Information regarding both of the major forms of this disease, adenocarcinoma and squamous cell carcinoma, has accumulated in conjunction with data on precursor conditions such as Barrett’s esophagus. Interesting and promising ?ndings have included overexpression of proto-oncogenes, loss of heterozygosity at multiple chromosomal loci, tumor suppressor gene inactivation, epigenetic silenc- ing by DNA methylation, and mutations and deletions involving the tumor suppressor gene p53. Important cancer pathways, the cyclin kinase inhibitor cascade and the DNA mismatch repair process, implicated in the genesis of multiple tumor types have also been inculpated in esophageal carcinogenesis. Alterations in the p16 and p15 cyclin kinase inhibitors including point mutations and homozygous deletions have been reported in primary esophageal tumors. Further developments in the ?eld of molecular carcinogen- esis of esophageal malignancies promise to yield improvements in prevention, early detection, prognostic categorization, and perhaps gene-based therapy of this deadly disease.展开更多

This review mainly focuses on the molecular biology of many cytokines （including growth factors） and other molecular factors such as extracellular matrix （ECM） on wound healing. The molecular biology in cell movement such as epidermal cells in wound healing was also discussed. Moreover many common chronic wounds such as pressure ulcers, leg ulcers, diabetic foot wounds, venous stasis ulcers, etc. usually deteriorate into non-healing wounds. Therefore the molecular biology such as advanced glycation end products （AGEs） and other molecular factors in diabetes non-healing wounds were also reviewed.展开更多

Research on rhizosphere microbes of various medicinal plants is essential for microbial ecology, applied microbiology and industrial biotechnology with regard to the sustainable utilization of Chinese medicinal resources. However, the inability of culturing most rhizosphere microorganisms （around 99%） in the laboratory obviates the research progress. In recent years, there is enormous advances in applying non-culturing techniques based on molecular biology and omics to the study of rhizosphere microbial diversity and plant-microbe interactions. DGGE, T-RFLP, ARDRA, DNA cloning and Sanger sequencing are still useful in the rhizosphere studies, while various omics tools, such as FISH, SIP, microarray, next generation sequencing （NGS）, etc., evolve quickly to provide more comprehensive understanding of the rhizosphere microbiota and microbiome. Flexible applications of NGS technologies are here exemplified, e.g., amplicon sequencing, metagenomic sequencing, whole genome sequencing, and transcriptome sequencing, which address the biology and biotechnology potentials of the rhizosphere microbiome of medicinal plants. This review discusses recent findings and future challenges in the study of rhizosphere microbes, highlighting medicinal plant rhizosphere study, evolution of research methods, and innovative combinations of novel high-throughput techniques. The top-down approaches such as metagenomics and bottom-up approaches targeting individual species or strains should be integrated and combined with modeling approaches to afford a wide-ranging understanding of the microbial community as a whole.展开更多

However, the uncontrolled spread of GMOs may lead to genetic contamination by horizontal gene transfer, resulting in unpredictable biosafety risks. To deal with these challenges, many effective methods have been developed for biocontainment. In this article, we summarize and discuss recent advances in biocontainment strategies from three aspects: DNA replication, transcriptional regulation, and protein translation. We also briefly introduce the efforts in the biocontainment convention, such as the recent publication of the Tianjin Biosecurity Guidelines for the Code of Conduct for Scientists.展开更多

The tr...Cardiovascular disease（CVD） is a common and serious disease in the elderly, which has characteristically high prevalence, disability, and mortality rates. However, the etiology of CVD is still not very clear. The traditional Mongolian medicine Sugemule-3（SM） is usually used for the treatment of CVD and exhibits a good curative effect. In this study, a sentm metabolite profile analysis was used to identify potential biomarkers associated with isoprote- renol（ISO）-induced CVD and investigate the mechanism of the action of SM. Ultra-perfornlance liquid chromato- graphy coupled with quadrupole time-of-flight mass spectrometry（UPLC-Q-TOF-MS） was used for the metabono- mics analysis. Principal component analysis（PCA） was used to process the acquired data to differentiate the results of the control, CVD, and SM treatment groups. Orthogonal partial least squares discriminant analysis（OPLS-DA） enabled the identification of 21 metabolites as potential biomarkers that were relevant to phospholipid and energy metabolism. The results indicate that SM played a protective role against ISO-induced CVD in rats by regulating phospholipid and energy metabolic pathways. Fttrther, we verified the apoptotic metabolic pathway using molecular biology methods, such as terminal deoxynucleotidyl transferase（TdT） deoxyuridine 5＇-triphosphate（dUTP） nick-end labeling（TUNEL） assay and Western blot analysis. Furthermore, this study identified early biomarkers of CVD and elucidated the underlying mechanism of the therapeutic actions of SM, which is worth further to be investigated for development as a clinical therapy.展开更多

The complexities of diagnosing and treating these disorders emphasize the need for objective, quantitative data to improve diagnostic accuracy and treatment efficacy. This study aims to explore the genetic underpinnings of neuropsychiatric diseases, contrasting them with well-characterized diseases like breast cancer, and discuss the role of specific genetic mutations and their implications for personalized treatment. The paper delves into the genetic and molecular insights of neuropsychiatric diseases, examining the role of specific genetic mutations and the potential for gene editing technologies like CRISPR. It contrasts the genetic underpinnings of neuropsychiatric diseases with well-characterized diseases like breast cancer, highlighting the potential for a shift towards molecular and genetic-based diagnostics and treatments. The study argues that a shift towards molecular and genetic-based diagnostics and treatments could revolutionize our approach to neuropsychiatric diseases, much like how biomarker tests have transformed breast cancer treatment. It concludes by advocating for a more personalized approach to healthcare, tailored to an individual’s unique genetic makeup, as the future of neuropsychiatric disease diagnosis and treatment.展开更多
