Purpose: We provide evidence for the reclassification of the BRCA1:c.5017_5019del variant by presenting the clinicopathological characteristics, clinical outcomes, and family history of breast or ovarian cancer in 17 patients with this variant. Methods: This study included breast or ovarian cancer patients tested for BRCA1/2 genes between January 2008 and June 2020 at 10 medical centers in Korea. We retrospectively reviewed 17 probands from 15 families who had the BRCA1:c.5017_5019del variant according to the electronic medical records. Results: We present 10 breast cancer patients and 7 ovarian cancer patients from 15 families identified as having BRCA1:c.5017_5019del and a total of 19 cases of breast cancer and 14 cases of ovarian cancer in these families. The ratio of breast-to-ovarian cancer was 1.3:1. Breast cancer patients with this variant showed a rich family history of breast or ovarian cancer, 8 patients (80.0%). The mean age at diagnosis was 45.4 years and 6 patients (60.0%) were categorized into hormone-receptor–negative breast cancer. Also, the ovarian cancer patients with this variant showed strong family histories of breast and/or ovarian cancer in 4 patients (57.1%). Conclusion: We presented clinical evidence for the reclassification of BRCA1:c.5017_5019del as a likely pathogenic variant (LPV). Reclassification as LPV could result in the prophylactic treatment and medical surveillance of probands, family testing recommendations, and appropriate genetic counseling of their families.

Objectives: TSepsis and subsequent acute lung injury (ALI) is a critical state of health caused by infection or endotoxins. This study was conducted to evaluate the effect of Water Extract of Aconiti Lateralis Preparata Radix (AR) on lipopolysaccharide (LPS)-induced sepsis in C57BL/6 mice. Methods: Male C57BL/6 mice were intraperitoneally injected with LPS to induce sepsis and ALI. AR was orally fed twice at 30 min and 180 min after LPS injection. At 24 h post injection, mice were sacrificed, bronchoalveolar lavage fluid (BALF) and blood was collected, and lung tissue was harvested. Hematoxylin and eosin staining was performed in lung tissues, wet/dry ratio of the lung tissue was measured, and the serum cytokine and chemokine levels were analyzed. Results: AR revoked the LPS-induced pathological changes in lung tissues, such as abnormal histological structures, immune cell infiltration and lung edema. Also, AR suppressed the neutrophil infiltration into the lung which was greatly increased by LPS injection based on the cell content of collected BALF. Serum cytokines and chemokines were measured, and AR reversed the LPS-induced increase of cytokines such as interleukin 1 beta, interleukin 6, tumor necrosis factor alpha and chemokines including C-X-C motif chemokine ligand 1 and 2. Conclusion: TAR showed a protective effect in the pathological progress of LPS-induced ALI. Especially, AR suppressed lung edema and infiltration of neutrophils by inhibiting cytokine and chemokine expressions. Such results demonstrate the potential of AR as a therapeutic agent for sepsis and sepsis-induced ALI.

Background : The purpose of this study was to investigate the anti-inflammatory properties of stems and leaves of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (ES) from Gangwon-do. Methods and Results : Stems and leaves of ES were collected from two areas in Gangwon-do: Cheorwon-gun and Samcheok-si. Samples were extracted with water by using the pressurized liquid extraction method and with 70% prethanol A by using the heat reflux extraction method. The anti-inflammatory effects of ES were evaluated through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide(MTT), lactate dehydrogenase(LDH) assay, nitric oxide(NO) assay, enzyme-linked immunosorbent assay(ELISA), and Western blot analysis in RAW 264.7 macrophages stimulated with lipopolysaccharide (LPS). 1) Results showed that ES leaf extractions were not cytotoxic at a concentration of up to 30 ㎍/㎖. The leaves of 70% prethanol A extractions of ES(30 ㎍/㎖) inhibited NO, interleukin-6(IL-6), and tumor necrosis factor-α(TNF-α) production and decreased the protein level of cyclooxygenase 2(COX-2). There was no significant change in the protein level of inducible nitric oxide synthase(iNOS). The stem extractions of ES did not exhibit anti-inflammatory effects. Conclusions : In this study, the leaves of 70% prethanol A extractions of ES demonstrated anti-inflammatory effect on RAW 264.7 macrophages. The 70% prethanol A extractions have a relatively higher anti-inflammatory effect on RAW 264.7 macrophages than water extractions.
