Abstract ：
Electronic cigarette (e-Cig) has been promoted as a safer alternative to traditional cigarette (t-Cig) recently. However, there are limited scientific data on the potential health effects of e-Cig use. In this study, we evaluated the cytotoxicities of e-Cig and t-Cig condensate solutions (e-CigCS and t-CigCS) on human bronchial epithelial cells (16HBE cells) in vitro, and employed the exosome proteomic technique to systematically assess the effects of e-CigCS and t-CigCS on 16HBE cells. Cytotoxicity assay showed 16HBE cells were more sensitive to t-CigCS than e-CigCS. Proteomic analysis demonstrated that there are 431 differential expressed exosomal proteins (DEEPs) in test groups compared to the control air group (P-value<0.05) and t-CigCS has a greater influence than e-CigCS on exosomal protein expression. Bioinformatic analysis showed the DEEPs from the t-Cig group were significantly enriched in pathways in cancer while tobacco-flavored e-Cig (e-Cigt) and menthol-flavored e-Cig (e-Cigm) groups were not. Further validations of some DEEPs, such as NF-kappa B p65, Sulfiredoxin-1(SRXN1) and Thioredoxininteracting protein (TXNIP), were carried out using immunoblot and Real-time PCR analysis, showing that tCig may have a greater influence than e-Cig on tumor development and metastasis. Taken together, the finding reported here strongly support our hypothesis that electronic cigarettes are significantly less toxic compared with traditional cigarette.

Abstract ：
It remains technically challenging to develop a sensitive assay system to isothermally amplify the signal for miRNA detection because of its low abundance in tested sample, sequence similarities and existence in complex biological environments. In this study, using miRNA-21 as target model, a hairpin-inserted cross-shaped DNA nanoprobe (CP) with four functional arms is constructed for the ultrasensitive detection of miRNA via one-step built-in target analogue (BTA) cycle-mediated signal amplification. BTA is pre-locked in one arm of CP probe and inactive. In the presence of target miRNA, BTA can be unlocked and initiate an isothermal amplification process. Utilizing as-designed CP probe, miRNA-21 can be detected to down to 500 fM, and the linear response range spans over five orders of magnitude. The nonspecific signal is less than 1% upon nontarget miRNAs. CP probe exhibits ~six times enhancement in resistance to nuclease degradation and no obvious degradation-induced fluorescence change is detected during the assay period. The recovery yield ranges from 98.2~105.5% in FBS solution. Because of the high sensitivity, desirable specificity, strong anti-interference ability and substantial increase in nuclease resistance, CP probe is a promising tool for the detection of miRNAs in a complex biological milieu.

Abstract ：
MicroRNAs (miRNAs) are involved in a variety of biological processes, and the accurate detection of miRNAs is of great importance for early diagnosis of various cancers. Herein, we have developed a highly sensitive method for the intracellular imaging of miRNAs based on a palindromic probe-induced strand displacement amplification (pSDA). The sensing element is a partly complementary hybrid consisting of two DNA components: one fluorescent dye-labeled signaling probe containing a palindromic sequence and loop-based target recognition site and one quencher moiety-attached locking probe. In the presence of target miRNA, the target species can hybridize with the loop site and release the terminal palindromic fragment, initiating the pSDA reaction. Thus, a considerable amount of fluorescent moieties are spatially separated from the quenchers, generating a dramatically enhanced fluorescence signal. As a result, the target miRNAs can be quantified down to 25 pM with the linear response range over four orders of magnitude. The detection specificity is high enough to eliminate the interference from nontarget miRNAs and other biospecies co-existing in samples, and thus the diseased cells are easily distinguished from healthy cells. Strikingly, the pSDA-based system possesses the desirable capability to discriminate tumor cells from healthy cells, indicating a promising diagnostic tool for the detection of cancers and other diseases in early stage.

Abstract ：
Aberrant mitophagy has been implicated in a broad spectrum of disorders. PINK1, Parkin, and ubiquitin have pivotal roles in priming mitophagy. However, the entire regulatory landscape and the precise control mechanisms of mitophagy remain to be elucidated. Here, we uncover fundamental mitophagy regulation involving PINK1 and a non-canonical role of the mitochondrial Tu translation elongation factor (TUFm). The mitochondrion-cytosol dual-localized TUFm interacts with PINK1 biochemically and genetically, which is an evolutionarily conserved Parkin-independent route toward mitophagy. A PINK1-dependent TUFm phosphoswitch at Ser222 determines conversion from activating to suppressing mitophagy. PINK1 modulates differential translocation of TUFm because p-S222-TUFm is restricted predominantly to the cytosol, where it inhibits-mitophagy by impeding Atg5-Atg12 formation. The self-antagonizing feature of PINK1/TUFm is critical for the robustness of mitophagy regulation, achieved by the unique kinetic parameters of p-S222-TUFm, p-S65-ubiquitin, and their common kinase PINK1. Our findings provide new mechanistic insights into mitophagy and mitophagy-associated disorders.

Abstract ：
Herein, an autonomous table-tennis-motion-type DNA machine (ATT DNA machine) was proposed to integrate target recycling amplification (TRA) and triple strand-displacement amplification (T-SDA) into one signaling system for the efficient amplification detection of p53 gene. Firstly, X-shaped DNA duplex probe (XSP) was formed via the simple annealing of Probe A and Probe B. Upon addition of p53, the hybridization of p53 with Probe A results in the peeling of Probe B from XSP. Then, the primer binds to the Probe B to trigger a circular strand-displacement amplification, during which new primers are generated. Moreover, the newly-produced primers can in turn activate the target recycling amplification and triple strand-displacement amplification via bouncing back and forth between different Probe As and Probe Bs in a manner analogous to the table tennis motion. This newly-developed DNA machine can be used to detect p53 down to 0.5 pM with an excellent specificity, offering a 100-fold enhanced sensitivity compared to a non-amplification one-to-one hybridization based system. Moreover, this DNA machine is able to be applied for target analysis in complex environments. Additionally, the potential for practical applications is also verified, demonstrating a promising alternative tool for early diagnosis of cancers.

Abstract ：
Successful adhesion of circulating tumor cells (CTCs) to microvascular endothelium of distant metastatic tissue is the key starting step of metastatic cascade that could be effectively chemoprevented as we demonstrated previously. Here, we hypothesize that the hetero-adhesion may produce secretory biomarkers that may be important for both premetastatic diagnosis and chemoprevention. We show that co-incubation of triple-negative breast cancer (TNBC) cell line MDA-MB-231 with human pulmonary microvascular endothelial monolayers (HPMEC) secretes Cyr61 (CCN1), primarily from MDA-MB-231. However, addition of metapristone (RU486 metabolite) to the co-incubation system inhibits Cyr61 secretion probably via the Cyr61/integrin alpha v beta 1 signaling pathway without significant cytotoxicity on both MDA-MB-231 and HPMEC. Transfection of MDA-MB-231 with Cyr61-related recombinant plasmid or siRNA enhances or reduces Cyr61 expression, accordingly. The transfection significantly changes hetero-adhesion and migration of MDA-MB-231, and the changed bioactivities by overexpressed CYR61 could be antagonized by metapristone in vitro. Moreover, the circulating MDA-MB-231 develops lung metastasis in mice, which could be effectively prevented by oral metapristone without significant toxicity. The present study, for the first time, demonstrates that co-incubation of MDA-MB-231 with HPMEC secrets CYR61 probably via the CYR61/integrin alpha(v)beta(1) signaling pathway to promote adhesion-invasion of TNBC (early metastatic step). Metapristone, by interfering the adhesion-invasion process, prevents metastasis from happening.

Abstract ：
A perfect microenvironment facilitates the activated circulating tumor cells (CTCs) to spark the adhesion-invasion-extravasation metastatic cascade in their premetastatic niche. Platelet-CTC interaction contributes to the progression of tumor malignancy by protecting CTCs from shear stress and immunological assault, aiding CTCs entrapment in the capillary bed, enabling CTCs to successfully exit the bloodstream and enter the tissue, inducing epithelial-mesenchymal-like transition (EMT), and assisting in the establishment of metastatic foci. To prevent the cascade from sparking, we show that, the multifunctional S-nitrosocaptopril (CapNO) acts on both CTCs and platelets to interrupt platelet/CTCs interplay and adhesion to endothelium, thus inhibiting CTC-based pulmonary metastasis in vivo. The activated platelets cloak cancer HT29 cells, resulting in HT29-exhibiting platelet biomarkers CD61 and P-selectin positive. CapNO inhibits both sialyl Lewis(x) (Slex) expression on HT29 and ADP-induced activation of platelets through P-selectin- and GPIIb/IIIa-dependent mechanisms, confirmed by the corresponding antibody assay. CapNO inhibits platelet- or interleukin (IL)-1 beta-mediated adhesion between HT29 and endothelial cells, and micrometastatic formation in the lungs of immunocompetent syngeneic mouse models. CapNO have also shown the effects of vasodilation, anticoagulation, inhibition of matrix metalloproteinase-2 (MMP2) expression on cancer cells, and inhibition of cell adhesion molecules (CAMs) expression on vascular endothelium. Due to a series of the beneficial effects of CapNO, CTCs remain exposed to the hostile bloodstream environment and are vulnerable to death induced by shear stress and immune elimination. This new discovery provides a basis for CapNO used for cancer metastatic chemoprevention, and might suggest regulation of the CTCs bloodstream microenvironment as a new avenue for cancer metastatic prevention.
