LncRNA H19 Participates in Leukemia Inhibitory Factor Mediated Stemness Promotion in Colorectal Cancer Cells.

Colorectal cancer (CRC) is a common human malignancy and the third leading cause of cancer-related death worldwide. Cancer stem cells (CSCs) were considered to play important roles in the genesis and development of many tumors. In recent years, it has been observed that leukemia inhibitory factor (LIF) might be involved in the regulation of stemness in cancer cells.

Incubation study on remediation of nitrate-contaminated soil by Chroococcus sp.

The possibility of using the non-nitrogen-fixing cyanobacterium (Chroococcus sp.) for the reduction of soil nitrate contamination was tested through Petri dish experiments. The application of 0.

Expression of CD44 is regulated by ELF3 in 5-FU treated colorectal cancer cells.

The development of chemoresistance in colorectal cancer (CRC) cells was usually thought to be inevitable as a result of continuing exposure to chemotherapeutic drugs. The existence of cancer stem cells (CSCs) within CRC tissues was recently suggested to play importance roles for this process. In this study, in order to mimic a dose schedule used in clinic (continuous infusion), low dose of fluorouracil (IC of 5-FU) was used to treat CRC cells.

The function of MSP-activated γδT cells in hepatocellular carcinoma.

Immunotherapeutic strategies targeting γδT cells are now recognized as a promising treatment method for hepatocellular carcinoma (HCC). To date, no specific antigen or antigenic epitope recognized by γδT cells has been identified, limiting their application in the field of HCC treatment. Previously, we used an established screening strategy to identify a novel HCC protein antigen recognized by γδT cells called MSP.

Characterization of endophytic bacteriome diversity and associated beneficial bacteria inhabiting a macrophyte .

Introduction: The endosphere of a plant is an interface containing a thriving community of endobacteria that can affect plant growth and potential for bioremediation. is an aquatic macrophyte, adapted to estuarine and freshwater ecosystems, which harbors a diverse bacterial community. Despite this, we currently lack a predictive understanding of how taxonomically structure the endobacterial community assemblies across distinct habitats (root, stem, and leaf).

OX40L-expressing recombinant modified vaccinia virus Ankara induces potent antitumor immunity via reprogramming Tregs.

Effective depletion of immune suppressive regulatory T cells (Tregs) in the tumor microenvironment without triggering systemic autoimmunity is an important strategy for cancer immunotherapy. Modified vaccinia virus Ankara (MVA) is a highly attenuated, non-replicative vaccinia virus with a long history of human use. Here, we report rational engineering of an immune-activating recombinant MVA (rMVA, MVA∆E5R-Flt3L-OX40L) with deletion of the vaccinia E5R gene (encoding an inhibitor of the DNA sensor cyclic GMP-AMP synthase, cGAS) and expression of two membrane-anchored transgenes, Flt3L and OX40L.

Efficacy of immunotherapy with combination of cryotherapy and topical imiquimod for treatment of Kaposi sarcoma.

Multiple treatment modalities for Kaposi sarcoma (KS) have been reported, including chemotherapy, radiation therapy, surgical excision, electrochemotherapy, and cryotherapy. Common topical treatments include timolol, imiquimod, and alitretinoin. We searched our institutional database for patients with ICD-9 or 10 codes for KS seen by a dermatologist with experience in KS management from July 1, 2004 to January 1, 2022.

In vivo tumor immune microenvironment phenotypes correlate with inflammation and vasculature to predict immunotherapy response.

Response to immunotherapies can be variable and unpredictable. Pathology-based phenotyping of tumors into 'hot' and 'cold' is static, relying solely on T-cell infiltration in single-time single-site biopsies, resulting in suboptimal treatment response prediction. Dynamic vascular events (tumor angiogenesis, leukocyte trafficking) within tumor immune microenvironment (TiME) also influence anti-tumor immunity and treatment response.

Spammer detection using multi-classifier information fusion based on evidential reasoning rule.

Spammer detection is essentially a process of judging the authenticity of users, and thus can be regarded as a classification problem. In order to improve the classification performance, multi-classifier information fusion is usually used to realize the automatic detection of spammers by utilizing the information from multiple classifiers. However, the existing fusion strategies do not reasonably take the uncertainty from the results of different classifiers (views) into account, and the relative importance and reliability of each classifier are not strictly distinguished.

Elucidating mechanisms of antitumor immunity mediated by live oncolytic vaccinia and heat-inactivated vaccinia.

Background: Viral-based immunotherapy can overcome resistance to immune checkpoint blockade (ICB) and fill the unmet needs of many patients with cancer. Oncolytic viruses (OVs) are defined as engineered or naturally occurring viruses that selectively replicate in and kill cancer cells. OVs also induce antitumor immunity.

Proteomic mechanisms for the regulation of growth, photosynthetic activity and nitrogen fixation in Nostoc sp. PCC 7120 exposed to three antibiotic contaminants.

This study investigated the influences of three frequently detected antibiotics in surface waters, ciprofloxacin, tetracycline and sulfamethoxazole, on the growth, photosynthetic activity, nitrogen-fixing capacity and proteomic expression profiles of Nostoc sp. PCC 7120, through a 15-day exposure test at environmentally relevant exposure doses of 50-200 ng/L. Cyanobacterial growth was stimulated by 100 ng/L and 200 ng/L of ciprofloxacin and sulfamethoxazole as well as 50-200 ng/L of tetracycline.

Nuclear Exosome Targeting Complex Core Factor Zcchc8 Regulates the Degradation of LINE1 RNA in Early Embryos and Embryonic Stem Cells.

The nuclear exosome targeting (NEXT) complex is responsible for specific nuclear RNA degradation in mammalian cells. However, its function in development remains unknown. Here, we find that the depletion of a central factor of the NEXT complex, Zcchc8, in mouse results in developmental defects, a shortened lifespan, and infertility.
