Abstract
Neurodegenerative diseases and cancers are considered to be two families of diseases caused by completely opposite cell-death mechanisms: the former caused by premature cell death, with the latter due to the increased resistance to cell death. Growing epidemiologic evidence appear to suggest an inverse correlation between neurodegenerative diseases and cancers. However, pathological links, particularly from a protein-cell interaction perspective, between these two families of diseases remains to be proven. Here, a fundamental study investigates the effects of three amyloid proteins of Aβ (associated with AD), hIAPP (associated with T2D), and hCT (associated with MTC) on pancreatic cancer (PANC-1) cells. Collective results demonstrate a general inhibitory activity of all of three amyloid proteins on cancer cell proliferation, but inhibition efficiencies are strongly dependent on amyloid sequence (Aβ, hIAPP, hCT), concentration (IC25, IC50, IC75), and aggregation states (monomers, oligomers). Amyloid proteins exhibit two pathways against cancer cells: amyloid monomer-induced ROS production to inhibit cell growth and amyloid oligomer-induced membrane disruption to kill cells. Collectively, the results demonstrate a general inhibition function of amyloid proteins to induce cancer cell death by preventing cell proliferation, suppressing cell migration, promoting reactive oxygen species production, and disrupting cell membranes.

Abstract
The misfolding of amyloid beta (Aβ) peptides into Aβ fibrillary aggregates is a major hallmark of Alzheimer's disease (AD), which responsible for the excess production of hydrogen peroxide (H2O2), a prominent reactive oxygen species (ROS) from the molecular oxygen (O2) by the reduction of the Aβ-Cu(I) complex. The excessive production of H2O2 causes oxidative stress and inflammation in the AD brain. Here, we have designed and developed a dual functionalized molecule VBD by using π-conjugation (C═C) in the backbone structure. In the presence of H2O2, the VBD can turn into fluorescent probe VBD-1 by cleaving of the selective boronate ester group. The fluorescent probe VBD-1 can undergo intramolecular charge transfer transition (ICT) by a π-conjugative system, and as a result, its emission increases from the yellow (532 nm) to red (590 nm) region. The fluorescence intensity of VBD-1 increases by 3.5-fold upon binding with Aβ fibrillary aggregates with a high affinity (Kd = 143 ± 12 nM). Finally, the VBD reduces the cellular toxic H2O2 as proven by the CCA assay and DCFDA assay and the binding affinity of VBD-1 was confirmed by using in vitro histological staining in 8- and 18-month-old triple transgenic AD (3xTg-AD) mice brain slices.

Abstract
Cancer stem cells (CSCs) play crucial roles in tumor initiation. Amyloid β (Aβ), which is associated with Alzheimer's disease (AD), has been identified to induce cytotoxicity in tumor cells besides brain cells. Herein, we find that oligomeric Aβ1-42 and Aβ1-40 (OAβ1-42 and OAβ1-40) can repress the viability of breast CSCs. Intriguingly, OAβ1-42 and OAβ1-40 preferentially induce the growth arrest of breast CSCs by contrast with the bulk cancer cells. Further studies indicate that OAβ1-42 and OAβ1-40 disturb iron homeostasis, which results in iron accumulation in lysosomes. The iron in lysosomes then induces ROS production by Fenton reaction, leading to breast CSC death. In vivo experiments show that the tumorigenesis of breast CSCs pretreated with OAβ1-42 is inhibited. These results reveal that OAβ1-42 and OAβ1-40 are multifaceted players with the ability to eliminate CSCs. Our work may provide a new clue to better understand the biological functions of amyloid oligomers.

Abstract
Microtubule is one of the most studied targets in cancer research. Stabilizing and destabilizing of the microtubule by targeting its building block tubulin are common mechanisms of microtubule targeting agents. Cancer associates inversely with Alzheimer's disease (AD). So the rate of developing AD is significantly slower in patients with cancer and vice versa. Amyloid-β (Aβ) peptide inhibits tubulin polymerization and induces apoptotic death of cancer cells. We studied the interactions of Aβ with tubulin using protein-protein docking and MD simulation. Aβ bond to the vicinity of the vinblastine binding site and interacted with the H6-H7 loop. Interaction of Aβ with H6-H7 loop blocked nucleotide exchange and may be attributed as a possible reason for blocking of tubulin polymerization. We designed new Aβ-based peptidic inhibitors of tubulin using visual inspection and alanine scanning method. P1 (FRHYHHFFELV) and P9 (HYHHF) bound efficiently to tubulin and also interacted with the H6-H7 loop. Obtained results indicated that proposed peptides could potentially inhibit nucleotide exchange as Aβ.Communicated by Ramaswamy H. Sarma.

Abstract
Ceramide-rich platforms (CRPs) mediate association of proteins with the sphingolipid ceramide and may regulate protein interaction in membrane contact sites to the cytoskeleton, organelles, and infectious pathogens. However, visualization of ceramide association to proteins is one of the greatest challenges in understanding the cell biology of ceramide. Here we introduce a novel labeling technique for ceramide-associated proteins (CAPs) by combining photoactivated cross-linking of a bioorthogonal and bifunctional ceramide analog, pacFACer with proximity ligation assays (PLAs). pacFACer cross-linked to CAPs is covalently attached to a fluorophore using click chemistry. PLAs use antibodies to: (1) the candidate CAP and the fluorophore (PLA1); and (2) the CAP and ceramide (PLA2). PLA1 shows the subcellular localization of a particular CAP that is cross-linked to pacFACer, while PLA2 tests if the cross-linked CAP forms a complex with endogenous ceramide. Two proteins, tubulin and voltage-dependent anion channel 1 (VDAC1), were cross-linked to pacFACer and showed PLA signals for a complex with ceramide and pacFACer, which were predominantly colocalized with microtubules and mitochondria, respectively. Binding of tubulin and VDAC1 to ceramide was confirmed by coimmunoprecipitation assays using anti ceramide antibody. Cross-linking to pacFACer was confirmed using click chemistry-mediated attachment of biotin and streptavidin pull-down assays. Inhibition of ceramide synthases with fumonisin B1 (FB1) reduced the degree of pacFACer cross-linking and complex formation with ceramide, while it was enhanced by amyloid beta peptide (Aβ). Our results show that endogenous ceramide is critical for mediating cross-linking of CAPs to pacFACer and that a combination of cross-linking with PLAs (cross-link/PLA) is a novel tool to visualize CAPs and to understand the regulation of protein interaction with ceramide in CRPs.

Abstract
Amyloid-beta (Aβ) peptide misfolds into fibrillary aggregates (β-sheet) and is deposited as amyloid plaques in the cellular environment, which severely damages intraneuronal connections leading to Alzheimer's disease (AD) pathogenesis. Furthermore, neurons are rich in tubulin/microtubules, and the intracellular network of microtubules also gets disrupted by the accumulation of Aβ fiber in the brain. Hence, development of new potent molecules, which can simultaneously inhibit Aβ fibrillations and stabilize microtubules, is particularly needed for the efficient therapeutic application in AD. To address these issues, here we introduced an innovative fusion strategy to design and develop next generation anti-AD therapeutic leads. This unexplored fusion strategy entails design and development of a potent nonapeptide by taking into account both the hydrophobic core (17-21) of Aβ peptide and the taxol binding region of β-tubulin. In vitro results suggest that this newly designed peptide interacts at the taxol binding region of β-tubulin with a moderate binding affinity and promotes microtubule polymerization. It has the ability to bind at the hydrophobic core (17-21) of Aβ, responsible for its aggregation, and prevent amyloid fibril as well as plaque formation. In addition, it interacts at the CAS site (catalytic anionic site) of acetylcholinesterase (AChE) and significantly inhibits AChE induced Aβ fibrillation, stimulates neurite branching, and provides stability to intracellular microtubules and extensive protection of neurons against nerve growth factor (NGF) deprived neuron toxicity. Moreover, this newly designed peptide shows good stability in serum obtained from humans and efficiently permeates the blood-brain barrier (BBB) without showing any toxicity toward differentiated PC12 neurons as well as primary rat cortical neurons. This excellent feature of protecting the neurons by stabilizing the microtubules without showing any toxicity toward neurons will make this peptide a potent therapeutic agent of AD in the near future.

Abstract
Aβ peptide and hyper-phosphorylated microtubule associated protein (Tau) aggregation causes severe damage to both the neuron membrane and key signal processing microfilament (microtubule) in Alzheimer's disease (AD) brains. To date, the key challenge is to develop nontoxic, proteolytically stable amyloid inhibitors, which can simultaneously target multiple pathways involved in AD. Various attempts have been made in this direction; however, clinical outcomes of those attempts have been reported to be poor. Thus, we choose development of peptoid (N-substituted glycine oligomers)-based leads as potential AD therapeutics, which are easy to synthesize, found to be proteolytically stable, and exhibit excellent bioavailability. In this paper, we have designed and synthesized a new short peptoid for amyloid inhibition from 30-34 hydrophobic pocket of amyloid beta (Aβ) peptide. The peptoid selectively binds with 17-21 hydrophobic region of Aβ and inhibits Aβ fibril formation. Various in vitro assays suggested that our AI peptoid binds with tubulin/microtubule and promotes its polymerization and stability. This peptoid also inhibits AChE-induced Aβ fibril formation and provides significant neuroprotection against toxicity generated by nerve growth factor (NGF) deprived neurons derived from rat adrenal pheochromocytoma (PC12) cell line. Moreover, this peptoid shows serum stability and is noncytotoxic to primary rat cortical neurons.

Abstract
Microtubules play a crucial role in maintaining the shape and function of neurons. During progression of Alzheimer's disease (AD), severe destabilization of microtubules occurs, which leads to the permanent disruption of signal transduction processes and memory loss. Thus, microtubule stabilization is one of the key requirements for the treatment of AD. Taxol, a microtubule stabilizing anticancer drug, has been considered as a potential anti-AD drug but was never tested in AD patients, likely because of its' toxic nature and poor brain exposure. However, other microtubule-targeting agents such as epothilone D (BMS-241027) and TPI-287 (abeotaxane) and NAP peptide (davunetide) have entered in AD clinical programs. Therefore, the taxol binding pocket of tubulin could be a potential site for designing of mild and noncytotoxic microtubule stabilizing molecules. Here, we adopted an innovative strategy for the development of a peptide based microtubule stabilizer, considering the taxol binding pocket of β-tubulin, by using alanine scanning mutagenesis technique. This approach lead us to a potential octapeptide, which strongly binds to the taxol pocket of β-tubulin, serves as an excellent microtubule stabilizer, increases the expression of acetylated tubulin, and acts as an Aβ aggregation inhibitor and neuroprotective agent. Further, results revealed that this peptide is nontoxic against both PC12 derived neurons and primary cortical neurons. We believe that our strategy and discovery of peptide-based microtubule stabilizer will open the door for the development of potential anti-AD therapeutics in near future.

Abstract
Microtubules regulate eukaryotic cell functions, which have tremendous implication in tumor progression. Thus, the design of novel approaches for controlling microtubule function is extremely important. In this manuscript, a novel tetrapeptide Ser-Leu-Arg-Pro (SLRP) has been designed and synthesized from a small peptide library consisting of 14 tetrapeptides, which perturbs microtubule function through interaction in the "anchor region". We have studied the role of peptides on microtubule function on a chemically functionalized 2D platform. Interestingly, we have found that SLRP binds with tubulin and inhibits the kinesin-driven microtubule motility on a kinesin-immobilized chemically functionalized 2D platform. Further, this peptide modulator interacts with intracellular tubulin/microtubule and depolymerizes the microtubule networks. These interesting findings of perturbation of microtubule function both on engineered platforms and inside the cell by this small peptide modulator inspired us to study the effect of this tetrapeptide on cancer cell proliferation. We found that the novel tetrapeptide modulator causes moderate cytotoxicity to the human breast cancer cell (MCF-7 cell), induces the apoptotic death of MCF-7 cell, and activates the tumor suppressor proteins p53 and cyclin-dependent kinase inhibitor 1 (p21). To the best of our knowledge, this is the shortest peptide discovered, which perturbs microtubule function both on an engineered 2D platform and inside the cell.

Biomed Pharmacother 2017; 89:36-46. [PMID: 28214686 DOI: 10.1016/j.biopha.2017.02.019] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2017] [Revised: 02/02/2017] [Accepted: 02/07/2017] [Indexed: 01/16/2023] Open
Abstract
Tubulin targeting agents have received considerable interest as a potential tumor-selective vascular disrupting agents, which represent another avenue for cancer growing therapeutic opportunities. Hence, the present study was conducted to investigate the anti-tumor activity of Combretastatin A-4 phosphate (CA4-P) and vincristine against hepatocellular carcinoma in rats, by individual administration and in combination. In vitro study was conducted using human hepatocellular carcinoma cell lines, showed that CA4-P and vincristine have a potent cell cytotoxic and tubulin inhibitory effect. In addition, a remarkable synergistic effect was observed by the simultaneous application of both drugs. Whereas in vivo study was conducted using model of rat liver cancer initiated with DENA and promoted by CCl4, showed that CA4-P and vincristine were significantly decreased liver relative weight, number of hepatic nodules and there relative volumes, tubulin content of the hepatic tissue, GSH and AFP. On the other hand, co-administration of both drugs exhibited significant further decrements in these parameters. Whereas a marked increase in MDA, carbonyl content and TNF-α inside hepatic tissue were observed in the treated groups and these increments were more prominent by co-administration of both drugs. In conclusion CA4-P showed a potential anti-cancer activity against hepatocellular carcinoma and this effect was greatly enhanced by co-administration with vincristine. Additionally, our new findings provided an important evidence that the anticancer activity of drugs with a narrow therapeutic window such as vincristine can be greatly improved by its co-administration with CA4-P providing more enhanced activity with less side effects.

Abstract
Microtubule dynamics play a crucial role in cancer cell division. Various drugs are developed to target microtubule. Although a few of them show potential in treatment of cancer, but success rate is limited due to their poor bioavailability and lack of specificity. Thus, development of highly bioavailable and target specific anticancer drug is extremely necessary. To address these key issues, here, a combination of approaches such as development of a dodecapeptide-docetaxel nanoassembly targeted to tubulin and MUC1 (mucin 1, cell surface associated glycoprotein) targeting oligonucleotide aptamer conjugated liposome for delivering peptide-docetaxel nanoassembly into the breast cancer cell have been demonstrated. These studies reveal that the peptide forms nanoassembly and entraps docetaxel drug. Further, the liposomal formulation of peptide-docetaxel exerts synergistic anticancer effect, activates key mitotic check point proteins, and inhibits bipolar spindle formation, metastatic cancer cell migration, and growth of tumor mimicking 3D multicellular spheroid.

Abstract
Accumulation of amyloid beta (Aβ) peptide and its aggregates in the human brain is considered as one of the hallmarks of Alzheimer's disease (AD). The polymorphic oligomers and fully grown fibrillar aggregates of Aβ exhibit different levels of neuronal toxicity. Moreover, aggregation of Aβ in the presence of redox-active metal ions like Cu(2+) is responsible for the additional trait of cellular toxicity induced by the generation of reactive oxygen species (ROS). Herein, a multifunctional peptidomimetic inhibitor (P6) has been presented, based on a naturally occurring metal chelating tripeptide (GHK) and the inhibitor of Aβ aggregation. It was shown by employing various biophysical studies that P6 interact with Aβ and prevent the formation of toxic Aβ forms like oligomeric species and fibrillar aggregates. Further, P6 successfully sequestered Cu(2+) from the Aβ-Cu(2+) complex and maintained it in a redox-dormant state to prevent the generation of ROS. P6 inhibited membrane disruption by Aβ oligomers and efficiently prevented DNA damage caused by the Aβ-Cu(2+) complex. PC12 cells were rescued from multifaceted Aβ toxicity when treated with P6, and the amount of ROS generated in cells was reduced. These attributes make P6 a potential therapeutic candidate to ameliorate the multifaceted Aβ toxicity in AD.

Abstract
Tubulin is the key cytoskeleton component, which plays a crucial role in eukaryotic cell division. Many anticancer drugs have been developed targeting the tubulin surface. Recently, it has been shown that few polyhydroxy carbohydrates perturb tubulin polymerization. Cyclodextrin (CD), a polyhydroxy carbohydrate, has been extensively used as the delivery vehicle for delivery of hydrophobic drugs to the cancer cell. However, interaction of CD with intracellular components has not been addressed before. In this Article, we have shown for the first time that α-CD interacts with tubulin close to the vinblastine site using molecular docking and Förster resonance energy transfer (FRET) experiment. In addition, we have shown that α-CD binds with intracellular tubulin/microtubule. It delivers a high amount of curcumin onto the cancer cell, which causes severe disruption of intracellular microtubules. Finally, we have shown that the inclusion complex of α-CD and curcumin (CCC) preferentially enters into the human lung cancer cell (A549) as compared to the normal lung fibroblast cell (WI38), causes apoptotic death, activates tumor suppressor protein (p53) and cyclin-dependent kinase inhibitor 1 (p21), and inhibits 3D spheroid growth of cancer cell.

Abstract
Herein, we report a novel hexapeptide, derived from activity dependent neuroprotective protein (ADNP), that spontaneously self-assembles to form antiparallel β-sheet structure and produces nanovesicles under physiological conditions. This peptide not only strongly binds with β-tubulin in the taxol binding site but also binds with the microtubule lattice in vitro as well as in intracellular microtubule networks. Interestingly, it shows inhibition of amyloid fibril formation upon co-incubation with Aβ peptide following an interesting mechanistic pathway and excellent neuroprotection in PC12 cells treated with anti-nerve growth factor (NGF). The potential of this hexapeptide opens up a new paradigm in design and development of novel therapeutics for AD.
