| cpg islands | Areas of increased density of the dinucleotide sequence guanine--phosphate diester--cytosine. They form stretches of DNA several hundred base pairs long and number about 30,000 islands in the mammalian genome. They are unmethylated and the site of frequent mutations. Many of the genes with which the islands are associated are housekeeping genes that are constitutively expressed. (12 Dec 1998) |

| CpG island | <molecular biology> Region of genomic DNA rich in the dinucleotide C G. Methylation of the C in the dinucleotide is maintained through cell divisions and profoundly affects the degree of transcription of the nearby genes and is important in developmental regulation of gene expression. (18 Nov 1997) |
|---|---|
| cpg-rich island | <molecular biology> Areas of DNA which consist mostly of the base pair sequence CGCGCGCG. (alternating cytosine and guanine nucleotide bases) that are usually found upstream of many genes and are thought to help regulate gene expression. They are often methylated (have methyl groups attached to the DNA segments). (28 May 1998) |
| atlantic islands | Widely scattered islands in the atlantic ocean as far north as the azores and as far south as the south sandwich islands, with the greatest concentration found in the caribbean region. They include annobon island, ascension, canary islands, falkland islands, fernando po (also called isla de bioko and bioko), gough island, madeira, sao tome and principe, saint helena, and tristan da cunha. (12 Dec 1998) |
| pacific islands | The islands of the pacific ocean divided into micronesia, melanesia, and polynesia (including new zealand). The collective name oceania includes the aforenamed islands, adding Australia, new zealand, and the malay archipelago (indonesia). (12 Dec 1998) |
| pancreatic islands | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
| virgin islands of the united states | A group of islands in the lesser antilles in the west indies, the three main islands being st. Croix, st. Thomas, and st. John. The capital is charlotte amalie. The virgin islands were discovered by columbus in 1493. Before 1917 the u.s. Virgin islands were held by the danish and called the danish west indies but the name was changed when the united states acquired them by purchase. Virgin refers to the fact that columbus made his discovery on st. Ursula's day - virgins being her legendary companions - or to the resemblance of the chain of islands to a procession of nuns or virgins. (12 Dec 1998) |
| mediterranean islands | Scattered islands in the mediterranean sea. The chief islands are the balearic islands (belong to spain; majorca and minorca are among these), corsica (belongs to france), crete (belongs to greece), cyprus (a republic), the cyclades, dodecanese and ionian islands (belong to greece), malta (a republic), sardinia and sicily (belong to italy). (12 Dec 1998) |
| channel islands | A group of four british islands and several islets in the english channel off the coast of france. They are known to have been occupied prehistorically. They were a part of normandy in 933 but were united to the british crown at the time of the norman conquest in 1066. Guernsey and jersey originated noted breeds of cattle. (12 Dec 1998) |
| indian ocean islands | Numerous islands in the indian ocean situated east of madagascar, north to the arabian sea and east to sri lanka. Included are comoros (republic), madagascar (republic), maldives (republic), mauritius (parliamentary democracy), pemba (administered by tanzania), reunion (a department of france), and seychelles (republic). (12 Dec 1998) |
| islands of Calleja | Dense clusters of very small nerve cells (granule cells) characteristic of the olfactory tubercle at the base of the forebrain. (05 Mar 2000) |
| epimyoepithelial islands | Proliferation of salivary gland ductal epithelium and myoepithelium. Characteristic of benign lymphoepithelial lesions and Sjogren's syndrome. (05 Mar 2000) |
| falkland islands | A british colony in the atlantic islands, comprising two principal islands, east falkland and west falkland. Its capital is stanley. Discovered in 1592, it was not occupied until the french settled there briefly in 1764. Later the english settled there but were expelled by the spanish in 1770. The falklands were claimed by argentina but were occupied in 1833 by the british who, after an april 1982 invasion by argentina, regained them in june. The islands were named by british captain john strong in 1690 for the fifth viscount falkland who financed strong's expedition. The spanish name for the islands, malvinas, is from the french malouins, inhabitants of st. Malo who attempted to colonise the islands in 1764. (12 Dec 1998) |
| Langerhans' islands | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
