Trastuzumab-Pertuzumab Plus Eribulin or Taxane as First-Line Chemotherapy for Human Epidermal Growth Factor 2-Positive Locally Advanced/Metastatic Breast Cancer: The Randomized Noninferiority Phase III EMERALD Trial.

Purpose: Trastuzumab-pertuzumab (HP) plus taxane is a current standard first-line therapy for recurrent or metastatic human epidermal growth factor 2 (HER2)+ breast cancer (BC). We investigated noninferiority of eribulin to a taxane when combined with dual HER2 blockade as first-line systemic treatment for locally advanced/metastatic HER2+ BC.

Methods: In the phase III EMERALD trial (target sample size, 480; ClinicalTrials.

Cationic-nanogel nasal vaccine containing the ectodomain of RSV-small hydrophobic protein induces protective immunity in rodents.

Respiratory syncytial virus (RSV) is a leading cause of upper and lower respiratory tract infection, especially in children and the elderly. Various vaccines containing the major transmembrane surface proteins of RSV (proteins F and G) have been tested; however, they have either afforded inadequate protection or are associated with the risk of vaccine-enhanced disease (VED). Recently, F protein-based maternal immunization and vaccines for elderly patients have shown promising results in phase III clinical trials, however, these vaccines have been administered by injection.

Lactobacilli as a Vector for Delivery of Nanobodies against Norovirus Infection.

Passive administration of neutralizing antibodies (Abs) is an attractive strategy for the control of gastrointestinal infections. However, an unanswered practical concern is the need to assure the stability of sufficient amounts of orally administered neutralizing Abs against intestinal pathogens (e.g.

Oral MucoRice-CTB vaccine for safety and microbiota-dependent immunogenicity in humans: a phase 1 randomised trial.

Background: There are an estimated 1·3-4·0 million cases of cholera and 20 000-140 000 cholera-related deaths worldwide each year. The rice-based cholera toxin B subunit (CTB) vaccine, MucoRice-CTB, is an oral candidate vaccine that does not require a cold chain, has shown efficacy in animal models, and could be of benefit in places where there is a paucity of medical infrastructure. We aim to assess the safety, tolerability, and immunogenicity of MucoRice-CTB in humans.

A nanogel-based trivalent PspA nasal vaccine protects macaques from intratracheal challenge with pneumococci.

Current polysaccharide-based pneumococcal vaccines are effective but not compatible with all serotypes of Streptococcus pneumoniae. We previously developed an adjuvant-free cationic nanogel nasal vaccine containing pneumococcal surface protein A (PspA), which is expressed on the surfaces of all pneumococcal serotypes. Here, to address the sequence diversity of PspA proteins, we formulated a cationic nanogel-based trivalent pneumococcal nasal vaccine and demonstrated the vaccine's immunogenicity and protective efficacy in macaques by using a newly developed nasal spray device applicable to humans.

A role for the CCR5-CCL5 interaction in the preferential migration of HSV-2-specific effector cells to the vaginal mucosa upon nasal immunization.

Our current study focused on elucidating the role of specific chemokine-receptor interactions in antigen (Ag)-specific immune cell migration from nasal to genital mucosal tissues. This cellular migration is critical to induce effective Ag-specific immune responses against sexually transmitted genital infections. In this study, nasal immunization with live attenuated HSV-2 TK induced the upregulation of CCR5 expression in effector immune cells, including CD4 T cells, in Ag-priming sites and vaginal tissue.

The stress response gene ATF3 is a direct target of the Wnt/β-catenin pathway and inhibits the invasion and migration of HCT116 human colorectal cancer cells.

Aberrant Wnt/β-catenin signaling is implicated in tumorigenesis and the progression of human colorectal cancers, and mutations in the components of the Wnt/β-catenin signaling pathway are observed in the majority of patients. Therefore, extensive studies on the Wnt signaling pathway and its target genes are crucial to understand the molecular events of tumorigenesis and develop an efficacious therapy. In this study, we showed that the stress response gene ATF3 is transcriptionally activated by the binding of β-catenin and TCF4 to the redundant TCF4 site at the proximal promoter region of the ATF3 gene, indicating that ATF3 is a direct target of the Wnt/β-catenin pathway.

Transcriptional properties of mammalian elongin A and its role in stress response.

Elongin A was shown previously to be capable of potently activating the rate of RNA polymerase II (RNAPII) transcription elongation in vitro by suppressing transient pausing by the enzyme at many sites along DNA templates. The role of Elongin A in RNAPII transcription in mammalian cells, however, has not been clearly established. In this report, we investigate the function of Elongin A in RNAPII transcription.
