讲座内容:

Cancer is a leading cause of death worldwide. Protein kinase CK2, a serine-threonine kinase, is overexpressed in many human cancers, and most often overexpression is associated with worse prognosis. CK2 is a ubiquitously expressed and constitutive activated, which is considered the most pleiotropic protein kinase in the human kinome. The predominant roles of CK2 are stimulating cell growth and prevention of apoptosis.

Over the last decade, expression levels of CK2 are associated with CK2 pathological functions in human tumors. Basic and translational studies have provided evidence of CK2 as a pivotal molecule driving the growth of many cancers, including solid tumors and blood malignancies. As a key regulator of signaling networks, CK2 could induce the activation of JAK/STAT, NF-kB and AKT-mTOR pathways, which are critical for cell proliferation, survival and drug resistance. CK2 also is an oncogene can synergize with known oncogenes, such as RAS during tumorigenesis.

Here, I reported that the expression levels of CK2 subunits in human tumor tissues using the database Oncomine. In addition, the correlation between CK2 expression and overall survival using the Kaplan-Meier Plotter database also discussed. Furthermore, the therapeutic effects of CK2 inhibitors in cancer growth, specifically the CX4945, was discussed. All these findings from these studies suggest that CK2 is a valuable therapeutic target in solid tumors and leukemias. The initiation of clinical trials shown success on using CK2 inhibitors in cancer patients. We conclude that the CK2 inhibitors are novel therapeutic strategies for treating cancer patients.

As such, the more detailed investigations on CK2 as a cancer biomarker for diagnosis and prediction of progression and as a novel target for cancer therapy are needed in cancer research.

讲座内容:

Targeted therapy is an effective strategy for precision medicine in cancer treatment. The conventional cancer chemotherapeutic agents which are still widely used in clinic is lack of the selectivity and specificity, resulting in narrow safety profiles and toxicity to normal organs. The ADCs made a successful application recently, more than ten ADCs have been used in clinic for different types of cancers and dozens of more ADCs are under clinical investigations. However, ADCs face the problems of low drug-loading capacity, limitation of the ability to extravasate and penetrate deep into a solid tumor mass, and toxicity caused by the continuous premature drug cleavage etc. Alternatively, the replacement of the mAb in ADCs with small molecule targeting ligands leads to the development of small molecule-drug conjugates (SMDCs) that have the potential to overcome the disadvantages of ADCs. Moreover, SMDCs with multifuntional properties could not only keep tumor targeting but also might reduce the tumor metastasis which is the main reason of death caused by cancer.  E-selectin plays an essential role in the early stage of metastasis, it can recognize some carbohydrate structure on the surface of tumor cells and mediate the adhesion between cancer cells and the endothelial cells, which is the first step of tumor migaration.  We use a specific E-selectin ligand for development of new multifunctional SMDCs that are based on a  ternary conjugate of PEG, peptide CIELLQAR (8CR) and the hydrophobic anticancer drugs. The peptide is an E-selectin ligand, which is used for targeting activated tumor vasculature and inhibiting metastasis, besides, this kind of drug delivery system could form nanosized micelles in aqueous solution, leading to a significantly improved antitumor response and metastasis inhibition. This SMDCs possess the following characteristics: 1) passive tumor targeting induced by EPR effect of the nanoparticles and actively target the tumor angiogenesis with specific peptide ligands, 2) multi-antitumor effects at the same time, including inhibition of tumor angiogenesis, inhibition of tumor cells growth adjacent to tumor vasculature and inhibition of tumor metastasis.

讲座内容:

Traditional plasmonic materials mainly composed of noble metal nanostructures, which has been of great importance in creating high-performance biochemical sensors due to its sensitivity to changes in the surrounding medium and the generation of resonantly enhanced nanoscale light fields. However, the fixed and relatively large free charge concentrations in these noble metals result in great damping losses and prohibit its potential implementation in future on-chip plasmonic sensing systems. More importantly, their sensitivities are only limited to the biochemical events which induce significant change of the ambient refractive-index. It is beyond its capability for many others which are mostly charge-transfer-mediated. Degenerately doped semiconductors are an emerging class of plasmonic materials for which plasmonic features can be controlled by the concentration of dopants in the crystal structure. This unique feature can offer new dimensions for plasmonic biochemical sensing by allowing charge-based detection. In this seminar, I will introduce a new class of tunable plasmonic materials based on either sub-stoichiometric or heavily doped two-dimensional (2D) molybdenum oxides. Due to their capabilities for accommodating a large number of vacancies and ions, their plasmonic properties can be tuned across the whole visible spectrum and the near-red end of the NIR region, which are more viable for commercial applications than other doped semiconductors. Furthermore, through the demonstration of a few representative biochemical sensing models, the sensitivities of these materials are impressive as the structural vacancies and inserted dopants are facilely exchanged from the 2D planar host during biochemical events, providing an unprecedented opportunity in developing high performance biochemical sensors.

讲座内容:

Biomedical optical imaging is an important subdivision of optical imaging to understand the anatomy and function of life. In principle, biomedical optical imaging systems form an image by manipulating the excitation light and detecting the signals originating from light and tissue interactions. Ever since the invention of the first optical microscope over 1000 years ago, biomedical optical imaging technologies have been steadily evolving to enable faster, deeper, and higher resolution imaging. These technologies have led to a more comprehensive understanding of life at the macro-, micro-, and nanoscales and have improved clinical diagnosis and treatment.

This seminar focuses on three optics-based biomedical imaging, specifically photoacoustic computed tomography, light-field fluorescence imaging, and trans-illumination imaging. For photoacoustic computed tomography, the seminar will cover high-speed, high-resolution photoacoustic imaging systems, and their applications in structural imaging of human blood vessels and functional imaging of animal intestines. For light-field fluorescence imaging, the seminar will talk about high- and super-resolution light field microscopies and their performance in imaging large-scale neural activity of zebrafish labeled with calcium indicator. For Trans-illumination imaging, the seminar will present a multi-color and dual-mode system for intestinal imaging of free-moving mice. Each of the three modalities has extended our understanding of life science.

讲座内容:

Nucleic acids are natural biopolymers of nucleotides, which carry genetic information and play central roles in cell growth and development. Nucleic acids always present significant differences among individual cells, which can’t be obtained from populations of cells. Single-cell nucleic acids analysis can reveal cell heterogeneity, which is of great significance for life science research and diagnosis of serious diseases. This report will focus on the key scientific issues such as low abundance, numerous in variety, discrimination between homologous sequences, recognition of base modification and spatial proximity of intracellular nucleic acids. A brief summary of our recent development will be provided. 1) single-nucleotide discrimination and multiplex homologous sequences detection in living cells with high sensitivity; 2) quantification of various chemical modifications of nucleic acids in single cells by DNA-encoded amplification with an extended strategy for other characteristics of nucleic acid besides sequences; 3) imaging of molecular organization and proximity in single-cell nanoenvironment with variable resolution and precision.

讲座内容:

Many Studies have shown that cells in living organisms can generate various biological responses to external mechanical stimuli, and change intracellular biomechanical signals due to biological alterations arising from physiological or pathological causes as well. The use of cellular mechanical information as a "biomarker" to reflect the biological state of cells and to achieve label-free cell classification and sorting for disease diagnosis and drug screening has gradually become a frontier topic in mechanobiology and mechanomedicine field. To this end, a deep interdisciplinary cross and technology integration, including biology, mechanics, materials, image processing, optoelectronic engineering, artificial intelligence, and microfluidic biochips, is required. This talk will first introduce some basic concepts and ideas of cellular mechanobioinformatics, followed by some of our recent research advances, including: 1) High-throughput cell traction force microscopy (TFM) techniques that can quantitatively characterize cell-substrate mechanics interaction information; 2) Applications of TFM in mechanomedicine, such as lymphocyte mechano-activation and cardiotoxicity testing based on cardiomyocyte contractility; 3) Electrodeformation chip based on DEP force for quantifying global viscoelasticity of cells. 4) Applications of DEP chip in cancer diagnosis, drug evaluation, etc.

讲座内容

Cancer therapy based on reactive oxygen species (ROS)-generation strategies has gained great momentum in recent years. Radiotherapy (RT), referring to external-beam X-ray irradiation hereafter, has gained acceptance for treating over 50% cancer patients in clinic. Unfortunately, the effectiveness of RT is largely compromised due to the heterogeneous radiation responses and radioresistance which vary in different cancer types and among individuals. Recent studies revealed that the acute inflammatory response aroused by RT is responsible to the adaptive immune responses through ROS-mediated cell apoptosis and the ensuing activation of immune system1.Therefore, we hypothesized that the ROS generation from radiation-induced acute inflammation may serve as a molecular target for early stratification of the RT outcomes in cancer therapy. We then designed a magnetic resonance molecular imaging probe to quantify the inflammatory ROS and stratify the RT response in a mouse 4T1 tumor model. The results showed that the T1 relaxation time changes at 24-48 h post RT had strong correlations with the ensuing adaptive immune responses at day 5 (Pearson’s R2 = 0.9664)  and the tumor inhibition rates at day 18 (Pearson’s R2 = 0.8663) after RT, respectively2. This study provides an insight to early stratify RT response targeting the acute inflammatory ROS level, which may shed new light on cancer diagnosis, prognosis and treatment planning for precision cancer therapy.

讲座内容:

Inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis, are chronic relapsing disorders of the gastrointestinal tract. Characterized pathologically by intestinal inflammation and epithelial injury, great challenges exist for the treatment of IBD due to its complicated etiology and incurable nature. Traditional strategies rely on frequent and long-term administration of high dosages of anti-inflammatory drugs, which inevitably cause side effects. Therefore, novel therapeutic methods and drug delivery systems capable of improving therapeutic effect while simultaneously decreasing side effects need to be developed. The emergence of nanotechnology provides alternative approaches for diagnosis and treatment of IBD, as nanoparticles (NPs) have unique physicochemical properties such as targeting to the site of inflammation and the ability to alter the pharmacokinetics of traditional drugs.

Nanoparticles-based drug delivery systems for IBD which developed in our team will be given. Challenges and prospects in the field will be proposed to promote the development of targeted drug delivery for IBD treatment.

讲座内容:

Using soft materials (e.g., paper, hydrogel) to replace the traditional hard materials (e.g., glass, silicon) as substrates have become a recent trend in developing point-of-care testing (POCT) platforms. And through integration of the soft materials with electrochemical or electric devices can further extend the applications of POCT. In our recent work, we used four kinds of soft materials, including paper, PDMS, hydrogel and liquid marble, as the new soft substrates of POCT platforms and realized their new applications in POCT. For example, by integration of the electrodes and hydrophobic channels on paper through simply writing method using home-made pens, the fabricated paper-based electrochemical devices have been successfully applied to detect glucose in artificial urine and melamine in sample solutions. By fabrication of MWNTs/PDMS fibers as multifunctional sensors and integration them on a glove, the measurement of gesture recognition and temperature have been realized by the “smart” glove. Through injection of liquid metal into the 3D helical structure of hydrogel and combination the hydrogel with electronic sensing device, the temperature, UV sensing and EMG signal detections have been performed by the wearable, multifunctional hydrogel device. By using liquid marble asa separator and small device for isoelectric focusing, the POCT separation and analysis of proteins have been realized. The proposed new soft platforms show wide application potential in POCT.

讲座内容:

Drug detection in biofluids has always been great importance for clinical diagnosis. Many detection technologies such as chromatography-mass spectrometry, have been applied to the detection of drugs. However, these technologies required multi-step operations, including complicated and time-consuming pretreatment processes and operations of bulky detection instruments, significantly limiting development of drug detection in clinical diagnosis. Herein, a portable 3D-printed paper cartridge was fabricated for fast sample preconcentration and direct drugs quantitative detection in biofluids by a portable Raman spectrometer. This cartridge contained both paper tip with silver nanowires to preconcentrate samples and achieve surface-enhanced Raman Scattering (SERS) measurement, and 3D-printed cartridge to build enclosed environment for the improvement of detection, which cost only one dollar. The preconcentration ability of the cartridge was up to 18.13-fold fluorescence enhancement and compared to the non-preconcentration method, it achieved 9.93-fold improvement of SERS performance. The anticancer drug of epirubicin hydrochloride, cyclophosphamide and their mixtures were quantitatively detected in the bovine serum or artificial urine. The integrated detection procedure required only 1 h, including sample pretreatment and preconcentration, drying, SERS measurements, and quantification analysis. This 3D-printed paper cartridge constituted a portable detection platform that would be potentially a practical and point-of-care detection tool for drug preconcentration and quantification on the clinical diagnosis.
