File Description [top]

MEDLINE (Medical Literature, Analysis, and Retrieval System Online), produced by the U.S. National Library of Medicine (NLM), is the U.S. National Library of Medicine's premier bibliographic database that contains more than 15 million references to journal articles in life sciences with a concentration on biomedicine. The broad coverage of the database includes basic biomedical research and the clinical sciences since 1950 including nursing, dentistry, veterinary medicine, pharmacy, allied health, and pre-clinical sciences. MEDLINE also covers life sciences that are vital to biomedical practitioners, researchers, and educators, including some aspects of biology, environmental science, marine biology, plant and animal science as well as biophysics and chemistry. Increased coverage of life sciences began in 2000. The database also includes records that cover the field of space life science and date from 1961 to the present. Examples of these records include basic bone and muscle physiology, psychological effects of isolation, and gravitational effects on plants.

MEDLINE is indexed using NLM's controlled vocabulary, MeSH^® (Medical Subject Headings). An online thesaurus is available to aid in locating MeSH^® descriptors.

Abstracts, which are taken directly from the published articles, are included for more than 62% of the records added from 1975 forward. Records added before 1975 do not contain abstracts; records added from 1985 to the present have abstracts for about 70% of the records. Approximately 400,000 records are added per year, of which more than 76% are in English.

Records that previously would have been added to AIDSLINE, HealthSTAR, and Toxline are now part of the MEDLINE database. MEDLINE also contains In Process records (formerly known as PreMEDLINE) and In Data Review records. In addition, more than 100,000 records from POPLINE, formerly a standalone database available through NLM, were added to MEDLINE in 2003. These records cover family planning, contraception, fertility, and population issues with data from 1980 to 2000.

/AB	`BACKGROUND: Postnatal growth of the heart chiefly involves nonproliferative cardiomyocyte`
	`enlargement. Cardiac hypertrophy exists in a "physiological" form that is an adaptive`
	`response to long-term exercise training and as a "pathological" form that often is a`
	`maladaptive response to provocative stimuli such as hypertension and aortic valvular`
	`stenosis. A signaling cascade that includes the protein kinase Akt regulates the growth`
	`and survival of many cell types, but the precise role of Akt1 in either form of cardiac`
	`hypertrophy is unknown. METHODS AND RESULTS: To evaluate the role of Akt1 in physiological`
	`cardiac growth, akt1(-/-) adult murine cardiac myocytes (AMCMs) were treated with IGF-1,`
	`and akt1(-/-) mice were subjected to exercise training. akt1(-/-) AMCMs were resistant to`
	`insulin-like growth factor-1-stimulated protein synthesis. The akt1(-/-) mice were found`
	`to be resistant to swimming training-induced cardiac hypertrophy. To evaluate the role of`
	`Akt in pathological cardiac growth, akt1(-/-) AMCMs were treated with endothelin-1, and`
	`akt1(-/-) mice were subjected to pressure overload by transverse aortic constriction.`
	`Surprisingly, akt1(-/-) AMCMs were sensitized to endothelin-1-induced protein synthesis,`
	`and akt1(-/-) mice developed an exacerbated form of cardiac hypertrophy in response to`
	`transverse aortic constriction. CONCLUSIONS: These results establish Akt1 as a pivotal`
	`regulatory switch that promotes physiological cardiac hypertrophy while antagonizing`
	`pathological hypertrophy.`

³As of 2006, the only remaining Check Tags are: Male and Female.

⁴Beginning in June 1980. Also /IF.

⁵CAS Registry Number, Enzyme Commission Number, Gene Symbol, Enzyme Name, and Chemical Name display in /ID.

⁶Gene Symbol included 1991-1995; searchable using /DE or /ID; displayable either in the DE field or in the ID field.
