[PMID: 38522238 DOI: 10.1016/j.biopha.2024.116431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 03/05/2024] [Accepted: 03/15/2024] [Indexed: 03/26/2024] Open
Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive and life-threatening lung disease with high mortality rates. The limited availability of effective drugs for IPF treatment, coupled with concerns regarding adverse effects and restricted responsiveness, underscores the need for alternative approaches. Kefir peptides (KPs) have demonstrated antioxidative, anti-inflammatory, and antifibrotic properties, along with the capability to modulate gut microbiota. This study aims to investigate the impact of KPs on bleomycin-induced pulmonary fibrosis. METHODS Mice were treated with KPs for four days, followed by intratracheal injection of bleomycin for 21 days. Comprehensive assessments included pulmonary functional tests, micro-computed tomography (µ-CT), in vivo image analysis using MMPsense750, evaluation of inflammation- and fibrosis-related gene expression in lung tissue, and histopathological examinations. Furthermore, a detailed investigation of the gut microbiota community was performed using full-length 16 S rRNA sequencing in control mice, bleomycin-induced fibrotic mice, and KPs-pretreated fibrotic mice. RESULTS In KPs-pretreated bleomycin-induced lung fibrotic mice, notable outcomes included the absence of significant bodyweight loss, enhanced pulmonary functions, restored lung tissue architecture, and diminished thickening of inter-alveolar septa, as elucidated by morphological and histopathological analyses. Concurrently, a reduction in the expression levels of oxidative biomarkers, inflammatory factors, and fibrotic indicators was observed. Moreover, 16 S rRNA sequencing demonstrated that KPs pretreatment induced alterations in the relative abundances of gut microbiota, notably affecting Barnesiella_intestinihominis, Kineothrix_alysoides, and Clostridium_viride. CONCLUSIONS Kefir peptides exerted preventive effects, protecting mice against bleomycin-induced lung oxidative stress, inflammation, and fibrosis. These effects are likely linked to modifications in the gut microbiota community. The findings highlight the therapeutic potential of KPs in mitigating pulmonary fibrosis and advocate for additional exploration in clinical settings.

Abstract
Matrix metalloproteinase-2 (MMP2) is a zinc-dependent endopeptidase and a promising target for various diseases, including cancer and fibrosis. Herein, we report the discovery of a novel MMP2-selective inhibitor with high chemical stability and slow tight-binding features. Based on the degradation mechanism of our small-molecule-peptide hybrid 1, the tripeptide linker {5-aminopentanoic acid [Ape(5)]-Glu-Asp} of 1 was replaced by a shorter linker (γ-D-Glu). Phenylbenzamide was suitable for the new generation of MMP2 inhibitors as an S1' pocket-binding group. The introduction of (4S)-aminoproline dramatically increased the chemical stability while maintaining high subtype selectivity because of its interaction with Glu130. TP0597850 (18) exhibited high stability over a wide range of pH values as well as potent MMP2 inhibition (Ki = 0.034 nM) and ≥2000-fold selectivity determined using the inhibition constants. A kinetic analysis revealed that it possesses slow tight-binding nature with a long MMP2 dissociative half-life (t1/2 = 265 min).

Hyaluronidase responsive second near-infrared fluorescent nanocomplex for combined HER2 blockade and chemotherapy of HER2+ breast cancer. BIOMATERIALS ADVANCES 2022; 141:213115. [PMID: 36115156 DOI: 10.1016/j.bioadv.2022.213115] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 08/22/2022] [Accepted: 09/07/2022] [Indexed: 06/15/2023]
Abstract
The human epidermal growth factor receptor-2-positive (HER2+) type is aggressive and has poor prognosis. Although anti-HER2 therapy alone or in combination with other treatment regimens showed significant improvement in survival outcomes, breast cancer patients are still suffering from tumor relapse and severe dose-limiting side effects. Thus, there is still an unmet challenge to develop effective therapeutic agents for HER2+ breast cancer treatment with minimized side effects. Herein, we produced a stimuli-responsive and tumor-targeted hyaluronic acid (HA) nanocomplex that combined HER2 blockade and chemotherapy for effective HER2+ breast cancer therapy. A hydrophobic NIR-II dye, IR1048, was covalently linked with HA to form a spherical HA-IR1048 nanoparticle (HINP), with Herceptin conjugated on the surface and paclitaxel (PTX) encapsulated inside. The fluorescent signals from the yielding Her-HINP/PTX are quenched originally, but a strong NIR-II signal is generated when HINP is degraded by the hyaluronidase that is overexpressed in breast tumors, thus allowing the tracking and visualization of Herceptin and PTX accumulation. Her-HINP/PTX peaked in HER2+ tumors at 24 h post injection as imaged by NIR-II fluorescent imaging. A significantly improved tumor growth inhibition effect was observed after five systemic treatments compared to single PTX (3.71 ± 0.41 times) or Herceptin (5.98 ± 0.51 times) treatment in a HER2-overexpressed breast cancer mouse model with prolonged survival. Collectively, the designed Her-HINP/PTX presents a new hyaluronidase-responsive and HER2 blockade nanoformulation that can visualize the accumulation of nanocomplexes and release drugs inside tumors for combined HER2+ breast cancer therapy with a great promise for translational study. STATEMENT OF SIGNIFICANCE: The high expressions of a protein called human epidermal growth factor receptor 2 (HER2) in breast tumors make this subtype of cancer aggressive. Currently, chemotherapy combined with a HER2 antibody, Herceptin, is a preferred approach for HER2-positive breast cancer therapy. However, these breast cancer patients still suffer from tumor relapse and severe side effects because various therapeutic agents have inherent different biodistributions, resulting in insufficient treatment effects and unfavorable normal organ uptake of these therapeutic agents. Herein, we produced a nanocomplex carrying both Herceptin and chemotherapy drug to simultaneously deliver two drugs into tumors for efficient HER2+ tumor treatment with minimized side effects, providing new insights for designing a combined therapy strategy.

Abstract
Matrix metalloproteinase-2 (MMP2) is a zinc-dependent endopeptidase that plays important roles in the degradation of extracellular matrix proteins. MMP2 is considered to be an attractive target for the treatment of various diseases such as cancer, arthritis, and fibrosis. In this study, we have developed a novel class of MMP2-selective inhibitors by hybridizing the peptide that binds to a zinc ion and S2-S5 pockets with small molecules that bind to the S1' pocket. Structural modifications based on X-ray crystallography revealed that the introduction of 2,4-diaminobutanoic acid (Dab) at position 4 dramatically enhanced MMP2 selectivity by forming an electrostatic interaction with Glu130. After improving the metabolic and chemical stability, TP0556351 (9) was identified. It exhibited potent MMP2 inhibitory activity (IC50 = 0.20 nM) and extremely high selectivity. It suppressed the accumulation of collagen in a bleomycin-induced idiopathic pulmonary fibrosis model in mice, demonstrating the efficacy of MMP2-selective inhibitors for fibrosis.

Abstract
α-Mangostin is a xanthone natural product isolated as a secondary metabolite from the mangosteen tree. It has attracted a great deal of attention due to its wide-ranging effects on certain biological activity, such as apoptosis, tumorigenesis, proliferation, metastasis, inflammation, oxidation, bacterial growth and metabolism. This review focuses on the key pathways directly affected by α-mangostin and how this varies between disease states. Insight is also provided, where investigated, into the key structural features of α-mangostin that produce these biological effects. The review then sheds light on the utility of α-mangostin as a investigational tool for certain diseases and demonstrate how future derivatives may increase selectivity and potency for specific disease states.

Abstract
For drug-induced interstitial lung disease (DIILD) translational imaging biomarkers are needed to improve detection and management of lung injury and drug-toxicity. Literature was reviewed on animal models in which in vivo imaging was used to detect and assess lung lesions that resembled pathological changes found in DIILD, such as inflammation and fibrosis. A systematic search was carried out using three databases with key words “Animal models”, “Imaging”, “Lung disease”, and “Drugs”. A total of 5749 articles were found, and, based on inclusion criteria, 284 papers were selected for final data extraction, resulting in 182 out of the 284 papers, based on eligibility. Twelve different animal species occurred and nine various imaging modalities were used, with two-thirds of the studies being longitudinal. The inducing agents and exposure (dose and duration) differed from non-physiological to clinically relevant doses. The majority of studies reported other biomarkers and/or histological confirmation of the imaging results. Summary of radiotracers and examples of imaging biomarkers were summarized, and the types of animal models and the most used imaging modalities and applications are discussed in this review. Pathologies resembling DIILD, such as inflammation and fibrosis, were described in many papers, but only a few explicitly addressed drug-induced toxicity experiments.

Abstract
Fluorescence molecular imaging (MI) is an important concept in preclinical research that focuses on the visualization of cellular and biological function in a non-invasive fashion to better understand in vivo disease processes and treatment effects. MI differs fundamentally from traditional preclinical imaging strategies in that it generally relies on reporter probes specific for particular targets or pathways that can be used to reveal biological changes in situ, at the site(s) of disease. In contrast, the more established imaging modalities, like magnetic resonance imaging, X-ray, micro X-ray computed tomography, and ultrasound, historically have relied primarily on late-stage anatomical or physiologic changes. The practical application of fluorescence MI, however, has drifted somewhat from the emphasis on quantifying biology, and based on the publication record, it now appears to include any imaging in which a probe or contrast agent is used to non-invasively acquire in vivo endpoint information. Unfortunately, the mere use of a defined biologically specific probe, in the absence of careful study design, does not guarantee that any useful biological information is actually gained, although often useful endpoint results still can be achieved. This review proposes to add subcategories of MI, termed MI biological assessment (or MIBA), that emphasize a focus on obtaining early and clear biological changes associated with disease development, therapeutic efficacy, and drug-induced tissue changes. Proper selection of probes and careful study design are critical for maximizing the non-invasive assessment of in vivo biological changes, and applications of these critical elements are described.

Abstract
Abstract Integrin αvβ6 is expressed at an undetectable level in normal tissues, but is remarkably upregulated during many pathological processes, especially in cancer and fibrosis. Noninvasive imaging of integrin αvβ6 expression using a radiotracer with favorable in vivo pharmacokinetics would facilitate disease diagnosis and therapy monitoring. Through disulfide-cyclized method, we synthesized in this study, a new integrin αvβ6-targeted cyclic peptide (denoted as cHK), and radiolabeled it with 99mTc. The ability of the resulting radiotracer 99mTc–HYNIC–cHK to detect integrin αvβ6 expression in pancreatic cancer xenografts and idiopathic pulmonary fibrosis was evaluated using small-animal single-photon emission computed tomography (SPECT)/computed tomography (CT). 99mTc–HYNIC–cHK showed significantly improved in vivo metabolic stability compared to the linear peptide-based radiotracer 99mTc–HYNIC–HK. 99mTc–HYNIC–cHK exhibited similar biodistribution properties to 99mTc–HYNIC–HK, but the tumor-to-muscle ratio was significantly increased (2.99 ± 0.87 vs. 1.82 ± 0.27, P < 0.05). High-contrast images of integrin αvβ6-positive tumors and bleomycin-induced fibrotic lungs were obtained by SPECT/CT imaging using 99mTc–HYNIC–cHK. Overall, our studies demonstrate that 99mTc–HYNIC–cHK is a promising SPECT radiotracer for the noninvasive imaging of integrin αvβ6 in living subjects. Graphical Abstract ![]()

Abstract
The composition and mechanical properties of the extracellular matrix are dramatically altered during the development and progression of pulmonary fibrosis. Recent evidence indicates that these changes in matrix composition and mechanics are not only end-results of fibrotic remodeling, but active participants in driving disease progression. These insights have stimulated interest in identifying the components and physical aspects of the matrix that contribute to cell activation and disease initiation and progression. This review summarizes current knowledge regarding the biomechanics and dynamics of the ECM in mouse models and human IPF, and discusses how matrix mechanical and compositional changes might be non-invasively assessed, therapeutically targeted, and biologically restored to resolve fibrosis.

Abstract
Silicosis is an irreversible lung disease resulting from long-term inhalation of occupational dust containing silicon dioxide. However, the pathogenesis of silicosis has not been clearly understood yet. Accumulating evidence suggests that miR-29 may have a significant anti-fibrotic capacity, meanwhile it may relate to Wnt/β-catenin pathway. The purpose of this study was to discuss the role of miR-29 in the progression of silicosis. A lentiviral vector was constructed, named Lv-miR-29c, which was overexpressing miR-29c. In vivo, intratracheal treatment with Lv-miR-29c significantly increased expression of miR-29c, and reduced expression of β-catenin, matrix metalloproteinase (MMP)-2, and MMP-9 in the lung and levels of transforming growth factor-beta 1 (TGF-β1) and interleukin-6 (IL-6) in bronchoalveolar lavage fluid, and notably attenuated pulmonary fibrosis as evidenced by hydroxyproline content in silica-administered mice. These results indicated that miR-29c inhibited the development of silica-induced lung fibrosis. Thus, miR-29c may be a candidate target for silicosis treatment via its regulation of the Wnt/β-catenin pathway.

Abstract
Large multicenter clinical trials have led to two recently approved drugs for patients with idiopathic pulmonary fibrosis (IPF); yet, both of these therapies only slow disease progression and do not provide a definitive cure. Traditionally, preclinical trials have utilized mouse models of bleomycin (BLM)-induced pulmonary fibrosis—though several limitations prevent direct translation to human IPF. Spontaneous pulmonary fibrosis occurs in other animal species, including dogs, horses, donkeys, and cats. While the fibrotic lungs of these animals share many characteristics with lungs of patients with IPF, current veterinary classifications of fibrotic lung disease are not entirely equivalent. Additional studies that profile these examples of spontaneous fibroses in animals for similarities to human IPF should prove useful for both human and animal investigators. In the meantime, studies of BLM-induced fibrosis in aged male mice remain the most clinically relevant model for preclinical study for human IPF. Addressing issues such as time course of treatment, animal size and characteristics, clinically irrelevant treatment endpoints, and reproducibility of therapeutic outcomes will improve the current status of preclinical studies. Elucidating the mechanisms responsible for the development of fibrosis and disrepair associated with aging through a collaborative approach between researchers will promote the development of models that more accurately represent the realm of interstitial lung diseases in humans.

Abstract
Matrix metalloproteinases (MMPs) have been considered to contribute to the progression of tumorigenesis and tumor invasion; MMP-9 in particular, has been regarded as a priority target in cancer treatment due to its massive up-regulation in malignant tissues and its ability to degrade type IV collagen. In this work, we employed a DNA-directed covalent conjugation method to design a fluorescence probe for in vitro detection of functional matrix metalloproteinases, by which a nitrilotriacetic acid (NTA)-modified DNA probe can combine with the Zn2+ in the active site of MMPs, and then a molecule beacon (MB) modified FITC and BHQ1 can open to bond with their complementary base, NTA-modified DNA. We can evaluate the amount of MMPs in the medium according to the fluorescence intensity. The detection procedure can be finished in 30 min with good selectivity, cheap reagents and easy preparation. All the results and the amount of secreted MMPs under three different cell culture conditions are in accordance with previous reports. Satisfactory results are obtained. Furthermore, owing to the importance of MMP-9, we designed an approach to achieve the desired selectivity and specificity of our work, using dual amplification for improving fluorescence intensity based on RCA to detect the amount of MMP-9.

Abstract
Fibrotic diseases occur in virtually every tissue of the body and are a major cause of mortality, yet they remain largely untreatable and poorly understood on a mechanistic level. The development of anti-fibrotic agents has been hampered, in part, by the insufficient fibrosis biomimicry provided by traditional in vitro platforms. This review focuses on recent advancements toward creating 3-D platforms that mimic key features of fibrosis, as well as the application of novel imaging and sensor techniques to analyze dynamic extracellular matrix remodeling. Several opportunities are highlighted to apply new tools from the fields of biomaterials, imaging, and systems biology to yield pathophysiologically relevant in vitro platforms that improve our understanding of fibrosis and may enable identification of potential treatment targets.

Abstract
Pulmonary fibrosis (PF) is characterized by excessive accumulation of extracellular matrix components in the alveolar region which distorts the normal lung architecture and impairs the respiratory function. The aim of this study is to evaluate the anti-fibrotic effect of celastrol, a quinine-methide tri-terpenoid mainly found in Thunder God Vine root extracts against bleomycin (BLM)-induced PF through the enhancement of antioxidant defense system. A single intratracheal instillation of BLM (3 U/kg.bw) was administered in rats to induce PF. Celastrol (5 mg/kg) was given intraperitoneally, twice a week for a period of 28 days. BLM-induced rats exhibits declined activities of enzymatic and non-enzymatic antioxidants which were restored upon treatment with celastrol. BLM-induced rats show increased total and differential cell counts as compared to control and celastrol treated rats. Histopathological analysis shows increased inflammation and alveolar damage; while assay of hydroxyproline and Masson's trichrome staining shows an increased collagen deposition in BLM-challenged rats that were decreased upon celastrol treatment. Celastrol also reduces inflammation in BLM-induced rats as evidenced by decrease in the expressions of mast cells, Tumor necrosis factor-alpha (TNF- α) and matrix metalloproteinases (MMPs) 2 and 9. Further, Western blot analysis shows that celastrol is a potent inducer of NF-E2-related factor 2 (Nrf2) and it restores the activities of Phase II enzymes such as hemoxygenase-1 (HO-1), glutathione-S-transferase (GSTs) and NADP(H): quinine oxidoreductase (NQO1) which were declined upon BLM administration. The results of this study show evidence on the protective effect of celastrol against BLM-induced PF through its antioxidant and anti-fibrotic effects.

Abstract
The observation that pulmonary inflammatory lesions and bleomycin (BLM)-induced pulmonary fibrosis spontaneously resolve in young mice, whereas remaining irreversible in aged mice suggests that impairment of pulmonary regeneration and repair is associated with aging. Because mesenchymal stem cells (MSCs) may promote repair after injury, we postulated that differences in MSCs from aged mice may underlie postinjury fibrosis in aging. The potential for young-donor MSCs to inhibit BLM-induced pulmonary fibrosis in aged male mice (>22 months) has not been studied. Adipose-derived MSCs (ASCs) from young (4 months) and old (22 months) male mice were infused 1 day after intratracheal BLM administration. At 21-day sacrifice, aged BLM mice demonstrated lung fibrosis by Ashcroft score, collagen content, and α(v)-integrin messenger RNA (mRNA) expression. Lung tissue from aged BLM mice receiving young ASCs exhibited decreased fibrosis, matrix metalloproteinase (MMP)-2 activity, oxidative stress, and markers of apoptosis vs BLM controls. Lung mRNA expression of tumor necrosis factor-alpha was also decreased in aged BLM mice receiving young-donor ASCs vs BLM controls. In contrast, old-donor ASC treatment in aged BLM mice did not reduce fibrosis and related markers. On examination of the cells, young-donor ASCs had decreased mRNA expression of MMP-2, insulin-like growth factor (IGF) receptor, and protein kinase B (AKT) activation compared with old-donor ASCs. These results show that the BLM-induced pulmonary fibrosis in aged mice could be blocked by young-donor ASCs and that the mechanisms involve changes in collagen turnover and markers of inflammation.

Abstract
The storage and catabolism of Ultrasmall SuperParamagnetic Iron Oxide (USPIO) nanoparticles were analyzed through a multiscale approach combining Two Photon Laser Scanning Microscopy (TPLSM) and High-Resolution Transmission Electron Microscopy (HRTEM) at different times after intravenous injection in an atherosclerotic ApoE(-/-) mouse model. The atherosclerotic plaque features and the USPIO heterogeneous biodistribution were revealed down from organ's scale to subcellular level. The biotransformation of the nanoparticle iron oxide (maghemite) core into ferritin, the non-toxic form of iron storage, was demonstrated for the first time ex vivo in atherosclerotic plaques as well as in spleen, the iron storage organ. These results rely on an innovative spatial and structural investigation of USPIO's catabolism in cellular phagolysosomes. This study showed that these nanoparticles were stored as non-toxic iron compounds: maghemite oxide or ferritin, which is promising for MRI detection of atherosclerotic plaques in clinics using these USPIOs. From the Clinical Editor: Advance in nanotechnology has brought new contrast agents for clinical imaging. In this article, the authors investigated the use and biotransformation of Ultrasmall Super-paramagnetic Iron Oxide (USPIO) nanoparticles for analysis of atherosclerotic plagues in Two Photon Laser Scanning Microscopy (TPLSM) and High-Resolution Transmission Electron Microscopy (HRTEM). The biophysical data generated from this study could enable the possible use of these nanoparticles for the benefits of clinical patients.

Abstract
Pulmonary fibrosis (PF) is characterized by an increase in the number of fibroblasts and an accumulation of collagen fibers in the extracellular matrix (ECM). The members of the copper-dependent lysyl oxidase (LOX) enzyme family regulate the collagen accumulation in the ECM. Tetrathiomolybdate (TM) is a copper chelator. The present study reported the effect of TM on the expression of LOX proteins (LOX, LOXL1, and LOXL2), collagen digestion enzymes (MMP2 and MMP8), and TIMP1 (a collagenase inhibitor) in PF. The PF in mice was induced by intratracheal bleomycin instillation. Adult mice were divided into four groups: mice dissected after 21 days of the first bleomycin (0.08 mg/kg, single dose) treatment (I) and their controls (II), and mice treated with TM for 1 week (1.2 mg/day/mice for the first 4 days and 0.9 mg/day/mice for the last 3 days) after 14 days of the first bleomycin instillation and dissected in the 21st day of the experiment (III) and their controls (IV). Mice in groups III and IV were fed a low-copper (2 mg/kg) diet during the last 7 days of the experiment. The fibrosis score in the lung was determined under a microscope. The expressions of collagen-I, LOX, MMP, and TIMP1 proteins were analyzed by Western blotting in the lung. Mice lungs with fibrosis were characterized by an overexpression of collagen-I, LOX, MMP, and TIMP1 proteins in addition to an accumulation of collagen fibers. TM treatments significantly regressed the overexpression of these proteins in the fibrotic mice lung. In conclusion, TM treatments can be used for the regression of PF, by decreasing collagen-I protein expression and accumulation.

Abstract
![]()
Matrix metalloproteases (MMPs) have
been found to be highly expressed
in a variety of malignant tumor tissues. Noninvasive visualization
of MMP activity may play an important role in the diagnosis of MMP
associated diseases. Here we report the design and synthesis of a
set of fluorine-19 dendron-based magnetic resonance imaging (MRI)
probes for real-time imaging of MMP-2 activity. The probes have the
following features: (a) symmetrical fluorine atoms; (b) the number
of fluorine atoms can be increased through facile chemical modification;
(c) readily accessible peptide sequence as the MMP-2 substrate; (d)
activatable 19F signal (off/on mode) via paramagnetic metal
ion incorporation. Following optimization for water solubility, one
of the probes was selected to evaluate MMP-2 activity by 19F magnetic resonance spectroscopy (MRS). Our results showed that
the fluorine signal increased by 8.5-fold in the presence of MMP-2.
The specific cleavage site was verified by mass spectrometry. The
selected probe was further applied to detect secreted MMP-2 activity
of living SCC7 squamous cell carcinoma cells. The fluorine signal
was increased by 4.8-fold by MRS analysis after 24 h incubation with
SCC7 cells. This type of fluorine probe can be applied to evaluate
other enzyme activities by simply tuning the substrate structures.
This symmetrical fluorine dendron-based probe design extends the scope
of the existing 19F MRI agents and provides a simple but
robust method for real-time 19F MRI application.

Abstract
Active matrix metalloproteinase-3 (MMP-3) is a prognostic marker of rheumatoid arthritis (RA). We recently developed an MMP-3 probe that can specifically detect the active form of MMP-3. The aim of this study was to investigate whether detection and monitoring of active MMP-3 could be useful to predict therapeutic drug responses in a collagen-induced arthritis (CIA) model. During the period of treatment with drugs such as methotrexate (MTX) or infliximab (IFX), MMP-3 mRNA and protein levels were correlated with fluorescence signals in arthritic joint tissues and in the serum of CIA mice. Also, bone volume density and erosion in the knee joints and the paws of CIA mice were measured with microcomputed tomography (micro-CT), X-ray, and histology to confirm drug responses. In joint tissues and serum of CIA mice, strong fluorescence signals induced by the action of active MMP-3 were significantly decreased when drugs were applied. The decrease in RA scores in drug-treated CIA mice led to fluorescence reductions, mainly as a result of down-regulation of MMP-3 mRNA or protein. The micro-CT, X-ray, and histology results clearly showed marked decreases in bone and cartilage destruction, which were consistent with the reduction of fluorescence by down-regulation of active MMP-3 in drug-treated CIA mice. We suggest that the MMP-3 diagnostic kit could be used to detect and monitor the active form of MMP-3 in CIA mice serum during a treatment course and thereby used to predict the drug response or resistance to RA therapies at an earlier stage. We hope that monitoring of active MMP-3 levels in arthritis patients using the MMP-3 diagnostic kit will be a promising tool for drug discovery, drug development, and monitoring of drug responses in RA therapy.

Abstract
Because of the important roles that matrix metalloproteinases (MMPs) play in tumor invasion and metastasis, various activatable optical probes have been developed to visualize MMP activities in vitro and in vivo. Our recently developed MMP-13 activatable probe, l-MMP-P12, has been successfully applied to image the expression and inhibition of MMPs in a xenografted tumor model [Zhu, L., et al. (2011) Theranostics 1, 18-27]. In this study, to further optimize the in vivo behavior of the proteinase activatable probe, we tracked and profiled the metabolites by a high-resolution liquid chromatography-mass spectrometry (LC-MS) system. Two major metabolites that contributed to the fluorescence recovery were identified. One was specifically cleaved between glycine (G(4)) and valine (V(5)) by MMP, while the other one was generated by nonspecific cleavage between glycine (G(7)) and lysine (K(8)). To visualize the MMP activity more accurately and specifically, a new probe, D-MMP-P12, was designed by replacing the l-lysine with d-lysine in the MMP substrate sequence. The metabolic profile of the new probe, D-MMP-P12, was further characterized by in vitro enzymatic assay, and no nonspecific metabolite was found by LC-MS. Our in vivo optical imaging also demonstrated that D-MMP-P12 had a tumor-to-background ratio (TBR, 5.55 ± 0.75) significantly higher than that of L-MMP-P12 (3.73 ± 0.31) 2 h postinjection. The improved MMP activatable probe may have the potential for drug screening, tumor diagnosis, and therapy response monitoring. Moreover, our research strategy can be further extended to study other protease activatable probes.

Abstract
Biobanks have played a decisive role in all aspects of the field of cancer, including pathogenesis, diagnosis, prognosis and treatment. The significance of cancer biobanks is epitomized through the appropriate application of various "-omic" techniques (omics). The mutually motivated relationship between biobanks and omics has intensified the development of cancer research. Human cancer tissues that are maintained in intravital biobanks (or living tissue banks) retain native tumor microenvironment, tissue architecture, hormone responsiveness and cell-to-cell signalling properties. Intravital biobanks replicate the structural complexity and heterogeneity of human cancers, making them an ideal platform for preclinical studies. The application of omics with intravital biobanks renders them more active, which makes it possible for the cancer-related evaluations to be dynamically monitored on a real-time basis. Integrating intravital biobank and modern omics will provide a useful tool for the discovery and development of new drugs or novel therapeutic strategies. More importantly, intravital biobanks may play an essential role in the creation of meaningful patient-tailored therapies as for personalized medicine.
