p16INK4A Positively Regulates Cyclin D1 and E2F1 through Negative Control of AUF1
BACKGROUND The cyclin-D/CDK4,6/p16(INK4a)/pRB/E2F pathway, a key regulator of the critical G1 to S phase transition of the cell cycle, is universally disrupted in human cancer. However, the precise function of the different members of this pathway and their functional interplay are still not well defined. METHODOLOGY/PRINCIPAL FINDINGS We have shown here that the tumor suppressor p16(INK4a) p...
متن کاملAntagonistic characteristics are positively associated with inflammatory markers independently of trait negative emotionality.
Recent evidence suggests that individuals with certain personality traits are at elevated risk for chronic systemic inflammation. To date, this literature has focused on the related traits of hostility and negative affect (NA). In this study, we examine the covariation of trait measures of hostility and NA with the inflammatory mediators interleukin-6 and C-reactive protein. We also explore whe...
متن کاملCharge density of a positively charged vector boson may be negative.
The charge density of vector particles, for example W(+/-), may change sign. The effect manifests itself even for a free propagation, when the energy of the W-boson satisfies epsilon>sqrt[2]m and the standing wave is considered. The charge density of W also changes sign in a vicinity of a Coulomb center. For an arbitrary vector boson (e.g., for spin 1 mesons), this effect depends on the g-facto...
متن کاملAntimicrobial effects of positively charged surfaces on adhering Gram-positive and Gram-negative bacteria.
The infection of biomaterials is determined by an interplay of adhesion and surface growth of the infecting organisms. In this study, the antimicrobial effects on adhering bacteria of a positively charged poly(methacrylate) surface (xi potential +12 mV) were compared with those of negatively charged poly(methyl methacrylate) (-12 mV) and a highly negatively charged poly(methacrylate) (-18 mV) s...
متن کاملAGC kinase OsOxi1 positively regulates basal resistance through suppression of OsPti1a-mediated negative regulation.
OsPti1a, a functional ortholog of tomato SlPti1, negatively regulates both basal resistance and R-gene-mediated resistance in rice. To investigate the molecular function of OsPti1a in defense responses, we searched for components interacting with OsPti1a using a yeast two-hybrid system. One of the interacting proteins is a Ser/Thr kinase that directly phosphorylates OsPti1a in vitro. This prote...
