AIM： To elucidate the mechanism of multidrug resistance in retinoblastoma, and to acquire more insights into in vivo drug ***： Three anticancer drug resistant Y79 human RB cells were generated against vincristine, etoposide or carboplatin, which are used for conventional chemotherapy in RB. Primary cultures from enucleated eyes after chemotherapy（PCNC） were also prepared. Their chemosensitivity to chemotherapeutic agents（vincristine, etoposide and carboplatin） were measured using MTT assay. Western blot analysis was performed to evaluate the expression of p53, Bcl-2 and various multidrug resistant proteins in retinoblastoma ***： Following exposure to chemotherapeutic drugs, PCNC showed less sensitivity to drugs. No significant changes observed in the p53 expression, whereas Bcl-2 expression was found to be increased in the drug resistant cells as well as in PCNC. Increased expression of P-glycoprotein（P-gp） was observed in drug resistant Y79 cells; however there was no significant change in the expression of P-gp found between primary cultures of primarily enucleated eyes and PCNC. Multidrug resistance protein 1（Mrp-1） expression was found to be elevated in the drug resistant Y79 cells as well as in PCNC. No significant change in the expression of lung resistance associatedprotein（Lrp） was observed in the drug resistant Y79 cells as well as in ***： Our results suggest that multidrug resistant proteins are intrinsically present in retinoblastoma which causes treatment failure in managing retinoblastoma with chemotherapy.

Asian Pacific Journal of Tropical Medicine 2018年第3期11卷 214-221页

作者： swati Gupta Kamla Prasad Mishra Paban Kumar Dash Manmohan Parida Lilly Ganju Shashi Bala singh Defence Institute of Physiology & Allied Sciences Defence Research and Development Establishment

Objective: To investigate the therapeutic efficacy of andrographolide, a plant derived compound, against chikungunya virus(CHIKV) infection. Methods: Using flow cytometry and immunoblotting assay, in vitro viral protein expression was studied in THP-1 cells line. In Balb/c mouse neonates, viral RNA copy number was determined by real time PCR. Results:The results showed reduced CHIKV protein expression on andrographolide treatment in CHIKV-infected human peripheral blood mononuclear cells, Vero cells and THP-I cell *** vivo, andrographolide treatment to CHIKV-infected neonates reduced viral RNA copy number. Further. andrographolide also increased cytotoxic T lymphocytes both in vitro and in vivo. Andrographolide also activated host innate immune pathways, viz., protein kinase *** eukaryotic initiation factor 2 α, retinoic acid inducible gene-Ⅰ and interferon regulatory factor 3/7, thereby increasing IFN-a secretion. CHIKV-induced nuclear factor κlight chain enhancer of activated B cells and tumor necrosis factor-a was also reduced on andrographolide treatment. Conclusion: Andrographolide inhibits CHIKV by suppressing viral protein expression and up-regulating host innate immunity and hence could be an effective therapeutic agent against CHIKV infection.

CellBio 2020年第3期9卷 123-141页

作者： swati Sharma Gurudutta U. Gangenahalli Upma singh Department of Pharmacology All India Institute of Medical Science (AIIMS) New Delhi India Stem Cell & Gene Therapy Research Group Institute of Nuclear Medicine & Allied Sciences New Delhi India Department of Applied Chemistry School of Vocational Studies & Applied Sciences Gautam Buddha University Greater Noida India

Hematopoietic stem cells (HSCs) are tissue-specific cells giving rise to all mature blood cell types regulated by a diverse group of hematopoietic cytokines and growth factors that influences the survival & proliferation of early progenitors and differentiation mechanisms by modulating the functional activities of HSCs. In this study, the functional yet distinctive role of three novel combinations of gene pairs RRAGC & PSMC2;CKAP4 & MANF;and CTR9 & CNTNAP2 have been newly identified. These novel combinations of genes were confirmed and expressed in K562 human leukemic cell line in the presence of cytokine combination (IL-3, FLT-3 and SCF) using RT-PCR and siRNA-mediated gene knock down strategy. This study signifies the synergistic role of gene pairs in different molecular activities like ubiquitination or proteasomal degradation, calcium mobilization, dopamine signaling.

Identification, occurrence, and validation of DRE and ABRE Cis-regulatory motifs in the promoter regions of genes of Arabidopsis thaliana

引用

Journal of Integrative Plant Biology 2014年第4期56卷 388-399页

作者： Sonal Mishra Aparna Shukla swati Upadhyay Sanchita Pooja Sharma Seema singh Ujjal J.Phukan Abha Meena Feroz Khan Vineeta Tripathi Rakesh Kumar Shukla Ashok Shrama Biotechnology Division CSIR-Central Institute of Medicinal and Aromatic Plants A Laboratory Under Council of Scientific and Industrial Research Metabolic and Structural Biology Division CSIR-Central Institute of Medicinal and Aromatic Plants A Laboratory Under Council of Scientific and Industrial Research Botany Department CSIR-Central Drug Research Institute (CSIR-CDRI)

Plants posses a complex co-regulatory network which helps them to elicit a response under diverse adverse conditions. We used an in silico approach to identify the genes with both DRE and ABRE motifs in their promoter regions in Arabidopsis thaliana. Our results showed that Arabidopsis contains a set of 2,052 genes with ABRE and DRE motifs in their promoter regions. Approximately 72~o or more of the total predicted 2,052 genes had a gap distance of less than 40o bp between DRE and ABRE motifs. For positional orientation of the DRE and ABRE motifs, we found that the DR form （one in direct and the other one in reverse orientation） was more prevalent than other forms. These predicted 2,o52 genes include 155 transcription factors. Using microarray data from The Arabidopsis Information Resource （TAIR） database, we present 44 transcription factors out of 155 which are upregulated by more than twofold in response to osmotic stress and ABA treatment. Fifty-one transcripts from the one predicted above were validated using semiquantitative expression analysis to support the microarray data in TAIR. Taken together, we report a set of genes containing both DRE and ABRE motifs in their promoter regions in A. thaliana, which can be useful to understand the role of ABA under osmotic stress condition.

Neurofibroma of the Pinna

引用

International Journal of Otolaryngology and Head & Neck Surgery 2014年第2期3卷 66-70页

作者： Satinder singh swati Tandon Asish Lahiri Shalabh Sharma Sir Ganga Ram Hospital Delhi India

Neurofibromas are relatively common lesions of the nervous system, but only a few cases involving the pinna have been reported. Isolated neurofibroma of pinna without neurofibromatosis has not been reported in the literature so far. Neurofibromas may develop anywhere in the body, including cranial and peripheral nerves. The type of impairment associated with neurofibromas depends largely on the site of the lesion. Cutaneous lesions, especially in the head and neck, generally cause deformity, whereas lesions that affect deeper systems (e.g., the auditory and ocular systems) are more likely to cause functional impairment. Usually found in individuals with neurofibromatosis, we report a case of neurofibroma of pinna in a patient without

印度勒克瑙城拥有丰富的历史文化遗产,许多建筑都可追溯到18世纪。本文介绍的这幢住宅位于该市繁忙的主干道边,是一片私人住宅地块的边缘部分。项目采用了印度传统四合院的建筑形制,以回应城市特征和炎热的气候条件。业主希望在这个两层高的通风庭院中穿插设置一些有遮挡的开放式露台和景观花园。同时,除了6间卧室之外,还需要普伽室、书房、影视室以及多功能区域等,并希望这些空间均能通往露台和景观花园。
