Disease relevance of Mki67

  • Moreover, in HCV-infected livers with cirrhosis, activation of STAT1 was detected and correlated positively with liver injury (elevated serum levels of AST) but negatively with hepatocyte proliferation (hepatocyte PCNA and Ki-67 positive immunostaining) [1].
  • RESULTS: In thrombocytotic and thrombocytopenic mice, liver/body weight ratios and Ki-67 labeling indices were significantly increased and significantly decreased, respectively, compared with untreated mice 48 hours post-hepatectomy [2].
  • Selected adenomas were assessed for proliferative activity by Ki-67 immunocytochemistry [3].
  • In all samples tested, overexpression of Ki-67 antigen was shown by immunohistochemistry, indicating a high proliferative index of SCID mice EBV-induced lymphoproliferation [4].
  • MMPs, VEGF, Ki-67 (proliferative protein), and constituents of ECM play a critical role in angiogenesis and underlie neoplastic invasion and metastasis [5].
 

Psychiatry related information on Mki67

  • Additionally, after therapy, Ki67 index showed >4-fold reduction of tumor proliferation in the combination therapy group, which also showed increased intratumoral apoptotic index by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining [6].
 

High impact information on Mki67

  • In contrast, analysis of the A/WySnJ GC response revealed a B cell autonomous proliferative defect associated with reduced or undetectable Ki67 nuclear proliferation antigen expression by GC B cells at all stages of the response [7].
  • Immunohistochemical analysis using lymphatic-specific markers: VEGFR-3, lymphatic endothelial hyaluronan receptor-1, together with the proliferation marker Ki-67 Ab revealed that phVEGF-C transfection potently induced new lymphatic vessel growth [8].
  • The rapid effect of hormone deprivation and resubstitution in the tumor cell proliferation fraction suggests that monoclonal antibody Ki-67 can be used for monitoring the short-term effects of hormonal treatment of prostatic cancer [9].
  • The number of Ki-67-positive tumor cells dropped from an average of 17% in androgen-supplemented, tumor-bearing female BALB/c mice to approximately 1.0% within 10 days after removal of the testosterone (T) implant [9].
  • Administration of supraphysiologic doses of T in intact male mice did not lead to an increase in the number of Ki-67-stained nuclei [9].
 

Chemical compound and disease context of Mki67

 

Biological context of Mki67

  • Assignment1 of the murine Ki-67 gene (Mki67) to chromosome band 7F3-F5 by in situ hybridization [13].
  • This phenotype depended on COX-2-mediated PGE(2) synthesis and correlated with increased expression of proliferation-associated Ki67 in epithelial cells [14].
  • Here, we show p63 expression during teeth and vibrissae morphogenesis in mouse embryos and we also show a correlation with the expression patterns of the epithelial marker keratin 5 and the proliferation marker Ki67 [15].
  • In contrast, anterior pituitaries of Cdk4-null mice at postnatal 8 weeks are extremely hypoplastic with markedly decreased numbers of Ki67+ cells, suggesting impaired cell proliferation [16].
  • The murine Ki-67 cDNA sequence (TSG126) was found to contain 13 tandem repeats, making up more than half of the total protein size [17].
 

Anatomical context of Mki67

  • The Ki-67 protein reappeared in oocytes of growing follicles and was continuously present up to metaphase II [18].
  • Expression of beta-catenin was examined together with the expression of Ki-67, a marker for proliferating cells, or myosin VIIa, a marker for differentiated hair cells [19].
  • Proliferation was assessed in cultured cells and tissue by (3)H-thymidine incorporation and Ki-67 immunostaining, respectively [20].
  • Furthermore, in human failing and nonfailing hearts, similar observations were documented including induction of active caspase 3 and Ki-67 proteins in dilated cardiomyopathic myocytes [21].
  • The aim of the present study was to examine age-related changes in the proliferative capacity of acinar and ductal cells in labial salivary glands of healthy subjects as reflected by AgNOR and Ki-67 parameters [22].
 

Associations of Mki67 with chemical compounds

  • Interestingly, the G(0) cells defined by their low levels of Hoechst 33342 and Pyronin Y staining, and reduced Ki67 and cyclin D expression (representing 21% of the cultured CB population) include some mature erythroid CFCs but very few primitive CFCs, LTC-ICs, or repopulating cells [23].
  • FACS analysis showed that the cells strongly positive for SSEA-1 co-expressed Ki67 proliferation antigen in all the developmental stages examined [24].
  • JTE-522 decreased COX-2 expression and Ki67 labeling index within the coinoculated tumor [25].
  • Although the terminal deoxynucleotidyltransferase-mediated deoxyuridine triphosphate nick end labeling method revealed few apoptotic nuclei, the number of proliferating cells was significantly decreased (Ki-67 antigen study) [26].
  • Testosterone treatment from 21 to 28 days post-castration resulted in an increase in Ki-67 antigen positive cells to 200% of intact controls and a concomitant reduction in p27 expressing cells to about 50% of intact controls [27].
 

Co-localisations of Mki67

  • Moreover, p63 expression in tooth seems not to be fully colocalized with nuclear Ki67 expression [15].
 

Regulatory relationships of Mki67

  • In the present study, we demonstrate that treatment of embryoid bodies grown from pluripotent murine embryonic stem (ES) cells with CT-1 significantly stimulated cardiomyogenesis and increased nuclear expression of the proliferation marker Ki-67 [28].
 

Other interactions of Mki67

  • In order to do this we used nestin-EGFP and TLX-LacZ transgenic mice, as well as labeling for Ki67, a marker for dividing cells [29].
  • The rapid appearance of these tumors from a relatively small pool of infected cells (estimated to be approximately 2 x 10(3) cells per gland by infection with RCAS carrying a GFP gene; RCAS-GFP) was accompanied by a high fraction of cells positive for Ki67, Cyclin D1, and c-Myc, implying strong proliferation competence [30].
  • The proliferative effect of SB216763 was attenuated by an FGF receptor inhibitor but was enhanced by FGF2, with Ki-67-positive cells reaching over 70% of the total cells [31].
  • Wnt3a increased the size of the primary spheres and the number of Ki-67-positive proliferating cells in monolayer culture [31].
  • Growth kinetics in the liver were analyzed as a function of the liver/body weight ratio, the mitotic index, the proliferating cell nuclear antigen labeling index and Ki-67 labeling index [2].
 

Analytical, diagnostic and therapeutic context of Mki67

  • The tumors were analyzed by immunohistochemistry for expression of Ki-67, tissue transglutaminase, and vascular endothelial growth factor [32].
  • Microscopic analysis of the xenograft tumors revealed a reduced Ki-67 labeling and a lower amount of tumor necrosis in FGFR1-IIIb-expressing tumors [33].
  • Immunofluorescence staining of cells coexpressing ras and E6 from either HPV16 or HPV1 revealed that antiproliferative (p16(INK4a)) and proliferative (Ki67) markers were coexpressed in the same cells [34].
  • Concomitant with this, expression of Ki-67, p53 and bcl-2 proteins was increased, and apoptotic cells were decreased as demonstrated by the TUNEL method [35].
  • The average labeling index (LI) for Ki-67 in SRRS group was significantly decreased to 8.43+/-2.22 % compared with the control group (10.37+/-4.91 %) (P<0.05) [36].
