This study was undertaken to investigate the effects of salicylic acid (SA) and methyl jasmonate (MeJA) on anthocyanin induction, biomass accumulation, and color value (CV) indices for both pigment content (PC) and pigment production (PP) in callus cultures of Rosa hybrida cv. Pusa Ajay. A concentration-dependent response was exhibited by cultures on SA and(More)
Transcription factors of the nuclear factor-kappaB/rel (NF-kappaB) family may be important in cell survival by regulating unidentified, anti-apoptotic genes. One such gene that protects cells from apoptosis induced by Fas or tumor necrosis factor type alpha (TNF), IEX-1L, is described here. Its transcription induced by TNF was decreased in cells with(More)
CTLA-4 is a T cell antigen that is structurally related to CD28 and serves as a high affinity ligand for the B cell antigen B7-1/2. Unlike CD28, the function of CTLA-4 is unclear, although reports have implicated the antigen in the costimulation of T cells. Recently, phosphatidylinositol 3-kinase (PI 3-kinase) has been implicated in the costimulatory(More)
Tumor necrosis factor receptor-related apoptosis-inducing ligand (TRAIL) can induce apoptosis primarily in cancer cells with little or no effect on normal cells; therefore, it has the potential for use in cancer therapy. TRAIL binding to death receptors DR4 and DR5 triggers the death-inducing signal complex formation and activation of procaspase-8, which in(More)
In vitro carotenoid pigment production in callus cultures of Calendula officinalis L. was investigated using two basal media, semi-solid versus liquid media and varied concentrations of sucrose, ammonium, and nitrate nitrogen. Of the two explants that were evaluated, floret explants were best for callus induction using Murashige and Skoog (MS) medium(More)
BACKGROUND The pro-apoptotic protein Siva-1 functions in both extrinsic and intrinsic cell death signaling; however, the exact contribution of the endogenous Siva-1 to DNA damage-induced apoptosis is unclear. Using cisplatin, a chemotherapeutic drug, to induce DNA damage and cell death, we determined the role of Siva-1. METHODS Cisplatin treated HCT116(More)
