Characterization of Podophyllotoxin Yielding Cell Lines ofPodophyllum hexandrum

Influence of an Indirect Precursor on Podophyllotoxin Accumulation in Cell Suspension Cultures of Podophyllum hexandrum

Podophyllum hexandrum is an endangered, commercial source of a naturally occurring lignan podophyllotoxin, which is a precursor of potent anticancer drugs. Cell suspension cultures were established using four-year-old cell line RC4 of P. hexandrum in liquid P1 medium [half strength B5 basal medium supplemented with 1% (w/v) sucrose, 2,4-D (1 mg/l), GA3 (1 mg/l) and BA (0.1 mg/l)]. The effect of...

Methyl Jasmonate Regulates Podophyllotoxin Accumulation in Podophyllum hexandrum by Altering the ROS-Responsive Podophyllotoxin Pathway Gene Expression Additionally through the Down Regulation of Few Interfering miRNAs

Podophylloxin (ptox), primarily obtained from Podophyllum hexandrum, is the precursor for semi-synthetic anticancer drugs viz. etoposide, etopophos, and teniposide. Previous studies established that methyl jasmonate (MeJA) treated cell culture of P. hexandrum accumulate ptox significantly. However, the molecular mechanism of MeJA induced ptox accumulation is yet to be explored. Here, we demonst...

Characterization of Nucleoprotein Extracted from Human Influenza A Virus Cultured in Two Different Cell Lines

Background and Aims: Influenza virus nucleoprotein (NP) has the capacity to be used as subunit vaccine, but little is known about the impact of different cultures on its structure. In the present study we aimed to evaluate and compare the Isoelectric focusing (IEF) property of extracted viral nucleoproteins derived from Madin Darby canine kidney (MDCK) cell line and embryonated chicken eggs (EC...

Functional proteomic characterization of cancer cell lines

Molecular Characterization of Putative Chordoma Cell Lines

Immortal tumor cell lines are an important model system for cancer research, however, misidentification and cross-contamination of cell lines are a common problem. Seven chordoma cell lines are reported in the literature, but none has been characterized in detail. We analyzed gene expression patterns and genomic copy number variations in five putative chordoma cell lines (U-CH1, CCL3, CCL4, GB6...
