Mitochondrial abnormalities in the pre-synaptic motor nerve terminals are detected at postnatal day 6, which are more pronounced at P15 and accompanied by a loss of synaptic vesicles and synaptophysin protein coupled with NMJs of a smaller size at a time when there is no detectable motor neuron loss.
A novel compound, ferulic acid-bound resveratrol, induces the tumor suppressor gene p15 and inhibits the three-dimensional proliferation of colorectal cancer cells.
A panel of human carcinomas of the exocrine pancreas orthotopically implanted and perpetuated in nude mice and pancreatic cancer cell lines were studied. p15 gene alterations, mainly homozygous deletions that involved exons 1 and/or 2, were found in the 62.5% (5 of 8) of pancreatic xenografts whereas Smad4 gene aberrations were found in one of eight xenografts and in two of seven cell lines.

A previous analysis of these NSCLC samples for p16 gene alterations revealed that the three cases with homozygous deletions of the p15 gene also have homozygous deletions of the p16 gene.
A segment of the gag gene of the human immunodeficiency virus (HIV) (HTLV-IIIB strain), the virus which causes acquired immunodeficiency syndrome (AIDS), has been cloned into the bacterial expression vector, pCQV2, and mapped to the right-hand portion of the gag gene containing the carboxyl-terminal portion of p24 and the amino-terminal portion of p15.

A seizure rechallenge with flurothyl 7 days following TMDT exposure demonstrated longer latencies to the first clonic seizure but a faster progression into the tonic-clonic seizure in P15 and adult survivors as compared to their vehicle-injected counterparts.
A statistically significant association between p16 gene alteration and bladder tumors of low stage (P < .01) and grade (P < .01) was observed; a significant association between p15 gene alteration and tumors of low stage (P < .01) was also detected.
A two-sided t-test was used to evaluate between-group differences in mean H scores and qΔCt values. p15 Expression was significantly increased in melanocytic nevi compared with melanomas (mean H scores, 254.8 versus 132.3; P < 0.001).
Aberrant DNA methylation of a cell cycle regulatory pathway composed of P73, P15 and P57KIP2 is a rare event in children with acute lymphocytic leukemia.
Aberrant hypermethylation was observed in 7 (32%) and 5 (23%) cases accompanied, by immunohistochemical loss of expression for p16 and p15 genes respectively, in both high stage and grade tumors from patients living in radiocontaminated areas, this being especially outstanding for the p16 gene.
Aberrant methylation in the sample of patients with CLL was shown for secreted frizzled-related protein 1 (68.8%), secreted frizzled-related protein 2 (65.6%), death-associated protein kinase 1 (50.0%), E-cadherin (21.9%), secreted frizzled-related protein 4 (15.6%), p15 (9.4%), p16 (6.3%), retinoic acid receptor beta2 (3.1%), secreted frizzled-related protein 5 (3.1%) and tissue inhibitor of matrix metalloproteinases 3 (3.1%).
Abnormalities in the p16, p15 and CDK4 genes that regulate transition through the G1 phase of the cell cycle have been implicated in the malignant progression of astrocytomas.
Acute/lymphomatous ATLL has frequent alterations of p15 (20%) and p16 (28-67%), while chronic/smoldering ATLL has fewer abnormalities of p15 (0-13%) and p16 (5-26%).

All doses of ACTH (range 0.02-1.0 mg/kg s.c.) and all doses but one of AQB-565 in the same range suppressed spasms in P15 rats (treatment stopped on P14).
