Prognostic markers for glioblastoma multiforme (GBM) are important for patient management. Recent advances have identified prognostic markers for GBMs that use telomerase or the alternative lengthening of telomeres (ALT) mechanism for telomere maintenance. Approximately 40% of GBMs have no defined telomere maintenance mechanism (NDTMM), with a mixed survival for affected individuals. This study...

Abstract Despite initial responsiveness to standard treatments like radiation and chemotherapy, IDH mutant gliomas inevitably recur, become more clinically aggressive, lead untimely death. The aggressive change in clinical outcome is driven by insensitivity conventional methods of treatment, necessitating an improved therapeutic strategy at this stage the disease. Greater than 20% recurrent exh...

The present study aimed to investigate the expression of long non-coding RNA (lncRNA) cyclin dependent kinase inhibitor-2B-antisense RNA 1 CDKN2B-AS1 in patients with peripheral blood of idiopathic pulmonary fibrosis (IPF). A total of 24 patients with IPF and 24 healthy controls were included in the study, four patients with IPF and four healthy controls were selected randomly to extract RNA. T...

Genetic testing for melanoma has yet to enter routine clinical use because of the scarcity of available data on the effect of test reporting. A prospective study of 59 members of Utah CDKN2A/p16 mutation-positive pedigrees was conducted to establish the effect of CDKN2A/p16 genetic test reporting on melanoma early detection intentions and behaviors (total body skin examination and skin self-exa...

We assessed the frequency of genomic deletion of p16INK4A (CDKN2A) in synovial sarcomas (SSs) and its possible association with immunoexpression of p16 and cyclin D1 and the Ki-67 proliferation index using dual-color fluorescence in situ hybridization (FISH) on tissue microarray sections of 41 histologically and molecularly confirmed SSs. A heterozygous p16INK4A gene deletion was identified in ...

زمینه و هدف: امروزه پژوهش های مولکولی نشان می دهد که بعضی از ژن ها در ناحیه پروموتر خود به صورتی متحمل متیلاسیون می شوند که باعث خاموشی یا کاهش بیان ژن های دخیل در مسیرهای رشد سلولی می شود. تشخیص موقعیت متیلاسیون می تواند به عنوان مارکری برای تشخیص سرطان و پیش بینی بیماری باشد. ژن سرکوب گر تومور cdkn2a پروتیینی را رمزگذاری می کند که در مهار cdk4/6 و کاهش سطح فسفریلاسیون پروتیین رتینوبلاستوما (p...

Salivary gland tumours are rare tumours characterized by histopathologic complexity and a wide variety of morphologic features. Studies on genetic changes in different histological subtypes of salivary gland tumours are important to better understand molecular pathogenetic mechanisms and to identify diagnostic and prognostic markers. Data are even more scanty dealing with unusual subtypes of th...

BACKGROUND Lifetime melanoma risk of mutation carriers from families with a germline mutation in the CDKN2A gene is estimated to be 67%. The necessity to include family members in a melanoma surveillance program is widely endorsed, but there is no consensus on which family members should be invited. METHODS In a retrospective follow-up study, we investigated the yield of surveillance of first...

Inactivation of the tumor suppressor gene, CDKN2A, can occur by deletion, methylation, or mutation. We assessed the principal mode of inactivation in childhood acute lymphoblastic leukemia (ALL) and frequency in biologically relevant subgroups. Mutation or methylation was rare, whereas genomic deletion occurred in 21% of B-cell precursor ALL and 50% of T-ALL patients. Single nucleotide polymorp...
