Tumour Cell Size Control and Its Impact on Tumour Cell Function.

Cell size is an important component of cell morphological characteristics. It reflects the characteristics of the cell type, nutritional status, growth stage and physiological function. The cell size of cells of the same type tends to be homogeneous and stable. However, in tumour cells, mutations in cell cycle genes and cytoskeletal genes and overexpression of the corresponding signalling pathways often lead to large variations in tumour cell size. Tumour cells regulate cell size and growth and proliferation through multiple signalling pathways, such as PI3K/Akt/mTOR, Myc and Hippo pathways, w

Mesenchymal Stromal Cells in Neuroblastoma: Exploring Crosstalk and Therapeutic Implications.

Neuroblastoma (NB) is the second most common solid cancer in childhood, accounting for 15% of cancer-related deaths in children. In high-risk NB patients, the majority suffers from metastasis. Despite intensive multimodal treatment, long-term survival remains <40%. The bone marrow (BM) is among the most common sites of distant metastasis in patients with high-risk NB. In this environment, small populations of tumor cells can persist after treatment (minimal residual disease) and induce relapse. Therapy resistance of these residual tumor cells in BM remains a major obstacle for the cure of NB.

Bone sialoprotein: a multifunctional regulator of bone remodelling and tumour progression.

Bone sialoprotein (BSP) is a major non-collagenous protein of the bone extracellular matrix and an important regulator of bone formation and resorption. BSP is produced by bone cells and chondrocytes and present in the bone matrix, cells, dentin and cartilage. However, its aberrant expression in primary tumour tissues and the sera of cancer patients with metastases implicates BSP in tumour biology and progression. The Arg-Gly-Asp (RGD) motif of BSP may be crucial not only for the attachment of metastasising cells to the bone surface but also for tumour growth, survival and activity. This revie

Osteoid cell-derived chemokines drive bone-metastatic prostate cancer.

One of the greatest challenges in improving prostate cancer (PCa) survival is in designing new therapies to effectively target bone metastases. PCa regulation of the bone environment has been well characterized; however, bone-targeted therapies have little impact on patient survival, demonstrating a need for understanding the complexities of the tumor-bone environment. Many factors contribute to creating a favorable microenvironment for prostate tumors in bone, including cell signaling proteins produced by osteoid cells. Specifically, there has been extensive evidence from both past and recent

Targeting tumor-associated macrophages for cancer treatment.

Tumor-associated macrophages (TAMs) are abundant, nearly accounting for 30-50% of stromal cells in the tumor microenvironment. TAMs exhibit an immunosuppressive M2-like phenotype in advanced cancer, which plays a crucial role in tumor growth, invasion and migration, angiogenesis and immunosuppression. Consequently, the TAM-targeting therapies are particularly of significance in anti-cancer strategies. The application of TAMs as anti-cancer targets is expected to break through traditional tumor-associated therapies and achieves favorable clinical effect. However, the heterogeneity of TAMs makes

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

Molecular Mechanisms of Bone Metastasis: Which Targets Came from the Bench to the Bedside?

Bone metastases ultimately result from a complex interaction between cancer cells and bone microenvironment. However, prior to the colonization of the bone, cancer cells must succeed through a series of steps that will allow them to detach from the primary tumor, enter into circulation, recognize and adhere to specific endothelium, and overcome dormancy. We now know that as important as the metastatic cascade, tumor cells prime the secondary organ microenvironment prior to their arrival, reflecting the existence of specific metastasis-initiating cells in the primary tumor and circulating osteo

Emerging Therapeutics for the Treatment of Light Chain and Transthyretin Amyloidosis.

Cardiac amyloidosis is a restrictive cardiomyopathy that results from the deposition of misfolded light chain or transthyretin proteins, most commonly, in cardiac tissue.
