A plethora of preclinical evidences suggests that pharmacological targeting of epigenetic dysregulation is a potent strategy to combat human diseases. Nevertheless, the implementation of epidrugs in clinical practice is very scarce and mainly limited to haematological malignancies. In this review, we discuss cutting-edge strategies to foster the chemical design, the biological rationale and the clinical trial development of epidrugs. Read More

Regulatory T cells (Tregs) is one of the immunosuppressive subsets of CD4 T cells characterized by transcription factor forkhead box protein P3 (FOXP3) expression which are involved in tumor development and progression. Identification of the factors that influence Treg cell function is extremely important. Our current study aimed to evaluate the frequency of Treg cells, cytokine secretion and the expression of microRNAs (miRNAs) in pediatric acute lymphoblastic leukemia (ALL) patients. Read More

The clinical application of cytogenetic analysis and molecular-targeted drugs has dramatically improved the prognosis for many patients with hematologic malignancy, especially for those with chronic myeloid leukemia (CML) and acute promyelocytic leukemia (APL). Nevertheless, the treatment of hematologic malignancies is still faced with problems, such as disease recurrence and drug resistance, so further exploring the underlying molecular mechanism is urgent. With the discovery of different RNA species, the mechanism of RNA-RNA interaction has caught more and more attention. Read More

Background: The PI3K/Akt/mTOR (PI3K) signaling pathway has a crucial role in T-cell acute lymphoblastic leukemias (T-ALLs). Although loss-of-function of phosphatase and tensin homolog (PTEN) is a common event in pediatric T-ALLs, the exact role of this tumor suppressor in T-ALL development has yet to be defined.

Methods: Here, we report an optimized cytometric method for accurate proteomic profiling of T-ALL leukemic blasts at single-cell level. Read More

Monoclonal antibodies are high affinity multifunctional drugs that work by variable independent mechanisms to eliminate cancer cells. Over the last few decades, the field of antibody-drug conjugates, bispecific antibodies, chimeric antigen receptors (CAR) and cancer immunotherapy has emerged as the most promising area of basic and therapeutic investigations. With numerous successful human trials targeting immune checkpoint receptors and CAR-T cells in leukemia and melanoma at a breakthrough pace, it is highly exciting times for oncologic therapeutics derived from variations of antibody engineering.

Study Question: Do cumulative live birth rates (CLBRs) after one complete ART cycle differ between the three commonly used controlled ovarian stimulation (COS) protocols (GnRH antagonist, depot GnRHa (GnRH agonist) and long GnRHa) in normal responders undergoing IVF/ICSI?

Summary Answer: There were similar CLBRs between the GnRH antagonist, depot GnRHa and long GnRHa protocols.

What Is Known Already: There is no consensus on which COS protocol is the most optimal in women with normal ovarian response. The CLBR provides the final success rate after one complete ART cycle, including the fresh and all subsequent frozen-thawed embryo transfer (ET) cycles. Read More

Brain cancer is now the leading cause of cancer death in children and adolescents, surpassing leukemia. The heterogeneity and invasiveness of pediatric brain tumors have historically made them difficult to treat. Although surgical intervention and standard of care therapies such as radiation and chemotherapy have improved the outlook for those affected, results are often transient and lend themselves to tumor recurrence or resistance.

TcRαβ/CD19-cell depleted HLA-haploidentical hematopoietic stem cell transplantation (haplo-HSCT) represents a promising new platform for children affected by acute leukemia in need of an allograft and lacking a matched donor, disease recurrence being the main cause of treatment failure. The use of zoledronic acid to enhance TcRγδ+ lymphocyte function after TcRαβ/CD19-cell depleted haplo-HSCT was tested in an open-label, feasibility, proof-of-principle study.

In order to explore the prognostic value of CD2, CD4, and human leucocyte antigen-DR (HLA-DR) expression and Fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutation in leukemia cells in the bone marrow of patients with acute promyelocytic leukemia (APL), we retrospectively collected and analyzed the immunophenotype, molecular features and clinical characteristics of 219 newly diagnosed adult patients with APL in Henan Provincial People's Hospital from January 2010 to December 2019. It turned out that the relapse rates of patients with CD2, CD4, or HLA-DR expression and the early mortality rates of patients with CD2 expression, HLA-DR expression, or FLT3-ITD mutation were higher than those of their counterparts. Moreover, reduced overall survival was found for patients who showed CD2 expression, HLA-DR expression or FLT3-ITD mutation. Read More

With conventional anti-cancer drugs, including alkylating drugs, anti-metabolite drugs, topoisomerase inhibitors, and microtubule inhibitors, which have been available for half a century, the drug resistance often occurs due to decreased expression of target enzymes, with increased expression of drug export pumps.

Hypertension is a commonly reported comorbidity in patients diagnosed with chronic myeloid leukemia (CML), and its management represents a challenge in patients treated with 2nd- or 3rd-generation tyrosine kinase inhibitors (TKIs), considering their additional cardiovascular (CV) toxicity. The renin angiotensin system (RAS) contributes to hypertension genesis and plays an important role in atherosclerosis development, proliferation, and differentiation of myeloid hematopoietic cells. We analyzed a cohort of 192 patients with hypertension at CML diagnosis, who were treated with 2nd- or 3rd-generation TKIs, and evaluated the efficacy of RAS inhibitors (angiotensin-converting enzyme inhibitors (ACEi) and angiotensin-II receptor blockers (ARBs)) in the prevention of arterial occlusive events (AOEs), as compared with other drug classes.

The proviral integration site for Moloney murine leukemia virus (PIM) family of serine/threonine-specific kinases consist of three isoforms, that regulate proliferation, apoptosis, metabolism, invasion and metastasis of cancer cells. Among these, abnormally elevated kinase activity of PIM-1 contributes to the progression of gastric cancer and responsible for poor prognosis and low survival rate in gastric cancer patients. In the present study, we found that resveratrol, one of the representative chemopreventive and anticarcinogenic phytochemical, directly binds to PIM-1 and thereby inhibits its catalytic activity in human gastric cancer SNU-601 gastric cancer cells.

Selective and sensitive molecular probes for hydrogen peroxide (H 2 O 2 ), which plays diverse roles in oxidative stress and redox signalling, are urgently needed to investigate the physiological and pathological effects of H 2 O 2 . A lack of reliable tools for in vivo imaging has hampered the development of H 2 O 2 mediated therapeutics. By combining a specific tandem Payne/Dakin reaction with a chemiluminescent scaffold, H 2 O 2 -CL-510 was developed as a highly selective and sensitive probe for detection of H 2 O 2 both in vitro and in vivo .
