Case report: TP53 c.848G>A germline mutation as a possible screening target at initial diagnosis for acute lymphoblastic leukemia.

Backgroud: Li-Fraumeni syndrome is a hereditary tumor syndrome characterized by an elevated risk of malignancy, particularly acute lymphoblastic leukemia (ALL), which can be caused by the heterozygous germline mutation. TP53 gene germline mutation is considered a potential risk factor and crucial prognostic parameter for acute leukemia development and diagnosis, but rarely occurs in adults, and its specific pathogenic significance in acute leukemia is unclear.

Case Presentation: We describes a case of a 45-year-old woman diagnosed with ALL.

Demethylating agents in combination with CD7-targeted CAR-T for the successful treatment of a case with mixed-phenotype acute leukemia relapsed after allogeneic hematopoietic stem cell transplantation: A Case Report.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has cured many patients with malignant hematologic diseases such as mixed phenotype acute leukemia (MPAL), while those relapsing after allo-HSCT still exhibit high mortality, poor prognosis, and no standard treatment modalities. It is necessary to explore more therapeutic modalities for patients with post-transplant relapse to obtain a better prognosis.

Case Presentation: In this case report, a young male with MPAL received allo-HSCT after reaching complete remission (CR) by induction chemotherapy.

The novel HLA-C*03:04:99 allele, identified by sanger dideoxy nucleotide sequencing in a Chinese individual.

HLA-C*03:04:99 differs from HLA-C*03:04:01:01 by one nucleotide in exon 5.

[Efficacy and Safety of PEG-rhG-CSF in HSC Mobilization in 71 Normal Healthy Donors for Allogeneic Hematopoietic Stem Cell Transplantation].

Objective: To retrospectively analyze the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in hematopoietic stem cell mobilization in 71 normal healthy donors for allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Methods: From March 2018 to July 2019, 71 patients received allo-HSCT in The General Hospital of Western Theater Command were enrolled in the study, a single dose of PEG-rhG-CSF was injected subcutaneously at 12 mg to all the stem cell donors. After injection for 4 days, CD34 cell number were detected, stem cells were collected on day 4 or 5 according to the CD34 cell number.

[Retracted] The inhibitory effect of MEG3/miR-214/AIFM2 axis on the growth of T-cell lymphoblastic lymphoma.

Following the publication of this paper, it was drawn to the authors' attention by an interested reader that a row of the tumour images featured in Fig. 8A of the above paper were strikingly similar to those featured in Fig. 6A of an article appearing in Oncology Reports that had been published by a different research group at a different institution [Zhang L, Liang X and Li Y: Long non‑coding RNA MEG3 inhibits cell growth of gliomas by targeting miR‑93 and inactivating PI3K/AKT pathway.

MEG3 affects the progression and chemoresistance of T-cell lymphoblastic lymphoma by suppressing epithelial-mesenchymal transition via the PI3K/mTOR pathway.

Long noncoding RNAs (lncRNA) are emerging as integral functional and regulatory components in the development of different diseases including cancer. Maternally expressed gene 3 (MEG3), is a lncRNA, that has a depressed expression in multiple tumor types, including T-cell lymphoblastic lymphoma (T-LBL). However, the molecular mechanisms that regulate the tumorigenic functions of MEG3 in T-LBL remain largely unknown.

PD-1 blockade potentially enhances adoptive cytotoxic T cell potency in a human acute myeloid leukaemia animal model.

Objectives: Acute myeloid leukaemia (AML) is a malignant haematological disease that remains difficult to cure. Cytotoxic T cell (CTL) adoptive infusion therapy may be conducive to tumour remission by boosting physical immunity. Furthermore, programmed death receptor-1 (PD-1) blockade immunotherapy has shown tremendous success in many cancer therapies.

Cytotoxic T lymphocytes promote cytarabine-induced acute myeloid leukemia cell apoptosis via inhibiting Bcl-2 expression.

Acute myeloid leukemia (AML) remains difficult to cure due to its drug tolerance and refractoriness. Immunotherapy is a growing area of cancer research, which has been applied for the treatment of numerous types of cancer, including leukemia. The present study generated AML cell-specific cytotoxic T lymphocytes (CTLs) and investigated the effect of combining CTL treatment with one of the most commonly used drugs for the treatment of hematological malignancies, cytarabine, on AML cell apoptosis.

The inhibitory effect of MEG3/miR-214/AIFM2 axis on the growth of T-cell lymphoblastic lymphoma.

T-cell lymphoblastic lymphoma (T-LBL) is an aggressive malignancy with poor prognosis and high recurrence rate. Long non-coding RNA (lncRNA)-MEG3 is an important tumor suppressor in various cancers. The present study investigated the potential role of maternally expressed gene 3 (MEG3) in the progression of T-LBL.

Enhanced antitumor effect of combining chemotherapy with Epstein-Barr virus (EBV)-specific cytotoxic T lymphocytes in mice with EBV-related non-Hodgkin's lymphoma.

Epstein-Barr virus (EBV)-related non-Hodgkin's lymphoma (NHL) represents a major problem in hematological clinical studies due to its drug tolerance and refractoriness. EBV infection is a key factor driving the process of tumor growth. Immune therapy is an important biotherapeutic method of treating cancer, which is attracting increasing attention.
