• Cyclin-dependent kinase 2, also known as cell division protein kinase 2, or Cdk2, is an enzyme that in humans is encoded by the CDK2 gene. (wikipedia.org)
  • This protein associates with and is regulated by the regulatory subunits of the complex including cyclin E or A. Cyclin E binds G1 phase Cdk2, which is required for the transition from G1 to S phase while binding with Cyclin A is required to progress through the S phase. (wikipedia.org)
  • Cdk2 is capable of binding to many different cyclins, including cyclins A, B, E, and possibly C. Recent studies suggest Cdk2 binds preferentially to cyclins A and E, while Cdk1 prefers cyclins A and B. Cdk2 becomes active when a cyclin protein (either A or E) binds at the active site located between the N and C lobes of the kinase. (wikipedia.org)
  • Due to the location of the active site, partner cyclins interact with both lobes of Cdk2. (wikipedia.org)
  • Cdk2 contains an important alpha helix located in the C lobe of the kinase, called the C-helix or the PSTAIRE-helix. (wikipedia.org)
  • It is important to note that throughout this activation process, cyclins binding to Cdk2 do not undergo any conformational change. (wikipedia.org)
  • Prior to G1 phase, levels of Cdk4 and Cdk6 increase along with cyclin D. This allows for the partial phosphorylation of Rb, and partial activation of E2F at the beginning of G1 phase, which promotes cyclin E synthesis and increased Cdk2 activity. (wikipedia.org)

  • PD-1 suppressed the transcription of SKP2 , the substrate recognition component of the SCF Skp2 ubiquitin ligase that leads p27 kip1 to degradation and resulted in accumulation of p27 kip1 (Figure 2). (shu.edu)
  • Methods and results: Wistar rats underwent ischaemia/reperfusion injury by ligation of the coronary artery followed by injection of adenovirus vectors for D1NLS and CDK4 with or without Skp2. (elsevierpure.com)
  • Compared with rats that received only D1NLS and CDK4, expression of Skp2 improved left ventricular function as measured by the maximum and minimum rates of change in left ventricular pressure, the left ventricle end-diastolic pressure, left ventricle end-diastolic volume index, and the lung/body weight ratio.

  • Skp2 might be a versatile tool to improve the effect of cyclins on post-ischaemic regeneration of cardiomyocytes in vivo. (elsevierpure.com)
  • In order to cure metastatic disease, several approaches are imaginable: (1) locoregional treatment of the primary tumor and all metastatic sites, (2) tumor eradication by excellent systemic anticancer therapy, (3) long-term immunologic tumor control induced by immunotherapy or (4) the combination of these approaches.

  • Participants in the control or experimental arms who experience unacceptable toxicity, disease progression as determined by the investigator according to RECIST v1.1, or loss of clinical benefit as determined by the investigator during Stage 1 will be given the option of receiving a different treatment combination during Stage 2, provided they meet eligibility criteria and a treatment arm is open for enrollment.

  • No Stage 2 treatment is currently available. (uclahealth.org)
  • Additionally, the therapeutic efficacy of PC is still far from satisfaction despite aggressive treatment [ 2 , 3 ]. (oncotarget.com)
  • Disease progression during or after first- or second-line hormonal therapy for locally advanced or metastatic disease (note: at least one line of therapy must have contained a CDK4/6i administered for a minimum of 8 weeks prior to disease progression. (uclahealth.org)
  • Immunohistochemical identification of molecular genetic events in the progression of preneoplastic lesions to spindle cell squamous-cell carcinoma enables early detection of lesions with the potential for malignant progression, thus permitting timely intervention 1,2 . (bvsalud.org)
