Anti-cancer effects of DHP107 on canine mammary gland cancer examined through in-vitro and in-vivo mouse xenograft models.

Background: Canine mammary gland cancer (CMGC) is a common neoplasm in intact bitches. However, the benefit of adjuvant chemotherapy is unclear. The aim of this study was to investigate the anti-proliferative effects of paclitaxel on CMGC in in-vitro and in-vivo settings.

Assessment of salivary alpha-amylase and cortisol as a pain related stress biomarker in dogs pre-and post-operation.

Background: The use of salivary biomarkers has garnered attention because the composition of saliva reflects the body's physiological state. Saliva contains a wide range of components, including peptides, nucleic acids, electrolytes, enzymes, and hormones. It has been reported that salivary alpha-amylase and cortisol are biomarkers of stress related biomarker in diseased dogs; however, evaluation of salivary alpha-amylase and cortisol pre- and post- operation has not been studied yet.

TLR4/MD2 specific peptides stalled in vivo LPS-induced immune exacerbation.

Negative regulation of Toll-like receptor-4 (TLR4) is anticipated to control the pathogen-induced exaggerated immune response. However, effective TLR4 antagonists with scarce off-target effects are yet to be developed. To fill this void, we sought to design small peptide-inhibitors of the TLR4/MD2-LPS interaction.

Protective effects of ginsenoside F2 on 12-O-tetradecanoylphorbol-13-acetate-induced skin inflammation in mice.

Topical use of ginsenosides, the major bioactive substances in Panax ginseng, has been used for the treatment of irritated skin complaints. However, the protective mechanisms of ginsenosides remain unclear. In the present study, we investigated the anti-inflammatory role of ginsenoside F2 (GF2) on the skin inflammation.

Elevated cortisol content in dog hair with atopic dermatitis.

Canine atopic dermatitis (CAD) is a chronic relapsing inflammatory skin disease occurring in 10% of the canine population. Although most studies have focused on the pathophysiological mechanism involved in CAD, the detrimental impact of CAD on quality of life has received only little attention. Hair cortisol analysis is becoming a valuable tool in monitoring chronic stress.

Exosome-mediated activation of toll-like receptor 3 in stellate cells stimulates interleukin-17 production by γδ T cells in liver fibrosis.

Unlabelled: During liver injury, hepatocytes secrete exosomes that include diverse types of self-RNAs. Recently, self-noncoding RNA has been recognized as an activator of Toll-like receptor 3 (TLR3). However, the roles of hepatic exosomes and TLR3 in liver fibrosis are not yet fully understood.

In silico mechanistic analysis of IRF3 inactivation and high-risk HPV E6 species-dependent drug response.

The high-risk human papillomavirus E6 (hrHPV E6) protein has been widely studied due to its implication in cervical cancer. In response to viral threat, activated kinases phosphorylate the IRF3 autoinhibitory domain, inducing type1 interferon production. HPV circumvents the antiviral response through the possible E6 interaction with IRF3 and abrogates p53's apoptotic activity by recruiting E6-associated protein.

Etoposide Induces Necrosis Through p53-Mediated Antiapoptosis in Human Kidney Proximal Tubule Cells.

The p53 protein is an important transcription factor that modulates signaling pathways for both cell death and survival. Its antiapoptotic mechanisms that correlate with necrotic and apoptotic cell death are not well understood. Here, we report that etoposide promotes progression of the DNA damage response as well as necrotic morphological changes including plasma membrane rupture using carbon nanotube-tipped/atomic force microscopy (CNT/AFM) probes in human kidney proximal tubule (HK-2) cells.

Treatment with 4-methylpyrazole modulated stellate cells and natural killer cells and ameliorated liver fibrosis in mice.

Background & Aims: Accumulating evidence suggests that retinol and its metabolites are closely associated with liver fibrogenesis. Recently, we demonstrated that genetic ablation of alcohol dehydrogenase 3 (ADH3), a retinol metabolizing gene that is expressed in hepatic stellate cells (HSCs) and natural killer (NK) cells, attenuated liver fibrosis in mice. In the current study, we investigated whether pharmacological ablation of ADH3 has therapeutic effects on experimentally induced liver fibrosis in mice.

Clinical use of a ceramide-based moisturizer for treating dogs with atopic dermatitis.

In humans, skin barrier dysfunction is thought to be responsible for enhanced penetration of allergens. Similar to conditions seen in humans, canine atopic dermatitis (CAD) is characterized by derangement of corneocytes and disorganization of intercellular lipids in the stratum corenum (SC) with decreased ceramide levels. This study was designed to evaluate the effects of a moisturizer containing ceramide on dogs with CAD.

Molecular analysis of Malassezia pachydermatis isolated from canine skin and ear in Korea.

We investigated Malassezia species and genotypes colonizing dogs, comparing those recovered from the ear canal with those from other anatomical body sites, as well as from diseased and healthy skin. The Malassezia isolates were obtained from four types of skin samples, i.e.

Evaluation of the effect of a 0.0584% hydrocortisone aceponate spray on clinical signs and skin barrier function in dogs with atopic dermatitis.

The purpose of this study was to evaluate the effects of a topical spray containing 0.0584% hydrocortisone aceponate (HCA) on canine atopic dermatitis (CAD) and to evaluate the skin barrier function during the treatment of CAD. Twenty-one dogs that fulfilled the diagnostic criteria for CAD were included in this study.

Characteristics of Epstein-Barr virus isolated from the malignant lymphomas in Korea.

Epstein-Barr virus (EBV) is a common herpes virus linked to a variety of human neoplasms. In this study, the EBV detection was identified with the paraffin-embedded tissues from 62 non-Hodgkin's lymphomas, 20 Hodgkin's lymphomas, and 48 non-neoplastic tonsils, using PCR for EBNA-1 and EBER-1 mRNA in situ hybridization for EBER-1 mRNA. The isolates were analyzed for type 1/2, variants C/D and F/f, and LMP-1 30 bp deletion.
