A clinical predictive model for pre-transplantation colonization and relevance for clinical outcomes in patients receiving allogeneic hematopoietic stem cell transplantation.

The purpose of this study is to establish a clinical prediction model to discriminate patients at high risk of (KP) colonization before allogeneic hematopoietic stem cell transplantation (allo-HSCT) and evaluate the impact of KP colonization on clinical outcomes after allo-HSCT. We retrospectively collected data from 2,157 consecutive patients receiving allo-HSCT between January 2018 and March 2022. KP colonization was defined as a positive test for KP from a pharyngeal or anal swab before allo-HSCT.

Targeting Diverse Wounds and Scars: Recent Innovative Bio-design of Microneedle Patch for Comprehensive Management.

Wounds and the subsequent formation of scars constitute a unified and complex phased process. Effective treatment is crucial; however, the diverse therapeutic approaches for different wounds and scars, as well as varying treatment needs at different stages, present significant challenges in selecting appropriate interventions. Microneedle patch (MNP), as a novel minimally invasive transdermal drug delivery system, has the potential for integrated and programmed treatment of various diseases and has shown promising applications in different types of wounds and scars.

LINC02561 promotes metastasis in HCC via HIF1-α/NDRG1/UPF1 axis.

In the entire world, hepatocellular carcinoma (HCC) is one of the most frequent cancers that lead to death. Experiments on the function of long non-coding RNAs in the emergence of malignancies, including HCC, are ongoing. As a crucial RNA monitoring mechanism in eucaryotic cells, nonsense-mediated mRNA decay (NMD) can recognize and destroy mRNAs, which has an premature termination codons (PTC) in the open reading frame to prevent harmful buildup of truncated protein products in the cells.

Objective: To investigate the expression of WTAP gene in acute myeloid leukemia (AML) and its clinical significance.

Methods: 74 acute myeloid leukemia patients with non-M3 type and 19 normal donors were selected, and real-time quantitative polymerase chain reaction was used to detect the mRNA expression level of WTAP gene in their bone marrow cells. The relationship between the mRNA expression level of WTAP gene and the clinical characteristics was analyzed.

Allogeneic haematopoietic stem cell transplantation improves outcome of adults with relapsed/refractory Philadelphia chromosome-positive acute lymphoblastic leukemia entering remission following CD19 chimeric antigen receptor T cells.

Relapsed/refractory Philadelphia chromosome-positive acute lymphoblastic leukemia (r/r Ph+ ALL) has an extremely poor prognosis. Chimeric antigen receptor T-cell (CART) therapy has acquired unprecedented efficacy in B-cell malignancies, but its role in the long-term survival of r/r Ph+ ALL patients is unclear. We analyzed the effect of CART on 56 adults with r/r Ph+ ALL who accepted split doses of humanized CD19-targeted CART after lymphodepleting chemotherapy.

HMGB1 regulates SNAI1 during NSCLC metastasis, both directly, through transcriptional activation, and indirectly, in a RSF1-IT2-dependent manner.

High-mobility group protein B1 (HMGB1) has important functions in cancer cell proliferation and metastasis. However, the mechanisms of HMGB1 function in non-small-cell lung cancer (NSCLC) remain unclear. This study aimed to investigate the underlying mechanism of HMGB1-dependent tumor cell proliferation and NSCLC metastasis.

The role of high-mobility group protein box 1 in lung cancer.

High-mobility group protein box 1(HMGB1)is a ubiquitous highly conserved nuclear protein. Acting as a chromatin-binding factor, HMGB1 binds to DNA and plays an important role in stabilizing nucleosome formation, facilitating gene transcription, DNA repairing, inflammation, cell differentiation, and regulating the activity of steroid hormone receptors. Currently, HMGB1 is discovered to be related to development, progression, and targeted therapy of lung cancer, which makes it an attractive biomarker, and therapeutic target.

[Metabolomics of Chronic Myelogenous Leukemia Based on GC-MS].

Objective: To investigate the metabolism characteristics, to search for potential biomarkers associated with disease and to explore related metabolic pathways by analyzing the plasma metabolic profile of patients with chronic myelogenous leukemia (CML) through metabolomies.

Methods: Twenty-six newly diagnosed CML patients in the First Affilated Hospital of Soochow University from February 2015 to April 2015, 26 allogeneic hematopoietic stem cell donors as healthy controls and 26 patients treated with tyrosine kinase inhibitors (TKI) to obtain the best efficacy as post-treatment controls were enrolled in this study. All the metabolites of plasma were extracted by Gas Chromatography-Mass Spectrometer(GC-MS) to collect metabolic fingerprint.

MiR-106a-5p inhibits the cell migration and invasion of renal cell carcinoma through targeting PAK5.

MicroRNA-106a-5p (MiR-106a-5p), a small non-coding RNA, has been reported to be downregulated in astrocytoma, osteosarcoma and colorectal cancer. However, the expression levels and biological function in renal cell carcinoma (RCC) have not been studied yet. In this study, we found that the miR-106a-5p was significantly downregulated in RCC tissues and cell lines, and that overexpression of miR-106a-5p led to decreased cell metastasis ability in a xenograft model.

Egr-1 suppresses breast cancer cells proliferation by arresting cell cycle progression via down-regulating CyclinDs.

Egr-1 is an important nuclear transcription factor in the early growth response gene family (Egr family). Egr-1 was reportedly involved in the tumorigenesis of diverse tumors. However, there was a paucity of data regarding the role of Egr-1 in the breast cancer.

Rap2a serves as a potential prognostic indicator of renal cell carcinoma and promotes its migration and invasion through up-regulating p-Akt.

Rap2a, a member of the small GTPase superfamily, belongs to Ras superfamily, and its function in cancer progression is still poorly understood. Our previous study indicated that the ectopic expression of Rap2a enhanced the migration and invasion ability of lung cancer cells. However, its expression and molecular mechanism on renal cell carcinoma (RCC) have not been characterized.

Evaluation of the early response and mechanism of treatment of Parkinson's disease with L-dopa using F-fallypride micro-positron emission tomography scanning.

The aim of the present study was to investigate the use of F-fallypride micro-positron emission tomography (micro-PET) imaging in the evaluation of the early therapeutic efficacy of L-dopa in the treatment of Parkinson's disease (PD) and the underlying mechanism. F-fallypride was synthesized and its specific binding with dopamine (DA) receptors in normal mouse brain was studied. Following the establishment of a mouse model of PD, the animals were divided into normal control, PD model and L-dopa treatment groups.

Results: Tumour tissue samples from 60 patients with breast cancer were included.

Human CD133-positive hematopoietic progenitor cells initiate growth and metastasis of colorectal cancer cells.

The tumour-specific 'pre-metastatic niche' has emerged as a potential driving force for tumour metastasis and has been confirmed using mouse models of cancer metastasis. Vascular endothelial growth factor receptor-1(+) hematopoietic progenitor cells (HPCs) have been shown to play an important role in metastasis, forming a 'pre-metastatic niche' at designated sites for distant tumour progression. Here, CD133+ human umbilical hematopoietic progenitor cells (HUHPCs) were purified from human umbilical cord blood and expanded in vitro.

Association of the hsa-mir-499 (rs3746444) polymorphisms with gastric cancer risk in the Chinese population.

Background: Single-nucleotide polymorphisms (SNPs) in microRNAs (miRNA) have been shown to be related with susceptibility to several human cancers. We evaluated the associations of rs3746444 in pre-miRNA hsa-mir-499 with the risk of gastric cancer (GC) in the Chinese population.

Patients And Methods: The rs3746444 (A>G) SNPs were genotyped in 201 GC and 213 non-cancer subjects in a case-control study by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.
