Epidemiology of EGFR Mutation in Adenocarcinoma NSCLC Patients in India: A Systematic Review and Meta-Analysis

引用

Advances in Lung Cancer 2024年第1期13卷 1-21页

作者： ankita Jain Kumar Prabhash Venkatraman Radhakrishnan Shashank Srinivasan Pfizer Products India Private Limited Mumbai India Tata Memorial Hospital Mumbai India Cancer Institute (W.I.A.) Chennai India

Studies reporting the Indian prevalence of Epidermal Growth Factor Receptor (EGFR) mutation are mostly single centers with small sample sizes. This systematic review and meta-analysis summarized the available evidence of EGFR mutation epidemiology in Indian patients with adenocarcinoma (ADC) Non-Small Cell Lung Cancer (NSCLC). We conducted a structured literature search in PubMed, and EMBASE databases from January 2004 through October 2019. The primary outcome of interest was prevalence of EGFR mutation by gender, smoking status, and mutation subtype. The review included 34 studies. EGFR mutation prevalence was 39.5% in patients with ADC, and significantly higher in females, non-smokers, and patients with exon 19 deletions. The EGFR mutation frequency in Indian patients with ADC was higher than reported in Caucasians but at a lower range of that reported in East Asians. These findings support the use of EGFR mutation testing to guide choice of treatment.

cis-trans Engineering： Advances and Perspectives on Customized Transcriptional Regulation in Plants

引用

Molecular Plant 2018年第7期11卷 886-898页

作者： ankita Shrestha Ahamed Khan Nrisingha Dey Division of Microbial and Plant Biotechnology Institute of Life Sciences Department of Biotechnology Government of India Chandrasekharpur Bhubaneswar Odisha India These authors contributed equally to this article.

Coordinated transcriptional control employing synthetic promoters and transcription factors （TFs） can be used to achieve customized regulation of gene expression in planta. Synthetic promoter technology has yielded a series of promoters with modified cis-regulatory elements that provide useful tools for efficient modulation of gene expression. In addition, the use of zinc fingers （ZFs）, transcription activator-like effectors （TALEs）, and catalytically inactive clustered regularly interspaced short palindromic repeats （CRISPR）-associated protein 9 （dCas9） has made it feasible to engineer TFs that can produce targeted gene expression regulation; these approaches are particularly effective when artificial TFs are coupled with transcriptional activators or repressors. This review focuses on strategies used to engineer both promoters and TFs in the context of targeted transcriptional regulation. We also discuss the creation of synthetic inducible platforms, which can be used to impart stress tolerance to plants. We propose that combinatorial ＂cis-trans engineering＂ using a CRISPR-dCas9-based bipartite module could be used to regulate the expression of multiple target genes. This approach provides an attractive tool for introduction of specific qualitative traits into plants, thus enhancing their overall environmental adaptability.
