Saikosaponin A (SSA), the primary active monomer derived from the Radix bupleuri, demonstrates a diverse array of pharmacological activities, including anti-inflammatory, antitumor, analgesic, anti-fibrotic, antidepressant, and immune-modulating properties. Despite its potential therapeutic impact on various human diseases, comprehensive studies exploring SSA's efficacy in these contexts remain limited. This review synthesizes the current research landscape regarding SSA's therapeutic applications across different diseases, highlighting critical insights to overcome existing limitations and clinical challenges.

The study of extrachromosomal DNA (ecDNA), an element existing beyond classical chromosomes, contributes to creating a more comprehensive map of the cancer genome. In hematological malignancies, research on ecDNA has lacked comprehensive investigation into its frequency, structure, function, and mechanisms of formation. We re-analyzed WGS data from 208 hematological cancer samples across 11 types, focusing on ecDNA characteristics.

Multiple myeloma (MM) is an incurable malignant plasma cell diseases, the incidence of which is increasing year by year. The application of immunomodulators drugs, proteasome inhibitors, anti-CD38 antibodies, CAR-T, and HSCT have significantly improved the prognosis of patients with MM, however new therapeutic tools need to be developed to improve the prognosis of patients with relapsed/refractory after conventional regimens treatment. Bispecific antibodies are a novel immunotherapeutic approach that generates immune synapses by binding to targets on malignant plasma cells and cytotoxic immune effector cells (T cells/natural killer cells), leading to T/NK cells activation and malignant plasma cell lysis.

Acute myeloid leukaemia (AML) is a prevalent haematological malignancy in which various immune and stromal cells in the bone marrow microenvironment have instrumental roles and substantially influence its progression. KIR2DL is a member of the immunoglobulin-like receptor family and a natural killer (NK) cell surface-specific receptor. However, its impact on immune infiltration regarding AML has not been addressed.

Salidroside is a natural product of phenols with a wide range of pharmacological functions, but whether it plays a role in regulating autophagy is unclear. We systematically investigated the regulatory effect and molecular mechanism of salidroside on autophagy through network pharmacology, which provided a theoretical basis for subsequent experimental research. First, the target genes of salidroside were obtained using the Chinese Medicine System Pharmacology Database and Analysis Platform, and the target genes were converted into standardized gene names using the Uniprot website.

Multiple myeloma (MM) is a hematologic neoplasm characterized by malignant proliferation of monoclonal plasma cells in the bone marrow. NK cells, a class of innate lymphocytes with potent natural killer activity, are capable of recognizing and destroying tumor cells and virally infected cells, and have attracted attention as a potential anticancer therapy. In patients with MM, NK cells are suppressed in number and function, resulting in reduced immune surveillance and clearance of myeloma cells.

Acute myeloid leukemia (AML) is a common hematological cancer. Cancer cells exchange information with the surrounding microenvironment, which can be transmitted by extracellular vesicles (EVs). In recent years, the genetic materials transported by EVs have attracted attention due to their important roles in different pathological processes.

Cancer-associated fibroblasts (CAF) are a key component of the tumor microenvironment, which can secrete a variety of cytokines, chemokines and growth factors, directly and indirectly support cancer cells, also alter the immune cellular environment by inhibiting the activity of immune effector cells and recruiting immunosuppressive cells, thereby allowing cancer cells to evade immune surveillance. CAF has been proven to be associated with the development, progression, and poor prognosis of solid tumors. However, the role of CAF in hematological malignancies is still unclear.

Background: Acute myeloid leukemia (AML) is one of the most common hematologic malignancies with a poor prognosis and high recurrence rate. The discovery of new predictive models and therapeutic agents plays a crucial role.

Methods: The differentially expressed gene that was explicitly highly expressed in The Cancer Genome Atlas (TCGA) and GSE9476 transcriptome databases were screened and included in the least absolute shrinkage and selection operator (LASSO) regression model to derive risk coefficients and build a risk score model.

Acute myeloid leukemia (AML) is a hematologic carcinoma that has seen a considerable improvement in patient prognosis because of genetic diagnostics and molecularly-targeted therapies. Nevertheless, recurrence and drug resistance remain significant obstacles to leukemia treatment. It is critical to investigate the underlying molecular mechanisms and find solutions.

Article Synopsis
  • Extramedullary plasma cell tumors (EMP) are a type of tumor with an unclear cause, categorized as primary or secondary based on their relation to multiple myeloma (MM).
  • Primary EMP tends to have a better prognosis with less invasive characteristics and is treated mainly with surgery and radiotherapy, while secondary EMP often indicates aggressive progression of MM and is associated with poorer outcomes, requiring more intensive treatments like chemotherapy and stem cell transplantation.
  • The paper reviews recent research developments in EMP, focusing on understanding its causes, genetic characteristics, and treatment options to assist clinical practices.
