Abstract
BACKGROUND Chronic liver diseases (CLD) are the major public health burden due to the continuous increasing rate of global morbidity and mortality. The inherent limitations of organ transplantation have led to the development of stem cell-based therapy as a supportive and promising therapeutic option. However, identifying the fate of transplanted cells in vivo represents a crucial obstacle.
AIM To evaluate the potential applicability of DiD dye as a cell labeling agent for long-term, and non-invasive in vivo tracking of transplanted cells in the liver.
METHODS Magnetically sorted, epithelial cell adhesion molecule positive (1 × 106 cells/mL) fetal hepatic progenitor cells were labeled with DiD dye and transplanted into the livers of CLD-severe combined immunodeficiency (SCID) mice. Near-infrared (NIR) imaging was performed for in vivo tracking of the DiD-labeled transplanted cells along with colocalization of hepatic markers for up to 80 d. The existence of human cells within mouse livers was identified using Alu polymerase chain reaction and sequencing.
RESULTS NIR fluorescence imaging of CLD-SCID mice showed a positive fluorescence signal of DiD at days 7, 15, 30, 45, 60, and 80 post-transplantation. Furthermore, positive staining of cytokeratin, c-Met, and albumin colocalizing with DiD fluorescence clearly demonstrated that the fluorescent signal of hepatic markers emerged from the DiD-labeled transplanted cells. Recovery of liver function was also observed with serum levels of glutamic-oxaloacetic transaminase, glutamate-pyruvate transaminase, and bilirubin. The detection of human-specific Alu sequence from the transplanted mouse livers provided evidence for the survival of transplanted cells at day 80.
CONCLUSION DiD-labeling is promising for long-term and non-invasive in vivo cell tracking, and understanding the regenerative mechanisms incurred by the transplanted cells.

Abstract
Andrographis paniculata (Ap) has been a part of traditional medicine for its anti-inflammatory effects, treatment of snake bites and liver abnormalities. Several investigations have revealed its bioactive components to be andrographolides. The methanolic extracts of leaves from Ap were characterized, the non-andrographolides were identified and screened for anti-proliferative activity. The extracts showed significant toxicity against numerous cancer cells including HeLa, MCF7, BT549, 293 and A549 cells. Anti-proliferative activity and effect on cancer cell invasion (metastatic potential) and cell migration were examined. The extracts revealed significant inhibition of the ability of HeLa cells in repairing the gap created by a vertical wound made on a confluent cell monolayer. Similarly, a 40% reduction in cell migration was observed in presence of the extracts. Significant anti-angiogenic activity in terms of reduced blood capillary formation was observed on the Chorioallantoic membranes of embryonated hen eggs co-inoculated with HeLa cells and the extracts. Analysis of HeLa cells treated with the extracts using flow cytometry indicated the arrest of cell cycle progression at the G2/M phase. Variation in the Bax/Bcl-2 ratio and elevated caspase-3 levels by immunoblotting confirmed cell death induction via the apoptotic pathway. Investigation of the extracts by gas chromatography-mass spectrometry displayed the predominant components to be 2(5H)-Furanone (14.73%), Quinic acid (17.32%), and Phytol (11.43%). These components have been previously known to have anticancer activity, while being studied individually in other plants. This is the first study, to the best of our knowledge, on the anti-proliferative and anti-angiogenic activity of the non-andrographolide components from Ap.

Abstract
Paper-based nucleic acid detection and diagnosis are currently gaining much interest in point-of-care (POC) applications. The major steps involved in any nucleic acid amplification testing (NAAT) based diagnostics are nucleic acid isolation, reverse transcription (RT) (in the case of RNA), amplification and detection. RT is an important step in quantifying the viral load in case of disease diagnosis as well as quantifying gene expression levels in other molecular studies. cDNA synthesis is routinely carried out using a thermal cycler, with the process requiring temperatures between 40ºC to 65ºC. Here we report for the first time an instrument-free RT, performed at room temperature on cellulose-based paper devices. cDNA synthesis on paper was confirmed by RT-PCR and Sanger sequencing of the PCR products. Purified RNA from varied sources such as cell lysate, tissue and blood were used to test the methodology. Synthetic hepatitis C virus (HCV) RNA and human blood RNA were used as proof-of-concept to demonstrate the use of these devices in diagnostic applications. Further, ready-to-use paper-based reverse transcription (PRT) devices have been developed, wherein only the RNA sample is added onto the device and the cDNA can be eluted after 30minutes of incubation at room temperature. The devices were found to be stable for 30 days at -20ºC storage. The cellulose-based PRT devices are simple, time saving and user-friendly for a complete instrument-free cDNA synthesis at room temperature.

Abstract
Efforts towards the development of potential anticancer agents, a new series of imidazo[1,2-a]pyridine-oxadiazole hybrids were synthesized and evaluated for their in vitro anticancer activity against lung cancer (A549) and prostate cancer (PC-3, DU-145) cell lines. Amongst the compounds tested, 6d showed the highest potency on A549 cells with an IC50 value of 2.8 ± 0.02 μM. Flow cytometric analysis of compound 6d treated A549 cells showed apoptosis induction by annexin-v/PI dual staining assay and the effect of 6d on different phases of cell cycle was also analyzed. Target based studies demonstrated the inhibition of tubulin polymerization by 6d at an IC50 value of 3.45 ± 0.51 μM and its effective binding with CT-DNA. Further, the molecular modelling studies revealed that 6d has a prominent binding affinity towards α/β-tubulin receptor with admirable physico-chemical properties.

Abstract
Endometrial hyperplasia (EH) is a condition where uterine endometrial glands show excessive proliferation of epithelial cells that may subsequently progress into endometrial cancer (EC). Modern lifestyle disorders such as obesity, hormonal changes and hyperinsulinemia are known risk factors for EH. A mouse strain that mimics most of these risk factors would be an ideal model to study the stage-wise progression of EH disease and develop suitable treatment strategies. Wdr13, an X-linked gene, is evolutionarily conserved and expressed in several tissues including uteri. In the present study, Wdr13 knockout female mice developed benign proliferative epithelium that progressed into EH at around one year of age accompanied by an increase in body weight and elevated estradiol levels. Molecular characterization studies revealed increase in ERα, PI3K and a decrease in PAX2 and ERβ proteins in Wdr13 mutant mice uteri. Further, a decrease in the mRNA levels of cell cycle inhibitors, namely; p21 and cyclin G2 was seen. Leukocyte infiltration was observed in the uterine tissue of knockout mice at around 12 months of age. These physiological, molecular and pathological patterns were similar to those routinely seen in human EH disease and demonstrated the importance of WDR13 in mice uterine tissue. Thus, the genetic loss of Wdr13 in these mice led to mimicking of the human EH associated metabolic disorders making Wdr13 knockout female mice a potential animal model to study human endometrial hyperplasia.

Abstract
End stage liver diseases (ESLD) represent a major, neglected global public health crisis which requires an urgent action towards finding a proper cure. Orthotropic liver transplantation has been the only definitive treatment modality for ESLD. However, shortage of donor organs, timely unavailability, post-surgery related complications and financial burden on the patients limits the number of patients receiving the transplants. Since last two decades cell-based therapies have revolutionized the field of organ/tissue regeneration. However providing an alternative organ source to address the donor liver shortage still poses potential challenges. The developments made in this direction provide useful futuristic approaches, which could be translated into pre-clinical and clinical settings targeting appropriate applications in specific disease conditions. Earlier studies have demonstrated the applicability of this particular approach to generate functional organ in rodent system by connecting them with portal and hepatic circulatory networks. However, such strategy requires very high level of surgical expertise and also poses the technical and financial questions towards its future applicability. Hence, alternative sites for generating secondary organs are being tested in several types of disease conditions. Among different sites, omentum has been proved to be more appropriate site for implanting several kinds of functional tissue constructs without eliciting much immunological response. Hence, omentum may be considered as better site for transplanting humanized bioengineered ex vivo generated livers, thereby creating a secondary organ at intra-omental site. However, the expertise for generating such bioengineered organs are limited and only very few centres are involved for investigating the potential use of such implants in clinical practice due to gap between the clinical transplant surgeons and basic scientists working on the concept evolution. Herein we discuss the recent advances and challenges to create functional secondary organs through intra-omental transplantation of ex vivo generated bioengineered humanized livers and their further application in the management of ESLD as a supportive bridge for organ transplantation.

Abstract
Background 5-Azacytidine (5-AZA), a DNA methyl transferase inhibitor, is a clinically used epigenetic drug for cancer therapy. Recently, we have shown that 5-AZA upregulates ten-eleven translocation (TET) protein expression in hepatocellular carcinoma (HCC) cells, which induce active demethylation. Vitamin C facilitates TET activity and enhances active demethylation. The aim of this study is to investigate whether vitamin C is able to enhance the effect of 5-AZA on active demethylation and to evaluate its consequence in HCC cell lines. Methods HCC cell lines (Huh7 and HLE) were treated with 5-AZA and vitamin C. After 48 h of treatment, viability (resazurin conversion), toxicity (lactose dehydrogenase (LDH) release), and proliferation ((proliferating cell nuclear antigen (PCNA)) of single- and combined-treated cells were assessed. The effect of the treatment on 5-hydroxymethylcytosine (5hmC) intensity (immunofluorescence (IF) staining), TET, Snail, GADD45B, and P21 mRNA (real-time PCR) and protein expression (Western blot) were investigated. Results Our results indicated that vitamin C enhances the anti-proliferative and apoptotic effect of 5-AZA in HCC cell lines. By further analyzing the events leading to cell cycle arrest, we have shown for the first time in HCC that the combination of 5-AZA and vitamin C leads to an enhanced downregulation of Snail expression, a key transcription factor governing epithelial-mesenchymal transition (EMT) process, and cell cycle arrest. Conclusions We conclude that when combined with 5-AZA, vitamin C enhances TET activity in HCC cells, leading to induction of active demethylation. An increase in P21 expression as a consequence of downregulation of Snail accompanied by the induction of GADD45B expression is the main mechanism leading to cell cycle arrest in HCCs.

Abstract
Aims/Introduction Diabetes is a major health concern throughout the world because of its increasing prevalence in epidemic proportions. β‐Cell deterioration in the pancreas is a crucial factor for the progression of diabetes mellitus. Therefore, the restoration of β‐cell mass and its function is of vital importance for the development of effective therapeutic strategies and most accessible cell sources for the treatment of diabetes mellitus. Materials and Methods Human fetuses (12–20 weeks gestation age) were used to isolate human hepatic progenitor cells (hHPCs) from fetal liver using a two‐step collagenase digestion method. Epithelial cell adhesion molecule‐positive (EpCAM+ve)‐enriched hHPCs were cultured in vitro and induced with 5–30 mmol/L concentration of glucose for 0–32 h. Pdx‐1 expression and insulin secretion was analyzed using immunophenotypic and chemifluorescence assays, respectively. Relative gene expression was quantified in induced hHPCs, and compared with uninduced and pancreatic cells to identify the activated transcription factors (Pdx‐1, Ngn‐3, Isl‐1, Pax‐4, Pax‐6 and Nkx‐6.1) involved in β‐cell production. Results EpCAM+ve cells derived from human fetal liver showed high in vitro trans‐differentiation potential towards the β‐cell phenotype with 23 mmol/L glucose induction after 24 h. The transcription factors showed eminent expression in induced cells. The expression level of transcription factors was found significantly high in 23 mmol/L‐induced hHPCs as compared with the uninduced cells. Conclusions The present study has shown an exciting new insight into β‐cell development from hHPCs trans‐differentiation. Relative quantification of gene expression in trans‐differentiated cells offers vast possibility for the production of a maximum number of functionally active pancreatic β‐cells for a future cure of diabetes.

Abstract
Bone marrow transplantation is a well-established stem cell-based therapy for the management of malignant and nonmalignant hematological disorders. In addition to the bone marrow, therapeutic hematopoietic stem cells (HSCs) can also be obtained from umbilical cord blood and mobilized peripheral blood. Transplantation of HSCs isolated from these tissues can be carried out with or without prior enrichment of specific cell types. New methodologies have been developed for lineage-specific HSC expansion and their transplantation as a supplementary treatment to whole bone marrow transplantation. In this review we have described the current methodologies for isolating and processing HSCs from various tissues, and discussed strategies to generate sufficient and functional HSCs for clinical and preclinical applications by expansion ex vivo. The various disease conditions in which these cells could be used, and the methods for delivering the cells into patients, are also discussed.

Abstract
Glucose dehydrogenase, a membrane bound enzyme oxidizing glucose to gluconic acid in the periplasmic space of Gram-negative bacteria plays a key role in mineral phosphate solubilization and is also an industrially important enzyme, being used as a glucose biosensor. A chimeric glucose dehydrogenase (ES chimera) encoding the N-terminal transmembrane domain from Escherichia coli and the C-terminal periplasmic domain from Serratia marcescens was constructed and the expression was studied on MacConkey glucose medium. The phosphate solubilizing ability of the chimeric GDH was also evaluated, substantiating the role of GDH in mineral phosphate solubilization (MPS). Four mutants of ES chimeric GDH were generated by site directed mutagenesis and the enzyme properties studied. Though the substrate affinity was unaltered for E742K and Y771M, the affinity of H775A and EYH/KMA to glucose and galactose decreased marginally and the affinity to maltose increased. Though Y771M showed a decreased GDH activity there was an increase in the heat tolerance. All the mutants showed an increase in the EDTA tolerance. The triple mutant EYH/KMA showed improved heat and EDTA tolerance and also an increase in affinity to maltose over the ES chimeric GDH.

Abstract
Glucose dehydrogenase (GDH) of Gram-negative bacteria is a membrane bound enzyme catalyzing the oxidation of glucose to gluconic acid and is involved in the solubilization of insoluble mineral phosphate complexes. A 2.4 kb glucose dehydrogenase gene (gcd) of Enterobacter asburiae sharing extensive homology to the gcd of other enterobacteriaceae members was cloned in a PCR-based directional genome walking approach and the expression confirmed in Escherichia coli YU423 on both MacConkey glucose agar and hydroxyapatite (HAP) containing media. Mineral phosphate solubilization by the cloned E. asburiae gcd was confirmed by the release of significant amount of phosphate in HAP containing liquid medium. gcd was over expressed in E. coli AT15 (gcd::cm) and the purified recombinant protein had a high affinity to glucose, and oxidized galactose and maltose with lower affinities.The enzyme was highly sensitive to heat and EDTA, and belonged to Type I, similar to GDH of E. coli.

Abstract
Twenty-three bacterial isolates were screened for their mineral phosphate-solubilizing (MPS) ability on Pikovskaya and National Botanical Research Institute's phosphate (NBRIP) agar. The majority of the isolates exhibited a strong ability to solubilize hydroxyapatite in both solid and liquid media. The solubilization in liquid medium corresponded with a decrease in the pH of the medium. Serratia marcescens GPS-5, known for its biocontrol of late leaf spot in groundnut, emerged as the best solubilizer. S. marcescens GPS-5 was subjected to ethyl methanesulfonate (EMS) mutagenesis, and a total of 1700 mutants, resulting after 45 minutes of exposure, were screened on buffered NBRIP medium for alterations in MPS ability compared with that of the wild type. Seven mutants with increased (increased-MPS mutants) and 6 mutants with decreased (decreased-MPS mutants) MPS ability were isolated. All seven increased-MPS mutants were efficient at solubilizing phosphate in both solid and liquid NBRIP medium. Among the increased-MPS mutants, EMS XVIII Sm-35 showed the maximum (40%) increase in the amount of phosphate released in liquid medium compared with wild-type S. marcescens GPS-5, therefore, it would be a useful microbial inoculant in groundnut cultivation. EMS III Sm W, a nonpigmented mutant, showed the lowest solubilization of phosphate among the 6 decreased-MPS mutants.
