The finding was associated to increased levels of some CDKIs, namely p27(Kip1) and p21(Cip1), whereas ASA did not affected p16(Ink4A) level at any of the concentrations employed. | |||||||||||||||

We also explored whether the association of MC1R variants with melanoma risk differed if the CDKN2A mutations affected p16INK4a alone or both p16INK4 and p14ARF proteins. | |||||||||||||||
| |||||||||||||||
|
For each baseline endoscopy, samples were characterized for 17p LOH spanning TP53, TP53 mutations, DNA content abnormalities including tetraploidy and aneuploidy, 9p LOH spanning the CDKN2A (p16) locus, CDKN2A promoter methylation, and CDKN2A mutation in one biopsy every 2 cm in the Barrett's segment (average = 3.2, range 111 biopsies analyzed per study participant). | |||||||||||||||

and 2, thus affecting p16INK4a protein alone or both p16INK4a and p14ARF proteins (7). | |||||||||||||||

|
Moreover, it is not known whether the associations of MC1R variants with melanoma risk in CDKN2A carriers vary, depending on whether the CDKN2A mutation alters p16INK4A protein alone or both p16INK4A and p14ARF proteins. | |||||||||||||||
| |||||||||||||||
|
We also investigated whether the associations of the frequent MC1R variants and number of MC1R variants with melanoma risk differed according to the type of CDKN2A mutations (mutations affecting p16INK4a protein only vs mutations affecting both p16INK4a and p14ARF proteins). | |||||||||||||||

|
The median ages at examination among affected and unaffected CDKN2A mutation carriers were 47 and 41 years, respectively, in Europe; 42 and 34 years, respectively, in North America; and 54 and 47 years, respectively, in Australia. | |||||||||||||||
| |||||||||||||||
|
A total of 23 nonsynonymous MC1R variants were detected in affected and unaffected CDKN2A mutation carriers of the 186 melanoma-prone families, and four of these variants (V60L, V92M, R151C, and R160W) showed a frequency more than 5% in these mutation carriers across all continents. | |||||||||||||||
| |||||||||||||||
|
Despite the ascertainment of the families through at least two melanoma patients, the frequencies of these four variants in unaffected CDKN2A mutation carriers were similar to those reported in control groups from the same populations (12,18). | |||||||||||||||

| |||||||||||||||
|
In our analysis, the associations of MC1R variants with melanoma risk did not differ statistically significantly depending on whether CDKN2A mutations altered only the p16INK4a protein or both p16INK4a and p14ARF proteins. | |||||||||||||||
| |||||||||||||||
|
Moreover, a number of other genetic alterations for several specific genes including p53, p16INK4a, and Smad4, have been documented [58]. | |||||||||||||||

We also investigated whether the associations of the frequent MC1R variants and number of MC1R variants with melanoma risk differed according to the type of CDKN2A mutations (mutations affecting p16INK4a protein only vs mutations affecting both p16INK4a and p14ARF proteins). | |||||||||||||||
