As a result of mutations in the upstream components of the Wnt/β-catenin signaling pathway, this cascade is abnormally activated in colon cancer. Hence, identifying the activation mechanism of this pathway is an urgent need for the treatment of colon cancer. Here, we found an increase in ADCK1 (AarF domain-containing kinase 1) expression in clinical specimens of colon cancer and animal models. Upregulation of ADCK1 expression promoted the colony formation and infiltration of cancer cells. Downregulation of ADCK1 expression inhibited the colony formation and infiltration of cancer cells, in vivo tumorigenesis, migration, and organoid formation. Molecular mechanistic studies demonstrated that ADCK1 interacted with TCF4 (T-cell factor 4) to activate the β-catenin/TCF signaling pathway. In conclusion, our research revealed the functions of ADCK1 in the development of colon cancer and provided potential therapeutic targets.In the early 1990s, it has been described that LTα and LTβ form LTα2β and LTαβ2 heterotrimers, which bind to TNFR1 and LTβR, respectively. Afterwards, the LTαβ2-LTβR system has been intensively studied while the LTα2β-TNFR1 interaction has been ignored to date, presumably due to the fact that at the time of identification of the LTα2β-TNFR1 interaction one knew already two ligands for TNFR1, namely TNF and LTα. Here, we show that LTα2β interacts not only with TNFR1 but also with TNFR2. We furthermore demonstrate that membrane-bound LTα2β (memLTα2β), despite its asymmetric structure, stimulates TNFR1 and TNFR2 signaling. Not surprising in view of its ability to interact with TNFR2, LTα2β is inhibited by Etanercept, which is approved for the treatment of rheumatoid arthritis and also inhibits TNF and LTα.Aberrant long-noncoding RNA (lncRNA) expression has been shown to be involved in the pathogenesis of endometrial cancer (EC). Herein, we report a novel tumor suppressor lncRNA SOCS2-AS1 in EC. Quantitative real-time PCR was performed to detect RNA expression. In situ hybridization and nuclear/cytoplasmic fractionation assays were used to detect the subcellular location. We found that SOCS2-AS1 was downregulated in EC tissues. Its reduced expression was correlated with advanced clinical stage and poor prognosis. Forced expression of SOCS2-AS1 suppressed EC cell proliferation and induced cell-cycle arrest and apoptosis. SOCS2-AS1-binding proteins were detected using RNA pull-down assay and mass spectrometry. Mechanistically, SOCS2-AS1 bound to Aurora kinase A (AURKA) and increased its degradation through the ubiquitin-proteasome pathway. In conclusion, SOCS2-AS1 may thus serve as a prognostic predictor and a biomarker for AURKA-inhibitor treatment in EC patients.Chimeric antigen receptor (CAR)-T cell therapy is a revolutionary new pillar in cancer treatment. Although treatment with CAR-T cells has produced remarkable clinical responses with certain subsets of B cell leukemia or lymphoma, many challenges limit the therapeutic efficacy of CAR-T cells in solid tumors and hematological malignancies. Barriers to effective CAR-T cell therapy include severe life-threatening toxicities, modest anti-tumor activity, antigen escape, restricted trafficking, and limited tumor infiltration. In addition, the host and tumor microenvironment interactions with CAR-T cells critically alter CAR-T cell function. Furthermore, a complex workforce is required to develop and implement these treatments. In order to overcome these significant challenges, innovative strategies and approaches to engineer more powerful CAR-T cells with improved anti-tumor activity and decreased toxicity are necessary. In this review, we discuss recent innovations in CAR-T cell engineering to improve clinical efficacy in both hematological malignancy and solid tumors and strategies to overcome limitations of CAR-T cell therapy in both hematological malignancy and solid tumors.Although the mixed lineage leukemia 5 (MLL5) gene has prognostic implications in acute promyelocyte leukemia (APL), the underlying mechanism remains to be elucidated. Here, we demonstrate the critical role exerted by MLL5 in APL regarding cell proliferation and resistance to drug-induced apoptosis, through mtROS regulation. Additionally, MLL5 overexpression increased the responsiveness of APL leukemic cells to all-trans retinoic acid (ATRA)-induced differentiation, via regulation of the epigenetic modifiers SETD7 and LSD1. In silico analysis indicated that APL blasts with MLL5high transcript levels were associated with retinoic acid binding and downstream signaling, while MLL5low blasts displayed decreased expression of epigenetic modifiers (such as KMT2C, PHF8 and ARID4A). Finally, APL xenograft transplants demonstrated improved engraftment of MLL5-expressing cells and increased myeloid differentiation over time. Concordantly, evaluation of engrafted blasts revealed increased responsiveness of MLL5-expressing cells to ATRA-induced granulocytic differentiation. Together, we describe the epigenetic changes triggered by the interaction of MLL5 and ATRA resulting in enhanced granulocytic differentiation.

MoMo is a mortality monitoring system that guides public health policy in Spain. The COVID-19 pandemic worsened death notification delays, thus biasing downwards the daily (cumulative) excess mortality estimates produced by MoMo. The goal of this study is to find the best model to correct these estimates for the effect of death notification delays.

The process followed was 1) estimates for the excess mortality accumulated in Spain since the beginning of the COVID-19 pandemic are published daily by MoMo and gathered in this study for the period 15/04/2020-25/05/2020. 2) the intensity of daily revisions is computed as the ratio of the estimate published each day divided by the estimate published the day before. 3) Adjusted excess mortality estimates result from applying to these ratios five different correcting models (a simple arithmetic mean or a weighted average, as well as linear, quadratic and cubic regressions). 4) The performance of these corrected estimates is compared with the definite values using the root mean square error (RMSE).

The intensity of daily revisions for the cumulative excess of deaths fell to 1 (no revision) as the publication date left behind the date of death. The correcting estimates based on polynomial regressions reduced the error with respect to the definite observed values by 18-25%.

To improve the validity of the daily estimates for the cumulative excess of deaths from MoMo, it is recommended to correct the notification delay of deaths using polynomial regression models estimated with data on previous revisions.

Just like any other sensitivity reaction, the severity can vary from mild to moderate skin manifestations such as erythematous rash to an even more severe presentation or life-threatening event, such as angioedema and anaphylaxis. CASE REPORT This case report discusses a patient who presented to our institution with a diffuse complex rash 2 days after undergoing CT scan imaging with intravenous iodine contrast injection. The rash started by being maculopapular in nature. Later on, the patient developed a purpuric and petechial pattern, and eventually, an acute exanthematous pustulosis rash was noticed. Several attempts to treat the patient with intravenous corticosteroids failed. Three days after admission (5 days after the rash started), topical steroids were used in place of parenteral steroids. The rash showed remarkable improvement in a very short time. The patient was diagnosed with delayed hypersensitivity IV iodine reaction, resistant to parenteral corticosteroids. The workup of such an extensive rash and odd presentation include several laboratory tests and skin testing to be able to rule out more serious differential diagnoses. CONCLUSIONS This case is unique as it enables us to show the importance of substituting topical management, more specifically, topical steroids that might even replace parenteral steroids, to our management in order to treat allergic reactions, especially in the presence of a rash.BACKGROUND In addition to sociodemographic and COVID-19- related factors, the needs of school support, including material, psychological and information support, have seldom been discussed as factors influencing anxiety and depression among college students during the COVID-19 pandemic. MATERIAL AND METHODS In this cross-sectional study, 3351 college students from China were surveyed through questionnaires about their sociodemographic and COVID-19 characteristics, the needs of school support, and their experiences with anxiety and depression. RESULTS Anxiety and depression were reported by 6.88% and 10.50% of students, respectively. Married, higher education, non-medical, and urban students had significantly higher risks of anxiety or depression. Additionally, symptoms such as cough and fever, especially when following a possible contact with suspected individuals, quarantine history of a personal contact, going out 1-3 times a week, not wearing a mask, and spending 2-3 hours browsing COVID-19-related information were significantly associated with the occurrence of anxiety or depression. Those who used methods to regulate their emotional state, used a psychological hotline, and who had visited a psychiatrist showed higher anxiety or depression. Those who used online curricula and books, used preventive methods for COVID-19, and who had real-time information about the epidemic situation of the school showed lower anxiety and depression. CONCLUSIONS In addition to sociodemographic and COVID-19-related aspects, students' needs for psychological assistance and information from schools were also associated with anxiety and depression among college students.

The objective of this study was to investigate the effects of inverted photoperiods on the blood pressure and carotid arteries in spontaneously hypertensive rats (SHRs) and Wistar-Kyoto (WKY) rats (homologous control group).

This study used two inverted photoperiods [inverted lightdark (ILD)16  8 and ILD12  12] to create the model. A total of 27 male SHR and 27 male WKY rats were randomly divided into six groups (nine rats per group) SHR (LD12  12), SHR (ILD16  8), SHR (ILD12  12), WKY (LD12  12), WKY (ILD16  8) and WKY (ILD12  12). We recorded the trajectory of the activity rhythm of the rats and performed carotid vascular ultrasound examination, MRI (arterial spin labelling) analysis and carotid biopsy. The results showed that inverted photoperiods increased the blood pressure, carotid intima-media thickness, resistance index and blood flow velocity. CB-5083 inhibitor In addition, inverted photoperiods led to the development of carotid arterial thrombosis, significantly reduced cerebral blood flow and increased the number of collagen fibres. Moreover, it increased the expression of angiotensin receptor and low-density lipoprotein receptor in the carotid arteries, leading to decreased expression of 3-hydroxy-3-methylglutaryl-Coenzyme A reductase and nitric oxide synthase. Inverted photoperiods induced the formation of atherosclerotic plaque. Multiple results of SHR were worse than those of WKY rats.

Taken together, inverted photoperiods can produce a series of adverse consequences on blood pressure and carotid arteries. Hypertension can aggravate the adverse effects of inverted photoperiods.
