Hepatocellular carcinoma stem cells: the current state of small molecule-based inhibitors.

Hepatocellular carcinoma (HCC) is the most common type of liver cancer, accounting for over 90% of all cases. Patients with advanced-stage HCC are referred to systemic treatment. Although some advances in HCC therapy have been made in recent years, the prognosis for patients remains poor due to drug resistance, tumor relapse, and metastasis, implying that overall survival remains a challenge. Many studies have shown that tumor-initiating stem cells, also known as cancer stem cells (CSCs), play essential roles in tumorigenesis, metastasis, and treatment resistance in HCC and that future cancer

Unraveling the mechanisms of bone diseases: targeting dendritic cells in osteoimmunology for internal homeostasis balance.

Bone repair and regeneration is a complex spatiotemporal process recruiting a variety of cell types, which need to precisely mediated for effective healing post-damage. The concept of osteoimmunology emphasizes the extensive and intricate crosstalk between the bone and the immune system. Despite the significant advancements in understanding osteoimmunology, the precise role of dendritic cells (DCs) in this field remains under investigation. As key antigen-presenting cells, DCs are critical in orchestrating adaptive immune responses and maintaining tissue homeostasis. Recent researches have fur

Exosome-mediated repair of spinal cord injury: a promising therapeutic strategy.

Spinal cord injury (SCI) is a catastrophic injury to the central nervous system (CNS) that can lead to sensory and motor dysfunction, which seriously affects patients' quality of life and imposes a major economic burden on society. The pathological process of SCI is divided into primary and secondary injury, and secondary injury is a cascade of amplified responses triggered by the primary injury. Due to the complexity of the pathological mechanisms of SCI, there is no clear and effective treatment strategy in clinical practice. Exosomes, which are extracellular vesicles of endoplasmic origin w

Cancer is a complex illness that presents significant challenges in its understanding and treatment. The classic definition, "a group of diseases characterized by the uncontrolled growth and spread of abnormal cells in the body," fails to convey the intricate interaction between the many entities involved in cancer. Recent advancements in the field of cancer research have shed light on the role played by individual cancer cells and the tumor microenvironment as a whole in tumor development and progression. This breakthrough enables the utilization of the tumor and its components as biological

Multiple Myeloma Cell-Derived Exosomes: Implications on Tumorigenesis, Diagnosis, Prognosis and Therapeutic Strategies.

Multiple myeloma (MM) is a hematological disease that is still not curable. The bone marrow milieu, with cellular and non-cellular elements, participate in the creation of a pro-tumoral environment enhancing growth and survival of MM plasma cells. Exosomes are vesicles oscillating in dimension between 50 nm and 100 nm in size that can be released by various cells and contribute to the pathogenesis and progression of MM. Exosomes enclose proteins, cytokines, lipids, microRNAs, long noncoding RNAs, and circular RNAs able to regulate interactions between MM plasma cells and adjacent cells. Throug

Targeting cancer stem cells with CAR-based immunotherapy: biology, evidence, and future directions.

Cancer stem cells (CSCs) are pivotal in tumor initiation, progression, and relapse, underscoring the need for targeted therapies to achieve lasting responses. This review delves into CSC biology, highlighting their tumor-initiating potential demonstrated through limiting dilution assays and their role in resistance to therapies. Although successful CAR therapies, such as anti-CD19 CAR T-cells, can induce complete responses without directly targeting CSCs, CAR strategies focusing on CSCs may offer promising avenues to prevent recurrence. We assess CAR therapies targeting CSC-specific antigens,

The Bone Marrow Microenvironment Mechanisms in Acute Myeloid Leukemia.

Bone marrow (BM) is a highly complex tissue that provides important regulatory signals to orchestrate hematopoiesis. Resident and transient cells occupy and interact with some well characterized niches to produce molecular and cellular mechanisms that interfere with differentiation, migration, survival, and proliferation in this microenvironment. The acute myeloid leukemia (AML), the most common and severe hematological neoplasm in adults, arises and develop in the BM. The osteoblastic, vascular, and reticular niches provide surface co-receptors, soluble factors, cytokines, and chemokines that

Review on Bortezomib Resistance in Multiple Myeloma and Potential Role of Emerging Technologies.

Multiple myeloma is a hematological cancer type. For its treatment, Bortezomib has been widely used. However, drug resistance to this effective chemotherapeutic has been developed for various reasons. 2D cell cultures and animal models have failed to understand the MM disease and Bortezomib resistance. It is therefore essential to utilize new technologies to reveal a complete molecular profile of the disease. In this review, we in-depth examined the possible molecular mechanisms that cause Bortezomib resistance and specifically addressed MM and Bortezomib resistance. Moreover, we also included

CCN proteins in the musculoskeletal system: current understanding and challenges in physiology and pathology.

The acronym for the CCN family was recently revised to represent "cellular communication network". These six, small, cysteine-enriched and evolutionarily conserved proteins are secreted matricellular proteins, that convey and modulate intercellular communication by interacting with structural proteins, signalling factors and cell surface receptors. Their role in the development and physiology of musculoskeletal system, constituted by connective tissues where cells are interspersed in the cellular matrix, has been broadly studied. Previous research has highlighted a crucial balance of CCN prote

Cancer metastasis to the bone: Mechanisms and animal models (Review).

The majority of cancer-related deaths result from tumor metastasis, with bone metastasis occurring in almost all types of malignant tumors. Understanding the mechanism by which tumors metastasize to bone is critical for the identification of novel therapeutic targets. A large amount of research has been carried out using animal models, and these models have been crucial in advancing the fundamental understanding of cancer. However, current models are limited; although they can mimic specific stages of the metastatic process, they are not able to replicate the entire process from tumorigenesis
