In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Example Input: Context: Several Northern Hemisphere Drosera species have been used in the therapy of respiratory tract infections as the traditional medicine Droserae Herba.', 'To determine the anti-inflammatory effects of Drosera species and to investigate a substitute material for Droserae Herba, we examined the effect of extracts of Drosera rotundifolia, Drosera tokaiensis and Drosera spatulata on activated T cell membrane (aTc-m)-induced inflammatory gene expression in HMC-1 human mast cells.', 'Drosera rotundifolia, Drosera spatulata and Drosera tokaiensis were collected in Japan. Herbs were extracted with 80% EtOH, and subsequently applied to OASIS HLB column. HMC-1 cells were treated with each Drosera column-adsorbed fraction for 15min, and subsequently added to aTc-m and incubated for 16h. Inflammatory gene and protein expressions were determined by DNA microarray, RT-PCR and Western blotting.', 'Drosera rotundifolia and Drosera tokaiensis fractions, but not the Drosera spatulata fraction, suppressed inflammatory gene expression induced by aTc-m in HMC-1 cells.\Question: Do drosera rotundifolia and Drosera tokaiensis suppress the activation of HMC-1 human mast cells?
Example Output: Drosera rotundifolia and Drosera tokaiensis suppressed activation of HMC-1 cells induced by aTc-m. Since the Drosera tokaiensis fraction was more effective than the traditionally used Drosera rotundifolia, Drosera tokaiensis is a likely substitute as a source of Droserae Herba.

Example Input: Context: The BXD2 mouse strain spontaneously develops glomerulonephritis and erosive arthritis. The goal of this study was to identify the antigenic target proteins and epitopes and to unravel the mechanisms by which the related conditions arise in BXD2 mice.', 'Individual hybridomas isolated from the spleen of a 10-month-old BXD2 mouse were injected intraperitoneally into nonautoimmune mice for evaluation of pathogenicity of each autoantibody. Autoantigens were immunoprecipitated with the pathogenic autoantibody L3A4. Autoantigens were identified using enzyme-linked immunosorbent assay, Western blotting, 2-dimensional gel electrophoresis, and matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MS) and tandem MS. Antigenic epitopes were determined using a high-throughput epitope mapping method.', 'The production of autoantibodies in BXD2 mice occurred in an orderly progression, with peak levels of autoantibodies to nitrotyrosine (NT)-modified enolase, Ro, alpha-actin, and heat-shock proteins (HSPs) preceding peak levels of antihistone, anti-DNA, and rheumatoid factor. Two monoclonal autoantibodies, L3A4 and T56G10, were identified that could induce immune complexes, renal disease, and/or arthritis. Both L3A4 and T56G10 were polyreactive, and each reacted with separate sets of autoantigens. The antigenic targets of L3A4 consisted of NT-modified enolase, ATP5b, alpha-actin, and Hsp70 family proteins including Hspa5 and Hsp74. The antigenic epitopes of NT-modified enolase and Hspa5 exhibited sequence homology and cross-reactivity, suggesting that epitope spreading may occur through a molecular mimicry mechanism.\Question: Does production of a novel class of polyreactive pathogenic autoantibodies in BXD2 mice cause glomerulonephritis and arthritis?
Example Output: The polyreactivity of autoantibodies that target a novel class of autoantigens may enable these autoantibodies to induce erosive arthritis or glomerulonephritis either by direct pathogenic mechanisms or indirectly via Fc or immune complex deposition.

Example Input: Context: Hematopoiesis is regulated by proliferation, differentiation, and death. p16(INK4a) has been reported to regulate apoptosis and differentiation of diverse cells, as well as arresting the cell cycle at G1 phase. The aim of this study is to explore the properties of p16 in apoptosis and differentiation of erythroid cells.', 'We transfected the INK4a gene to K562 cells, which defect the INK4a gene, and compared the effect of enforced expression of p16(INK4a) with that of various additives, topoisomerase I inhibitor (SN 38), interferon-alpha, phosphatidyl-inositol-3 kinase inhibitor (LY294002), and serum deprivation, which arrest cell cycle at different phases. We also investigated the role of p16(INK4a) in normal day-6 human erythroid colony-forming cells by transfecting the INK4a gene.', 'p16(INK4a) induced cell cycle arrest at the G0/G1 phase, and promoted erythroid differentiation in viable K562 cells, but induced apoptosis in K562 cells with incomplete differentiation. The apoptosis induced by p16 was accompanied with downregulation of bcl-x and nuclear NF-kappaB. These findings were not observed in K562 cells treated with various additives. p16(INK4a) decreased the cell viability and promoted apoptosis in day-9 ECFC.\Question: Does p16 ( INK4a ) induce differentiation and apoptosis in erythroid lineage cells?
Example Output:
We propose that p16(INK4a) plays a role in maintaining homeostasis during erythroid differentiation, and that the mechanisms for this effect are not confined to those inducing cell cycle arrest.
