    Abstract Purpose: The purpose of this study was to evaluate the efficacy and safety of red ginseng oil (RXGIN) in men with lower urinary tract symptoms. Materials and Methods: Men aged between 40 and 75 years with a total International Prostate Symptom Score (IPSS) of 8 to 19 points were recruited from April 2020 to December 2020. Subjects were randomly assigned to either the RXGIN group or the control group in a 1:1 ratio and received either RXGIN or placebo daily for 12 weeks. For the primary outcome, changes in IPSS scores at 6 and 12 weeks from baseline were analyzed. The secondary outcomes were changes in International Index of Erectile Function (IIEF), maximum urinary flow rate, and post-void residual volume at weeks 6 and 12 compared to baseline. Urine analysis and blood tests were additionally performed for safety assessment. Results: A total of 88 subjects (RXGIN group, 46; control group, 42) completed the study. The total IPSS and IPSS subscores (residual urine sensation, frequency, intermittency, urgency, weak stream, straining, nocturia, and quality of life) were significantly improved in the RXGIN group compared to the control group at weeks 6 and 12. Total IIEF and sexual desire were significantly improved in the RXGIN group at week 6 and week 12, respectively, but there were no significant changes in the level of serum testosterone or dihydrotestosterone. The serum prostate-specific antigen showed significant decrease at weeks 12. No serious adverse events leading to discontinuation of the study drug were observed in the RXGIN group. Conclusions: Red ginseng oil (RXGIN) appears to be safe and effective in improving lower urinary tract symptoms in men and may also improve some aspects of sexual function.

    Abstract Receptor-interacting protein kinase 3 (RIPK3) is the primary regulator of necroptotic cell death. RIPK3 expression is often silenced in various cancer cells, which suggests that it may have tumor suppressor properties. However, the exact mechanism by which RIPK3 negatively regulates cancer development and progression remains unclear. This report indicates that RIPK3 acts as a potent regulator of the homeostatic proliferation of CD4

    Abstract Benign prostatic hyperplasia (BPH) is a disease characterized by abnormal proliferation of the prostate, which occurs frequently in middle-aged men. In this study, we report the effect of red ginseng oil (KGC11o) on BPH.The BPH-induced Sprague-Dawley rats were divided into seven groups: control, BPH, KGC11o 25, 50, 100, 200, and finasteride groups. KGC11o and finasteride were administered for 8 weeks. The BPH biomarkers, DHT, 5AR1, and 5AR2, androgen receptor, prostate-specific antigen (PSA), Bax, Bcl-2, and TGF-β were determined in the serum and prostate tissue. The cell viability after KGC11o treatment was determined using BPH-1 cells, and, androgen receptor, Bax, Bcl-2, and TGF-β were confirmed by western blotting.In the in vivo study, administration of KGC11o reduced prostate weight by 18%, suppressed DHT (up to 22%) and 5AR2 (up to 12%) levels from administration of 100 mg/kg KGC11o (P < 0.05). PSA was significantly downregulated dose-dependently from at the concentration of 50 mg/kg KGC11o (P < 0.05). BPH-1 cell viability significantly reduced through the treatment with KGC11o. In vitro and vivo, AR, Bcl-2 TGF-β levels reduced significantly but Bax was increased (P < 0.05).These results suggest that KGC11o may inhibit the development of BPH by significantly reducing the levels of BPH biomarkers via 5ARI, anti-androgenic effect, and anti-proliferation effect, serving as a potential functional food for treating BPH.

    Abstract Abstract TNF receptor-associated death domain (TRADD) is an essential mediator of TNF receptor signaling, and serves as an adaptor to recruit other effectors. TRADD has been shown to cycle between the cytoplasm and nucleus due to its nuclear localization (NLS) and export sequences (NES). However, the underlying function of nuclear TRADD is poorly understood. Here we demonstrate that cytoplasmic TRADD translocates to DNA double-strand break sites (DSBs) during the DNA damage response (DDR). Deficiency of TRADD or its sequestration in cytosol leads to accumulation of γH2AX-positive foci in response to DNA damage, which is reversed by nuclear TRADD expression. TRADD facilitates non-homologous end-joining (NHEJ) by recruiting NHEJ repair factors 53BP1 and Ku70/80 complex, whereas TRADD is dispensable for homologous recombination (HR) repair. Finally, an impaired nuclear localization of TRADD triggers cell death through the persistent activation of JNK and accumulation of reactive oxygen species (ROS). Thus, our findings suggest that translocation of TRADD to DSBs into the nucleus contributes to cell survival in response to DNA damage through an activation of DNA damage repair.

    Abstract Recently, several clinical studies reported that the photodynamic therapy (PDT) has photorejuvenation effects on the aged skin. Previously, our group introduced evidence of direct effect of PDT on cultured fibroblast (FB). PDT directly stimulated FBs and induced collagen synthesis through activation of extracellular signal-regulated kinase. In this study, we investigated indirect effect of PDT on the human dermal FB during photorejuvenation focused on the epithelial-mesenchymal interaction between keratinocyte (KC) and FB. The "low-level PDT" condition was used for PDT therapy to the cultured KC. Various kinds of cytokines in the supernatants of KC were evaluated by enzyme-linked immunosorbent assay. FBs were stimulated with the KC-conditioned medium (KCM) taken after PDT. The mRNA level of matrix metalloproteinases (MMPs), transforming growth factor (TGF)-β and collagen type Iα in the FB, was determined by real-time polymerase chain reaction. Clinical phtorejuvenation effect was also evaluated from nine patients who had PDT to treat actinic keratoses. Among the FB-stimulating cytokines, a significant elevation of interleukin (IL)-1α, IL-6, and tumor necrosis factor-α level in KCM was noted after PDT compared with controls. After stimulating FB with KCM, the mRNA of MMP-1 was decreased and the mRNA of collagen type Iα was increased compare to control. Clinically, fine wrinkles significantly reduced after PDT. However, coarse wrinkles were not recovered significantly. In conclusion, increased collagen synthesis may be mediated not only by direct effect of PDT on FB but also by indirect effect of PDT on FB through cytokines from KC, such as IL-1α, IL-6, and tumor necrosis factor-α.

    Abstract The dissemination of circulating tumor cells (CTCs) requires the Epithelial-to-Mesenchymal transition (EMT), in which cells lose their epithelial characteristics and acquire more mesenchymal-like phenotypes. Current isolation of CTCs relies on affinity-based approaches reliant on the expression of Epithelial Cell Adhesion Molecule (EpCAM). Here we show EMT-induced breast cancer cells maintained in prolonged mammosphere culture conditions possess increased EMT markers and cancer stem cell markers, as well as reduced cell mass and size by quantitative phase microscopy; however, EpCAM expression is dramatically decreased in these cells. Moreover, CTCs isolated from breast cancer patients using a label-free microfluidic flow fractionation device had differing expression patterns of EpCAM, indicating that affinity approaches reliant on EpCAM expression may underestimate CTC number and potentially miss critical subpopulations. Further characterization of CTCs, including low-EpCAM populations, using this technology may improve detection techniques and cancer diagnosis, ultimately improving cancer treatment.

    Abstract Ginseng is believed to have antitumor activity. Autophagy is largely a prosurvival cellular process that is activated in response to cellular stressors, including cytotoxic chemotherapy; therefore, agents that inhibit autophagy can be used as chemosensitizers in cancer treatment. We examined the ability of Korean Red Ginseng extract (RGE) to prevent autophagic flux and to make hepatocellular carcinoma (HCC) cells become more sensitive to doxorubicin.The cytotoxic effects of total RGE or its saponin fraction (RGS) on HCC cells were examined by the lactate dehydrogenase assay in a dose- or time-dependent manner. The effect of RGE or RGS on autophagy was measured by analyzing microtubule-associated protein 1A/1B-light chain (LC)3-II expression and LC3 puncta formation in HCC cells. Late-stage autophagy suppression was tested using tandem-labeled green fluorescent protein (GFP)–monomeric red fluorescent protein (mRFP)–LC3.RGE markedly increased the amount of LC3-II, but green and red puncta in tandem-labeled GFP–mRFP–LC3 remained colocalized over time, indicating that RGE inhibited autophagy at a late stage. Suppression of autophagy through knockdown of key ATG genes increased doxorubicin-induced cell death, suggesting that autophagy induced by doxorubicin has a protective function in HCC. Finally, RGE and RGS markedly sensitized HCC cells, (but not normal liver cells), to doxorubicin-induced cell death.Our data suggest that inhibition of late-stage autophagic flux by RGE is important for its potentiation of doxorubicin-induced cancer cell death. Therapy combining RGE with doxorubicin could serve as an effective strategy in the treatment of HCC.
