Abstract
Little information exists on YKL-40-a key protein in tissue remodeling-and complete blood count (CBC) parameters during acute exacerbations of advanced chronic obstructive pulmonary disease (COPD). This pilot exploratory study (August 2020-January 2021) investigated the connection between serum YKL-40 levels and CBC profile in sex- and age-matched individuals with severe COPD (GOLD stage III, n = 23, median age = 66 years, 65.21% males) and very severe COPD (GOLD stage IV, n = 24, median age = 66.5 years, 74.81% males). The measured parameters were serum YKL-40, absolute leukocyte count (ALLC), absolute neutrophil count (ANC), neutrophil percentage, absolute lymphocyte count (ALC), lymphocyte percentage, neutrophil-to-lymphocyte ratio (NLR), absolute eosinophil count (AEC), eosinophil percentage, absolute monocyte count (AMC), monocyte percentage, absolute basophil count (ABC), basophil percentage, hemoglobin levels, and hematocrit concentrations. No significant inter-group differences were observed. However, high YKL-40 subjects (n = 23)-as stratified via median YKL-40 (3934.5 pg/mL)-showed significantly increased neutrophil percentage and NLR but significantly lower lymphocyte-, eosinophil-, and basophil-related parameters compared to low YKL-40 patients (n = 24). These results reveal multidimensional, YKL-40-associated changes in leukocyte profile of patients with advanced COPD during acute exacerbations, with potential implications for personalized treatment.

Cell Survival Failure in Effector T Cells From Patients With Systemic Lupus Erythematosus Following Insufficient Up-Regulation of Cold-Shock Y-Box Binding Protein 1. Arthritis Rheumatol 2020; 72:1721-1733. [PMID: 32475063 DOI: 10.1002/art.41382] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Accepted: 04/23/2020] [Indexed: 12/11/2022]
Abstract
OBJECTIVE The importance of cold-shock Y-box binding protein 1 (YB-1) for cell homeostasis is well-documented based on prior observations of its association with certain cancer entities. This study was undertaken to explore the role of YB-1 in T cell homeostasis and survival and the potential contribution of YB-1 to the pathogenesis of systemic lupus erythematosus (SLE). METHODS In the peripheral blood from 25 SLE patients and 25 healthy donors, the expression of YB-1 and frequency of T cell apoptosis was analyzed by quantitative polymerase chain reaction (qPCR) and fluorescence-activated cell sorting of CD4+ T cells ex vivo and also analyzed in T cells in vitro after 6 days of stimulation with anti-CD3-coupled or anti-CD3/anti-CD28-coupled microspheres. YB-1 was overexpressed using lentiviral transduction with wild-type green fluorescent protein (wtGFP) YB-1, and knockdown of YB-1 was achieved using specific short hairpin RNA (shRNA) (3-fold reduction; P < 0.0001). RESULTS YB-1 expression was significantly lower in apoptosis-prone T cells and in activated T cells from SLE patients compared to YB-1 expression in nonapoptotic T cells and activated T cells from healthy donors (P = 0.001). Knockdown of YB-1 in T cells consequently led to expression of proapoptotic molecules and caspase 3 activation (1.6-fold), and subsequently, to apoptosis. Furthermore, YB-1 promoted survival pathways involving enhanced protein expression of the kinase Akt (2-fold) and Bcl-2 (3-fold), even when Fas/CD95 was triggered. YB-1-mediated T cell survival was reversed by Akt and phosphatidylinositol 3-kinase (PI3K) inactivation. In SLE patients, rescue of YB-1 expression strongly promoted survival of T cells and even prevented cell death in T cells that were extremely apoptosis-prone. CONCLUSION Our data show that failure of YB-1 up-regulation in T cells from SLE patients led to enhanced apoptosis. These findings imply that YB-1 plays a crucial role in the disturbed homeostasis of activated T cells leading to hematopoietic alterations in SLE. These insights may help facilitate the development of new treatment strategies for SLE.

Abstract
Background Papillary thyroid carcinoma (PTC) is an indolent tumor that is exploding with increasing thyroid nodules (TN). Environmental carcinogens, lifestyle changes increased the incidence of thyroid carcinoma. With the development of B-ultrasound imaging, more and more thyroid cancer has been found. There has been a debate about whether thyroid cancer is overtreated. Methods The expression of T cell subsets and plasma cytokines in 191 patients, including 79 patients with PTC (PTC group), 58 patients with thyroid nodules (TN group) and 54 healthy individuals (HP group) were analyzed by flow cytometry. Results High levels of natural killer cells (NK) were detected in PTC and TN groups than in HP group. High activities of CD8+HLA-DR+ and CD8+CD38+ showed a gradual upward trend from HP group to PTC group. The rise in the levels of TNF-α in PTC patients’ was evident when compared with HP group. CD8+CD38+ showed a significant correlation with lymph node metastasis. CD8+CD38+ co-expression was higher in Nx stage than N0 stage, while the proportion of IL-10 was dramatically decreased in the Nx stage. Conclusions These results indicated that CD8+CD38+ might act as a biomarker of PTC lymph node metastasis. The combination of CD8+HLA-DR+, CD8+CD38+ and TNF-α can be used as useful biomarkers for the early-warning indicator of PTC.

Abstract
Hematologic malignancy is a serious disease that develops quickly and aggressively, severely threatening human health owing to its high mortality. The current study aimed to evaluate the antitumor effects of isoferulic acid (IFA) on leukemia cells and investigate the possible molecular mechanisms. Hematologic cancer cell lines (Raji, K562 and Jurkat) were treated with IFA in a dose‑dependent manner and proliferation was measured by a cell proliferation assay. Cell cycle arrest was detected via flow cytometry using propidium iodide (PI) staining. Cell apoptosis and apoptosis‑associated signal pathways were analyzed via Annexin V/PI staining and western blot assays, respectively. IFA inhibited cell viability, induced cell apoptosis and triggered cell cycle arrest in G2/M phase in Raji, K562, and Jurkat cells in a dose‑dependent manner. In response to IFA treatment, the levels of cleaved poly(ADP‑ribose) polymerase and cleaved caspase‑3 were increased in Jurkat and K562 cells, which was associated with increased phosphorylation of Cdc2 and reduction of Cyclin B1 levels. IFA remarkably attenuated the phosphorylation of mTOR and Akt in Jurkat cells. Collectively, the present data suggested that IFA had therapeutic effects on Jurkat, K562, and Raji cells, indicating it as a promising candidate for the treatment of hematologic malignancy.

Abstract
COPD is characterized by a pulmonary and systemic inflammatory process. Several authors have reported the elevation of multiple inflammatory markers in patients with COPD; however, their use in routine clinical practice has limitations. The neutrophil-to-lymphocyte ratio (NLR) is a useful and cost-effective inflammatory marker derived from routine complete blood count. We performed a systematic literature review using the PRISMA statement. Twenty-two articles were included, recruiting 7,601 COPD patients and 784 healthy controls. Compared with controls, COPD patients had significantly higher NLR values. We found a significant correlation between the NLR and clinical/functional parameters (FEV1, mMRC, and BODE index) in COPD patients. Elevation of the NLR is associated with the diagnosis of acute exacerbation of COPD (pooled data propose a cut-off value of 3.34 with a median sensitivity, specificity, and area under the curve of 80%, 86%, and 0.86, respectively). Additionally, increased NLR is also associated with the diagnosis of a bacterial infection in exacerbated patients, with a cut-off value of 7.30, although with a low sensitivity and specificity. The NLR is an independent predictor of in-hospital and late mortality after exacerbation. In conclusion, the NLR could be a useful marker in COPD patients; however, further studies are needed to better identify the clinical value of the NLR.
