In this study, we report a gas-forming drug carrier engineered using the liposomal magnetoporation method. The liposomes that were magnetoporated under a magnetic shear stress possessed an opened lipid bilayer hole. A photosensitizing model drug (chlorin e6: Ce6) and 1H-1H-2H-perfluoro-1-hexene (PFH, as a volatile gas-forming agent) were efficiently loaded into the opened holes of the magnetoporated liposomes. PFH in the liposomes is vaporized at 50°C and can initiate liposome destabilization. The experimental results demonstrated that the liposomes were destabilized at 50°C efficiently released Ce6 and enhanced Ce6-mediated phototoxicity against KB tumor cells...

During a certain critical period in the development of the central and peripheral nervous systems, axonal branches and synapses are massively reorganized to form mature connections. In this process, neurons search their appropriate targets, expanding and/or retracting their axons. Recent work suggested that the caspase superfamily regulates the axon morphology. Here, we tested the hypothesis that caspase 3, which is one of the major executioners in apoptotic cell death, is involved in regulating the axon arborization...

BACKGROUND: We have been developing a non-thermal, drug-free tumor therapy called Nano-Pulse Stimulation (NPS) that delivers ultrashort electric pulses to tumor cells which eliminates the tumor and inhibits secondary tumor growth. We hypothesized that the mechanism for inhibiting secondary tumor growth involves stimulating an adaptive immune response via an immunogenic form of apoptosis, commonly known as immunogenic cell death (ICD). ICD is characterized by the emission of danger-associated molecular patterns (DAMPs) that serve to recruit immune cells to the site of the tumor...

HPV204 is the only newly identified Mupapillomavirus (Mu-PV) type in more than a decade. To comprehensively characterize HPV204, we performed a detailed molecular analysis of the viral genome and evaluated its clinical relevance in comparison to the other Mu-PVs, HPV1 and HPV63. The 7,227-bp long genome of HPV204 exhibits typical genomic organization of Mu-PVs with eight open reading frames (ORFs) (E6, E7, E1, E2, E8, E4, L2, and L1). We developed three type-specific quantitative real-time PCRs and used them to test a representative collection (n = 1,006) of various HPV-associated benign and malignant neoplasms, as well as samples of clinically normal cutaneous, mucosal, and mucocutaneous origins...

We analyzed uncertainties and complexities of the Zika virus outbreak in Brazil, and we discuss risk reduction for future emergencies. We present the public health situation in Brazil and concurrent determinants of the epidemic and the knowledge gaps that persist despite building evidence from research, making public health decisions difficult. Brazil has adopted active measures, but producing desired outcomes may be uncertain because of partial or unavailable information. Reducing population group vulnerabilities and acting on environmental issues are medium- to long-term measures...

Physician-assisted death is now legal in California, and similar laws are being considered in many other states. The California law includes safeguards, yet health care providers will face practical and ethical issues while implementing physician-assisted death that are not addressed by the law. To help providers and health care facilities in California prepare to provide optimal care to patients who inquire about physician-assisted death, we brought together experts from California, Oregon, and Washington...

Human papillomavirus type 16 (HPV16) is the major cause of cervical cancer and of a fraction of oropharyngeal carcinoma. Few studies compared the viral expression profiles in the two types of tumor. We analyzed HPV genotypes and viral load as well as early (E2/E4, E5, E6, E6*I, E6*II, E7) and late (L1 and L2) gene expression of HPV16 in cervical and oropharyngeal cancer biopsies. The study included 28 cervical squamous cell carcinoma (SCC) and ten oropharyngeal SCC, along with pair-matched non-tumor tissues, as well as four oropharynx dysplastic tissues and 112 cervical intraepithelial neoplasia biopsies...

Human papillomavirus (HPV) infections predict mortality in Taiwanese patients with oral cavity squamous cell carcinoma (OCSCC). To address their prognostic significance for local recurrence (LR), in this retrospective cohort study we investigated different serologic and molecular markers of HPV 16 infection in 85 consecutive patients with primary OCSCC who received standard treatment and had their sera stored before treatment. Resected tumor specimens were examined with PCR-based assays for HPV 16 E6/E7 mRNA expression...

One important goal of cancer immunotherapy is to prevent and treat tumor metastasis. We have previously reported the significant antitumor effect induced by the immunization with our human papillomavirus therapeutic protein-based vaccine (LALF32-51-E7) without adjuvant and admixed with clinically relevant adjuvants in the subcutaneous TC-1 tumor challenge model. In the present study, we evaluated the efficacy of the above mentioned vaccine formulations in controlling the hematogenous spread of TC-1 tumor cells using a more tumourigenic clone named TC-1* and other intravenous injection site less stressful than the tail vein...

Curcumin (from curry) (C) is highly potent against cervical cancer cells (CCC), but poor bioavailability has limited its clinical use. Similar natural polyphenols resveratrol (from grapes) (R), and epicatechin gallate (from green tea) (E) also display activity against CCC. By treating CCC (HeLa) with C, E, or R, or combinations of these compounds, we computed combination indices and observed a strong synergism among C, E, and R at the unique molar ratio 4:1:12.5. This combination, named as TriCurin, rapidly down regulated HPV18 E6 and NF-kB expression while concomitantly inducing the tumor suppressor protein p53 in HeLa cells...

Chlorin-based photosensitizers are commonly used in photodynamic therapy (PDT).  These drugs are effluxed by cell-membrane transporters, such as the ATP-binding cassette subfamily G member 2 (ABCG2). PDT efficacy is limited in tumor cells expressing high levels of these proteins. Pancreatic cancer cell lines AsPC-1 and MIA PaCa-2, which have high and low ABCG2 expression, respectively, were used and ABCG2-overexpressing MIA PaCa-2 cells were generated. We compared PDT efficacy between Chlorin e6 (Ce6) and cationic photosensitizer-encapsulated polymeric nanoparticle (PS-pNP) which is comprised with Ce6, polyethylene glycol and polyethylenimine...

High-risk human papillomavirus (HPV) infection is the etiological agent of some malignancies such as cervical, oral and oropharyngeal cancers. Kaposi sarcoma-associated herpesvirus (KSHV) represents a principal causative agent of several human cancers arising in those immunocompromised patients. Interestingly, KSHV DNA has been detected in the oral cavity and the female genital tract, although its detection rate in cervical samples is very low and few reports are about KSHV/HPV co-infection. Therefore, it remains unclear about the role of KSHV co-infection in the development of HPV-related neoplasias...

In asymmetric chick gonads, the left and right female gonads undergo distinct programs during development, generating a functional ovary on the left side only. Despite some progress being made in recent years, the mechanisms of molecular regulation remain incompletely understood, and little genomic information is available regarding the degeneration of the right ovary in the chick embryo testis. In this study, we performed transcriptome sequencing to investigate differentially expressed genes in the left and right ovaries and gene functions at two critical time points; embryonic days 6 (E6) and 10 (E10)...

BACKGROUND: Due to their ability to limitlessly proliferate and specialize into almost any cell type, human induced pluripotent stem cells (iPSCs) offer an unprecedented opportunity to generate human brain microvascular endothelial cells (BMECs), which compose the blood-brain barrier (BBB), for research purposes. Unfortunately, the time, expense, and expertise required to differentiate iPSCs to purified BMECs precludes their widespread use. Here, we report the use of a defined medium that accelerates the differentiation of iPSCs to BMECs while achieving comparable performance to BMECs produced by established methods...

Phosphatidylinositol-3-phosphate 5-kinase (PIKfyve) is a lipid kinase involved in endosome maturation that emerged from a haploid genetic screen as being required for Ebola virus (EBOV) infection. Here we analyzed the effects of apilimod, a PIKfyve inhibitor that was reported to be well tolerated in humans in phase 2 clinical trials, for its effects on entry and infection of EBOV and Marburg virus (MARV). We first found that apilimod blocks infections by EBOV and MARV in Huh 7, Vero E6 and primary human macrophage cells, with notable potency in the macrophages (IC50, 10 nM)...
