    Aim: To identify clinically significant molecular markers of endometrial cancer. Materials and Methods: Cancer and normal endometrial tissue samples from 20 patients of the Gynecology Clinic of Odessa State Medical University (Odessa, Ukraine) with confirmed endometrial cancer were compared for SSR and ISSR polymorphisms. Identified polymorphic fragments from anonymous genome regions situated between microsatellite repeats underwent direct DNA sequencing; analysis of their homology to sequences from human genome database has been performed. Results: No significant variability for the microsatellite loci adjacent to the E2F1, BAX, TCF7L2, C-MYC, WNT1, FES, DCC, P27, THRA, APC, CYP19 and P53 genes was detected. Search for new molecular markers of endometrial cancer within anonymous DNA sequences located between microsatellite repeats revealed 100 bp and 174 bp polymorphic fragments. These fragments were detected correspondingly in 60% and 35% of patients. 100 bp fragment appeared to be homologous to a region within the NFKB gene, 174 bp fragment – to a sequence within the DDR1 gene. Conclusions: NFKB1 and DDR1 genes may be regarded as potential markers for some types of endometrial cancer. This is a first report about possible association of these genes with endometrial cancer.ЦСль: идСнтификация клиничСски Π·Π½Π°Ρ‡ΠΈΠΌΡ‹Ρ… ΠΌΠ°Ρ€ΠΊΠ΅Ρ€ΠΎΠ² Ρ€Π°ΠΊΠ° эндомСтрия.

    Microarray study of gene expression in uterine leiomyoma

    No full text
    Uterine leiomyoma is a most common benign neoplasm in women of reproductive age. It arises from the myometrial compartment of the uterus and may transform in some cases to a malignant phenotype. Aim: To identify the genes involved in pathogenesis of uterine leiomyoma. Methods: We have studied differential gene expression in matched tissue samples of leiomyoma and normal myometrium from the very same people utilizing a cDNA microarray screening method. We also compared our results with previously published microarray data to identify the overlapping gene alterations. Results: Based on this comparison we can divide genes deregulated in our study into two groups. The first group comprises genes that to our knowledge have not been previously reported as deregulated in fibroids: CLDN1, FGF7 (KGF), HNRPM, ISOC1, MAGEC1 (CT7), MAPK12, RFC, TIE1, TNFRSF21 (DR6). The second group consists of genes identified also in previous studies: CCND1 (BCL1), CDKN1A (P21), CRABP2, FN1 and SOX4 (EVI16). In our study FN1 was the most up-regulated gene, occupying the place between the myometrium and fibroids ranging from 2.07 to 3.64, depending of the probe molecule used for detection. Conclusions: Newly identified genes may be regarded as potential diagnostic or prognostic markers of uterine leiomyoma and thus may be very useful as new therapeutic candidates.Π›Π΅ΠΉΠΎΠΌΠΈΠΎΠΌΠ° ΠΌΠ°Ρ‚ΠΊΠΈ являСтся ΠΎΠ΄Π½ΠΈΠΌ ΠΈΠ· Π½Π°ΠΈΠ±ΠΎΠ»Π΅Π΅ распространСнных доброкачСствСнных Π½ΠΎΠ²ΠΎΠΎΠ±Ρ€Π°Π·ΠΎΠ²Π°Π½ΠΈΠΉ ТСнской Ρ€Π΅ΠΏΡ€ΠΎΠ΄ΡƒΠΊΡ‚ΠΈΠ²Π½ΠΎΠΉ сфСры.

    The SiO[2]-B[2]O[3] and SiO[2]-P[2]O[5] films were synthesized by using film forming solutions having a P[2]O[5] content of up to 30% and B[2]O[3] up to 40%. Properties of the filmforming solutions and binary oxides were examined. The physical and chemical processes occurring in the solution during the heat treatment of films were examined. The conditions for producing films of different thicknesses were determined. The kinetic parameters were calculated
