Evaluation of gecacitinib vs hydroxyurea in patients with intermediate-2 or high-risk myelofibrosis: final analysis results from a randomized phase 3 study.

To compare the efficacy and safety of gecacitinib (also known as jaktinib) with hydroxyurea (HU) in treating myelofibrosis (MF) patients. In this multicenter, randomized phase 3 trial (ZGJAK016), intermediate- or high-risk primarily JAK inhibitor naïve MF patients were assigned in a 2:1 ratio to receive either gecacitinib (100 mg twice a day, BID) or HU (500 mg BID). The primary endpoint was the proportion of patients with ≥35% reduction in spleen volume (SVR35) from baseline at week 24.

Efficacy, safety, and survival findings after long-term follow-up of ZGJAK002: A phase 2 study comparing jaktinib at 100 mg twice daily (BID) and 200 mg once daily (QD) in patients with myelofibrosis.

Jaktinib, a novel JAK and ACVR1 inhibitor, has exhibited promising results in treating patients with myelofibrosis (MF). ZGJAK002 is a Phase 2 trial aimed to assess the efficacy and safety of jaktinib 100 mg BID (N = 66) and 200 mg QD (N = 52) in JAK inhibitor-naive patients with intermediate- or high-risk MF. We herein present the long-term data with a median follow-up of 30.

We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications.

Interdigitating dendritic cell sarcoma of the spleen with hepatic failure after chemotherapy: A case report.

Rationale: Interdigitating dendritic cell sarcoma (IDCS) is an extremely rare disease originating from dendritic cells (DCs). There are few cases report interdigitating dendritic cell sarcoma of spleen along with their pathological characteristics and treatment.

Patient Concerns: Here we report a case of IDCS in 53-year-old female who presented spleen enlargement and thrombocytopenia.

Role of HMGB1 in regulation of STAT3 expression in CD4(+) T cells from patients with aGVHD after allogeneic hematopoietic stem cell transplantation.

Treg/Th17 balance plays a critical role in maintaining immune homeostasis of acute graft-versus-host disease (aGVHD) patients. STAT3 is an important factor involved in the instability of Treg and the promotion of Th17. HMGB1 is a cytokine mediator of inflammation and an important chromatin protein regulating gene transcription.

SUMOylation of insulin-like growth factor 1 receptor, promotes proliferation in acute myeloid leukemia.

Current valid treatments for acute myeloid leukemia (AML) include chemotherapy and hematopoietic stem cell transplantation, which are defective and limited respectively. The insulin-like growth factor 1 receptor (IGF-1R) is up-regulated in many solid tumors; therefore, it may be a target for tumor therapy. Interestingly, IGF-1R is modified by SUMOylation, a type of reversible post-translational modification.

MicroRNA-20b and ERK1/2 pathway independently regulate the expression of tissue factor in hematopoietic and trophoblastic differentiation of human embryonic stem cells.

Introduction: Tissue factor (TF) is expressed in various types of cells. TF expression is essential for many biological processes, such as blood coagulation and embryonic development, while its high expression in stem cells often leads to failure of transplantation. In this study, we used the human embryonic stem cell (hESC) culture system to understand the molecular mechanisms by which TF expression is regulated in hESC-derived hematopoietic and trophoblastic cells.

MiR-223 regulates human embryonic stem cell differentiation by targeting the IGF-1R/Akt signaling pathway.

Currently, there are difficulties associated with the culturing of pluripotent human embryonic stem cells (hESCs), and knowledge regarding their regulatory mechanisms is limited. MicroRNAs (miRNAs) regulate gene expression and have critical functions in stem cell self-renewal and differentiation. Moreover, fibroblast growth factor (FGF) and the insulin-like growth factor receptor (IGF-1R) are key activators of signaling in hESCs.

Allogeneic hematopoietic stem cell transplantation for patients with acute leukemia.

Objective: The purposes of this study were to assess the efficacy of allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia (AL) and analyze the factors affecting the prognosis of these patients.

Methods: The clinical and follow-up data of 93 AL patients (median age, 30 years) undergoing allogeneic HSCT in Xiangya Hospital over the past 12 years were collected, and the potential factors affecting the efficacy and prognosis of allogeneic HSCT patients were determined.

Results: Hematopoietic reconstitution was achieved in 90 patients.

Inactivation of PTEN increases ABCG2 expression and the side population through the PI3K/Akt pathway in adult acute leukemia.

Both the occurrence and recurrence of acute leukemia (AL) might suggest the presence of leukemia stem cells. Side population (SP) cells, exhibiting stem cell-like properties, express ABCG2 (breast cancer resistance protein [BCRP]). This study revealed that over-expression of ABCG2 in Jurkat and HL60 cells led to an increased SP fraction, up-regulated levels of phosphorylated-PI3K and phosphorylated-Akt, and enhanced drug resistance, all of which could be attenuated by treatment with either the PI3K inhibitor LY294002 or the mTOR inhibitor rapamycin.
