Autophagy modulation is a potential therapeutic strategy for tongue squamous cell carcinoma (TSCC). Melatonin possesses significant anti-carcinogenic activity. However, whether melatonin induces autophagy and its roles in cell death in TSCC are unclear. Herein, we show that melatonin induced significant apoptosis in the TSCC cell line Cal27. Apart from the induction of apoptosis, we demonstrated that melatonin-induced autophagic flux in Cal27 cells as evidenced by the formation of GFP-LC3 puncta, and the upregulation of LC3-II and downregulation of SQSTM1/P62...

OBJECTIVES: To study the effect of the metabolic syndrome (MetS) on organ damage and mortality in patients with SLE. METHODS: Consecutive patients who fulfilled ≥4 ACR criteria for SLE were assessed for the MetS in October 2010. The MetS was defined by the updated joint consensus criteria, using the Asian criteria for central obesity. Longitudinal data on organ damage and mortality were retrieved. The association between MetS and new damage and mortality was studied by logistic regression...

BACKGROUND: Imbalanced cellular immunity is critical to the pathogenesis of systemic lupus erythematosus (SLE). Recently, autophagy has emerged as a key homeostatic mechanism in T lymphocytes. This study was conducted to explore the impact of autophagy on the Th17/ regulatory T (Treg) immune imbalance in SLE. METHODS: Peripheral Th17 and Treg cells from newly diagnosed patients with SLE and healthy controls were detected by flow cytometry. Additionally, the effects of chloroquine (CQ) autophagic inhibition on the Th17/Treg immune response were investigated in vitro...

Hydroxychloroquine (HCQ) is an immunosuppressive agent widely used in rheumatoid arthritis (RA). T follicular helper (Tfh) cells play a vital role in the pathogenesis of RA. However, whether HCQ suppresses arthritis development through interfering with Tfh cells have never been reported. To address this issue, we investigated the percent of Tfh cells in newly diagnosed RA patients and found that they were up-regulated in peripheral blood. Importantly, in ex vivo experiments of peripheral blood mononuclear cells (PBMCs) from healthy volunteers, we proved that the percentage of Tfh cells in PBMCs and purified CD4(+) T cells were decreased after HCQ treatment...

Tamoxifen is commonly used to treat patients with ESR/ER-positive breast cancer, but its therapeutic benefit is limited by the development of resistance. Recently, alterations in macroautophagy/autophagy function were demonstrated to be a potential mechanism for tamoxifen resistance. Although MTA1 (metastasis-associated 1) has been implicated in breast tumorigenesis and metastasis, its role in endocrine resistance has not been studied. Here, we report that the level of MTA1 expression was upregulated in the tamoxifen resistant breast cancer cell lines MCF7/TAMR and T47D/TR, and knockdown of MTA1 sensitized the cells to 4-hydroxytamoxifen (4OHT)...

Mycoplasma pneumoniae has been associated with respiratory tract infections. Mycoplasma pneumoniae pneumonia-related pleural effusion is rarely reported. Extra-pulmonary abnormalities such as encephalitis, myocarditis, glomerulonephritis, and myringitis have been reported. However pulmonary manifestations in systemic lupus erythematosus include pneumonitis, pleurisy, interstitial lung disease, and thromboembolic disease. We present the case of a 26-year-old male who came for evaluation of fever, cough, and shortness of breath with right-sided chest pain...

Treatment and outcome of systemic lupus erythematosus (SLE) in C1q deficient patients are rarely reported. The aim of this report is to share our experience about the course of management of three cases diagnosed as SLE with C1q deficiency, in light of present literature. Initial and dominant complaints of three cases from two different families were cutaneous manifestations. One patient was also diagnosed with arthritis and thrombocytopenia. Antinuclear antibody was positive in all cases, whereas anti-dsDNA was negative with normal levels of complement C3, C4 and decreased CH50 activity...

Hydroxychloroquine inhibits systemic inflammation and autophagy and may thus have antineoplastic effects [1]. We investigated the effect of hydroxychloroquine on cancer risk in patients with primary Sjögren syndrome(pSS). We used the Taiwan National Health Insurance Database to compare cancer incidence between incident pSS patients with or without at least 6-month hydroxychloroquine use within a 1- or 3-year period. Propensity score matched landmark analysis was used. We included 4194 alive patients without cancer 1 year after pSS diagnosis from 2000 through 2005...

Pro-inflammatory cytokines such as leptin and IL-6 play an important role in the development of cardiovascular risk. Determine the relationship between leptin and IL-6 concentrations with cardiovascular risk in patients with rheumatoid arthritis. We determined IL-6 and leptin levels in 77 patients with the diagnosis of rheumatoid arthritis. The cardiovascular risk was calculated using the modified Framingham scale. Statistical analysis was performed using SPSS 22 considering a significant p < 0.05. Serum leptin concentrations and cardiovascular risk (CVR) factors were compared and found that there was a significant difference between higher leptin values and disease activity (p 0...

The benefits of inhibiting autophagy in cancer are still controversial, with differences in outcome based on the type of tumor, the context and the particular stage of inhibition. Here, we investigated the impact of inhibiting autophagy at different stages on chemosensitivity using 3-dimensional (3D) models of mesothelioma, including ex vivo human tumor fragment spheroids. As shown by LC3B accumulation, we successfully inhibited autophagy using either an early stage ULK1/2 inhibitor (MRT 68921) or a late stage inhibitor (hydroxychloroquine)...

Lupus alopecia is usually difficult to treat. We report a case of a 40-year-old woman with Sjögren's syndrome and atopic dermatitis who presented with discoid lupus erythematosus on the forearms and lupus erythematosus profundus with alopecia involving the scalp. A biopsy specimen taken from the discoid lupus erythematosus lesion on the forearm further exhibited a xanthomatous reaction, which however was not detected in another specimen from the lupus erythematosus profundus on the scalp. Treatment with oral hydroxychloroquine showed dramatic effects and complete hair regrowth was obtained 3 months later...

Generally, the main complications of silicone implantation are local symptoms. However, some patients develop late-onset systemic symptoms often associated with a rare form of hyperactive immune response, as part of a syndrome known as autoimmune syndrome induced by adjuvants (ASIA). Reported cases of ASIA have shown resolution with explantation, but not with immunomodulatory therapy. In this report, we described a case of a previously healthy 23-year-old woman, who has undergone silicone breast implant augmentation, for aesthetic reasons, and developed localized cutaneous impairment 3 years postsurgery...
