SERPINB3/B4 Is Increased in Psoriasis and Rosacea Lesions and Has Proinflammatory Effects in Mouse Models of these Diseases.

Psoriasis and rosacea are both chronic inflammatory skin disorders resulted from aberrant keratinocyte-immune cell crosstalk, but the common molecular foundations for these 2 conditions are poorly understood. In this study, we reveal that both patients with psoriasis and those with rosacea as well as their mouse models have significantly elevated expressions of SERPINB3/B4 (members of serine protease inhibitor) in the lesional skin. Skin inflammation in mice that resembles both psoriasis and rosacea is prevented by SERPINB3/B4 deficiency.

A safe and effective endoscopic treatment method for simple hepatic cysts (with video).

Symptomatic simple hepatic cysts require treatment, with several guidelines recommending laparoscopic deroofing. However, cysts located in the posterosuperior segments are considered poor candidates for this procedure. Gastrointestinal endoscopes are more flexible and able to reach less accessible areas than laparoscopes.

Identification of prospective aging drug targets via Mendelian randomization analysis.

Calpain Inhibitor Calpeptin Improves Pancreatic Fibrosis in Mice with Chronic Pancreatitis by Inhibiting the Activation of Pancreatic Stellate Cells.

Background: Pancreatic fibrosis is a hallmark feature of chronic pancreatitis (CP), resulting in persistent damage to the pancreas. The sustained activation of pancreatic stellate cells (PSCs) plays a pivotal role in the progression of pancreatic fibrosis and is a major source of extracellular matrix (ECM) deposition during pancreatic injury.

Methods: Calpain is a calcium-independent lysosomal neutral cysteine endopeptidase and was found to be correlated to various fibrotic diseases.

Erratum: Shikonin induces apoptosis and necroptosis in pancreatic cancer via regulating the expression of RIP1/RIP3 and synergizes the activity of gemcitabine.

[This corrects the article on p. 5507 in vol. 9, PMID: 29312502.

TI17, a novel compound, exerts anti-MM activity by impairing Trip13 function of DSBs repair and enhancing DNA damage.

Background: Thyroid hormone receptor interacting protein 13 (Trip13) is an AAA-ATPase that regulates the assembly or disassembly protein complexes and mediates Double-strand breaks (DSBs) repair. Overexpression of Trip13 has been detected in many cancers and is associated with myeloma progression, disease relapse and poor prognosis inmultiple myeloma (MM).

Methods: We have identified a small molecular, TI17, through a parallel compound-centric approach, which specifically targets Trip13.

Targeting Aquaporin-3 Attenuates Skin Inflammation in Rosacea.

Rosacea is a common inflammatory skin disorder mediated by the dysregulation of both keratinocytes and T cells. Here, we report that aquaporin 3 (AQP3), a channel protein that mediates the transport of water/glycerol, was highly expressed in the epidermis and CD4 T cells of both rosacea patients and experimental mice. Specifically, AQP3 deletion blocked the development of rosacea-like skin inflammation in model mice with LL37-induced rosacea-like disease.

TLR7 promotes skin inflammation via activating NFκB-mTORC1 axis in rosacea.

Rosacea is a chronic inflammatory skin disease originated from damaged skin barrier and innate/adaptive immune dysregulation. Toll-like receptors (TLRs) sense injured skin and initiate downstream inflammatory and immune responses, whose role in rosacea is not fully understood. Here, via RNA-sequencing analysis, we found that the TLR signaling pathway is the top-ranked signaling pathway enriched in rosacea skin lesions, in which TLR7 is highlighted and positively correlated with the inflammation severity of disease.

Integrated Omics Reveal the Molecular Characterization and Pathogenic Mechanism of Rosacea.

Recent efforts have described the transcriptomic landscape of rosacea. However, little is known about its proteomic characteristics.

Efficacy and safety of antibiotic agents in the treatment of rosacea: a systemic network meta-analysis.

Antibiotics are considered the backbone of rosacea management, especially for controlling inflammatory papules and pustules. We aim to evaluate the efficacy and safety of varied prescriptions and doses of antibiotics in treating rosacea by network meta-analysis. In this study, we compared all available randomized controlled trials (RCTs) that have studied systemic and topical antibiotics and placebo in rosacea therapy.

Fenbufen Alleviates Severe Acute Pancreatitis by Suppressing Caspase-1/Caspase-11-mediated Pyroptosis in Mice.

Aim: In the present study, we aimed to investigate the effects of Fenbufen treatment on the SAP model induced by caerulein and lipopolysaccharide.

Background: Severe acute pancreatitis (SAP) is an extremely dangerous disease with high mortality, which is associated with inflammatory response and acinar cell death. The caspase family plays an important role in cell death, such as caspase-1 and caspase-11 in pyroptosis.

NAT10-mediated AXL mRNA N4-acetylcytidine modification promotes pancreatic carcinoma progression.

Although the patient's survival time in various cancers has significantly increased in recent decades, the overall 5-year survival rate of pancreatic ductal adenocarcinoma (PDAC) has remained virtually unchanged due to rapid progression and metastasis. While N-acetyltransferase 10 (NAT10) has been identified as a regulator of mRNA acetylation in many malignancies, its role in PDAC remains unclear. Here, we found that NAT10 mRNA and protein levels were upregulated in PDAC tissues.

Aberrant amino acid metabolism promotes neurovascular reactivity in rosacea.

Rosacea is a chronic skin disorder characterized by abnormal neurovascular and inflammatory conditions on the central face. Despite increasing evidence suggesting that rosacea is associated with metabolic disorders, the role of metabolism in rosacea pathogenesis remains unknown. Here, via a targeted metabolomics approach, we characterized significantly altered metabolic signatures in patients with rosacea, especially for amino acid-related metabolic pathways.

Lithocholic acid promotes rosacea-like skin inflammation via G protein-coupled bile acid receptor 1.

Background: Rosacea is a chronic inflammatory skin disorder with unclear etiology. Evidence showed that immunoinflammatory dysregulation was involved in the pathogenesis. Bile acids, as important participants of hepatoenteric circulation, play a vital role in immunoinflammatory regulation through peripheral blood circulation.

Mediation roles of neutrophils and high-density lipoprotein (HDL) on the relationship between HLA-DQB1 and rosacea.

Background: Though the previous genome-wide association studies found the association between alleles and rosacea in the European populations, the data is lacking among the Asians. Moreover, neutrophils are important in the immune-related mechanism of rosacea, and dyslipidemia is closely related to rosacea. We aimed to explore the association between genes and rosacea in Chinese rosacea patients, as well as the mediation effect of neutrophils, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) on the relationship between genes and rosacea.

Increased serum levels of CCL3, CXCL8, CXCL9, and CXCL10 in rosacea patients and their correlation with disease severity.

Rosacea is a common chronic inflammatory skin disease involving millions of patients worldwide. Previous studies have highlighted the upregulation of a variety of chemokines in the skin lesions of both rosacea patient and rosacea-like mouse model. However, the serum levels of these chemokines and their clinical significance have not been explored before.

Androgen Receptor-Mediated Paracrine Signaling Induces Regression of Blood Vessels in the Dermal Papilla in Androgenetic Alopecia.

Androgenetic alopecia (AGA), also known as male pattern baldness, is associated with androgen and androgen receptor (AR) signaling; however, the pathogenesis of AGA remains largely unknown. In this study, we show that nuclear localization of AR is elevated in the dermal papilla (DP) of balding scalp in patients with AGA. Transcriptome analysis identifies microvascular abnormalities in the DP of balding scalp compared with nonbalding scalp of patients with AGA.
