Temporary Disruption of the Plasma Membrane Is Required for c-fos Expression in Response to Mechanical Stress

Mechanically stressed cells display increased levels of fos message and protein. Although the intracellular signaling pathways responsible for FOS induction have been extensively characterized, we still do not understand the nature of the primary cell mechanotransduction event responsible for converting an externally acting mechanical stressor into an intracellular signal cascade. We now report that plasma membrane disruption (PMD) is quantitatively correlated on a cell-by-cell basis with fos protein levels expressed in mechanically injured monolayers. When the population of PMD-affected cells in injured monolayers was selectively prevented from responding to the injury, the fos response was completely ablated, demonstrating that PMD is a requisite event. This PMD-dependent expression of fos protein did not require cell exposure to cues inherent in release from cell–cell contact inhibition or presented by denuded substratum, because it also occurred in subconfluent monolayers. Fos expression also could not be explained by factors released through PMD, because cell injury conditioned medium failed to elicit fos expression. Translocation of the transcription factor NF-κB into the nucleus may also be regulated by PMD, based on a quantitative correlation similar to that found with fos. We propose that PMD, by allowing a flux of normally impermeant molecules across the plasma membrane, mediates a previously unrecognized form of cell mechanotransduction. PMD may thereby lead to cell growth or hypertrophy responses such as those that are present normally in mechanically stressed skeletal muscle and pathologically in the cardiovascular system.

The Zebrafish Information Network (ZFIN): a resource for genetic, genomic and developmental research

The Zebrafish Information Network, ZFIN, is a WWW community resource of zebrafish genetic, genomic and developmental research information (http://zfin.org). ZFIN provides an anatomical atlas and dictionary, developmental staging criteria, research methods, pathology information and a link to the ZFIN relational database (http://zfin.org/ZFIN/). The database, built on a relational, object-oriented model, provides integrated information about mutants, genes, genetic markers, mapping panels, publications and contact information for the zebrafish research community. The database is populated with curated published data, user submitted data and large dataset uploads. A broad range of data types including text, images, graphical representations and genetic maps supports the data. ZFIN incorporates links to other genomic resources that provide sequence and ortholog data. Zebrafish nomenclature guidelines and an automated registration mechanism for new names are provided. Extensive usability testing has resulted in an easy to learn and use forms interface with complex searching capabilities.

Mr. Marsh's catalogue, ca. 1764

A half-page handwritten list of books with the author's surname, title, and location in the old Harvard Library, signed "Mr. Marsh." The list includes the note, "Shuckford's Connection is charged to you." The document is undated but presumably was created following the Harvard Hall Fire of 1764 as part of the College's efforts to inventory volumes that were spared because they were checked out at the time of the fire. Many of the books are listed in a charging record for Thomas Marsh recorded in a Harvard library account book (UAIII 50.15.60, Volume 1, Box 95), including "Shuckford's connection" which was charged to Marsh on September 23, 1763.

Diary of Thomas Marsh, 1751

Diary kept in an interleaved almanac from 1751. Entries in the diary are brief and sporadic, recording events including travel, visitors, weather, sermons heard, holidays, illnesses and deaths. Occasional expenses are noted, including ones for hay, cider, bottles, shoes, and doctoring. A few dates of college events are noted, including the semi-annual Corporation meeting and Commencement. On the last page is a list of student names, presumably those tutored by Marsh.

Account book of the executors of the Henry Flynt estate, 1760-1767

The volume contains acknowledgements of the disbursements of Harvard Tutor Henry Flynt's estate written in the hands of the respective beneficiaries. The entries begin on February 27, 1760 following Flynt's death on February 13, 1760, and continue through May 9, 1767. Each receipt includes the date, name of the executors, description of the property, beneficiary's name, and signature. The beneficiaries include the wife of Sol. Davy, Dorothy Jackson, Edmund Quincy, J. Henry Quincy, Esther and Stephen Richard (received by attorney Nicholas Boylston), Dorothy Skinner (also received for her by her husband Richard Skinner), John Wendell, Edmund Wendell, Katherine Wendell, and Oliver Wendell, as well as Harvard College (received by Harvard Treasurer Thomas Hubbard), and the Deacons of the First Church of Cambridge. The volume also includes a loose document titled "Account from Messrs Edmund & Josiah Quincy Settled & Ballanced March 31, 1749."
