characteristics of cancer stem cells in differentiated adult cells. Independently, Weinberg and colleagues [ 23 ] defined 13 gene sets in ES cells from previously existing large-scale data sets and placed each of these 13 data sets into one of four categories: ES-expressed, active core factor Nanog, Oct4, and Sox2 targets, PRC targets, and Myc targets. When these data sets were tested using expression profiling data sets from human cancer patients, the activation of ES-cell-specific gene sets such as ES-expressed and the repression of PRC target genes were significantly enriched in poorly differentiated human tumors. A similar approach defined a consensus stemness ranking CSR signature from four different stem cell signatures, and also showed that the CSR signature has prognostic power in several human cancer types [ 24 ]. Notably, an active ES-cell-like expression program has been observed upon inactivation of p53 in breast and lung cancers [ 25 ]. Similar to the function of p53 in the acquisition of pluripotency during reprogramming, the inhibition of p53 or the p53 pathway increases the efficiency of somatic cell reprogramming [ 53 ]. Taken together, these studies clearly show that ES-cell-specific signatures are shared among various human cancers and animal cancer models; but the precise nature of the gene expression pathways remains unclear. Predominant ES cell Myc module in cancer Although ES cells and cancer cells share some properties, cancer cells do not exhibit true pluripotency like that displayed by ES cells. Furthermore, early studies failed to establish that the crucial ES-cell pluripotency genes were actually expressed in cancer cells and could account for the apparent similarities between ES cells and cancer cells [ 55 , 56 ]. So how specific are the proposed ES-cell-specific gene modules?

The latter simply adds the date of the signature to the signature box. Note that this is the date that the document is signed, not the date that you create the signature box. Click "OK" to add the signature box. Adding the Signature 1. Open the Excel document needing a signature if it's not open already. Then open the "Sign" dialog box by either double-clicking the signature line or by right-clicking it and selecting "Sign. Add your signature. To do this, type your name beside the "X" to add a text signature.

Alternatively, click "Select Image" to browse to an image version of your printed signature.

Metabolic Signature of Pluripotent Stem Cells

Another key factor in ES cells, Sox2, was implicated in lung and esophageal squamous cell carcinomas; but the induction of Sox2 in a lung adenocarcinoma cell line promoted squamous traits rather than pluripotency-related characteristics.

This suggests a role for Sox2 as a lineage-survival oncogene rather than as a stemness marker [ 60 ]. Our recent work has shown that the core module, which relates to ES cell core factors, is not significantly enriched in human epithelial tumors [ 20 ].

Thus, the contribution of ES-cell-specific core factors to tumor formation or maintenance is still uncertain. Implications for cancer and medicine The extent to which the study of pluripotent ES cells has provided insights into cancer is remarkable. In addition, the involvement of both oncogenic and tumor suppressor pathways in somatic cell reprogramming suggests that continued study of the relationship between ES cells and cancer cells is worthwhile.

In this section, we discuss how ES cells might be used to accelerate the translation of basic findings into clinically relevant tests and new therapeutic approaches. Classically, cancer cell lines have been employed as convenient biological models when investigating the characteristics of various cancers and as a platform for exploring the activity of chemotherapeutic agents.

Cell lines are not usually a preferred platform for drug screening because they often represent highly selected subpopulations of cancer cells, with accumulated genetic mutations or abnormalities acquired during long-term culture.

The shared signatures of ES cells and cancer cells suggest, however, that ES cells could provide an alternative system for studying pathways relevant to cancers. One strategy is depicted in Figure 1. Subsequently, selected modulators could then be re-validated in cancer cells either in culture or in various transplant protocols.

A variation of this theme is the recent application of gene expression signatures to identify drugs that target specific signaling pathways such as those for Ras, Src, and Myc [ 64 — 66 ].

An activated core module involving Oct4 and Nanog is specific to ES cells. A particularly powerful approach is now afforded by an elegant in silico method based on the 'Connectivity Map' [ 67 , 68 ]. The Connectivity Map encompasses an expanding database of gene expression profiles from a collection of reference cell lines treated with 'perturbagens' [ 69 ].

Validating the concept of mutational signatures with isogenic cell models

In the menu that appears, click the "Microsoft Office Signature Line. Fill in the necessary information in the Signature Setup box that appears.

You can add the suggested signer's name, the suggested signer's title, the suggested signer's email address and any instructions to the signer.

You can leave any or all of these blank, but information about the document and the needed signature may be unclear to others viewing the document. Select the final options for the signature. You have two options with check boxes beside them that read "Allow the signer to add comments in the Sign dialog box" and "Show sign date in signature line.

The latter simply adds the date of the signature to the signature box. Note that this is the date that the document is signed, not the date that you create the signature box.
