Concise Review: Regulation of Self-Renewal in Normal and Malignant Hematopoietic Stem Cells by Krüppel-Like Factor 4.

Pluripotent and tissue-specific stem cells, such as blood-forming stem cells, are maintained through a balance of quiescence, self-renewal, and differentiation. Self-renewal is a specialized cell division that generates daughter cells with the same features as the parental stem cell. Although many factors are involved in the regulation of self-renewal, perhaps the most well-known factors are members of the Krüppel-like factor (KLF) family, especially KLF4, because of the landmark discovery that this protein is required to reprogram somatic cells into induced pluripotent stem cells. Because KLF

Cancer Neoaxonogenesis: Mechanisms and Factors Involved in the Recruitment of Peripheral Nerves by Cancer Tissue.

Peripheral nerves provide a direct connection between the brain and the tumor microenvironment. This connection allows the nervous system to influence processes associated with the development, progression, and metastasis of different tumor types. Therefore, tumor innervation by peripheral nerve fibers is currently emerging as a characteristic that contributes to multiple hallmarks of cancer. Several experimental studies have shown that cancer progression involves actively inducing the ingrowth of autonomic and sensory nerve fibers into tumor tissue. In this process, known as neoaxonogenesis,

Co-Encapsulation of Multiple Antineoplastic Agents in Liposomes by Exploring Microfluidics.

The inherent complexity of cancer proliferation and malignancy cannot be addressed by the conventional approach of relying on high doses of a single powerful anticancer agent, which is associated with poor efficacy, higher toxicity, and the development of drug resistance. Multiple drug therapy (MDT) rationally designed to target tumor heterogeneity, block alternative survival pathways, modulate the tumor microenvironment, and reduce toxicities would be a viable solution against cancer. Liposomes are the most suitable carrier for anticancer MDT due to their ability to encapsulate both hydrophil

Hematopoeitic Cell Transplantation and CAR T-Cell Therapy: Complements or Competitors?

Allogeneic hematopoietic cell transplantation (allo-HCT) and chimeric antigen receptor T cell (CAR T) therapy are the main modalities of adoptive cellular immunotherapy that have widely permeated the clinical space. The advent of both technologies revolutionized treatment of many hematologic malignancies, both offering the chance at sustained remissions for patients who would otherwise invariably succumb to their diseases. The understanding and exploitation of the nonspecific alloreactivity of allo-HCT and the graft-versus-tumor effect is contrasted by the genetically engineered precision of C

Unlocking the Heterogeneity in Acute Leukaemia: Dissection of Clonal Architecture and Metabolic Properties for Clinical Interventions.

Genetic studies of haematological cancers have pointed out the heterogeneity of leukaemia in its different subpopulations, with distinct mutations and characteristics, impacting the treatment response. Next-generation sequencing (NGS) and genome-wide analyses, as well as single-cell technologies, have offered unprecedented insights into the clonal heterogeneity within the same tumour. A key component of this heterogeneity that remains unexplored is the intracellular metabolome, a dynamic network that determines cell functions, signalling, epigenome regulation, immunity and inflammation.

Vision of Life's Code: Molecular Probe Nanoarchitectonics for Deep RNA/DNA Illumination.

Visualization of RNA and DNA provides a window of opportunity for the early detection of multiple diseases and approaches to manipulate them before any pathological processes occur. However, current imaging systems often fail to meet these demands due to the need for multiple RNA and DNA chemical probes, which increases experimental complexity, reduces awareness of false positives, and limits imaging accuracy in complex biosystems. In this work, we identify the key challenges associated with using multiple probes for RNA and DNA imaging and analyze the mechanisms and performance of existing im

Recombinant Oncolytic Viruses: Hexagonal Warriors in the Field of Solid Tumor Immunotherapy.

Boosting Immunity against Multiple Myeloma.

Despite the improvement of patient's outcome obtained by the current use of immunomodulatory drugs, proteasome inhibitors or anti-CD38 monoclonal antibodies, multiple myeloma (MM) remains an incurable disease. More recently, the testing in clinical trials of novel drugs such as anti-BCMA CAR-T cells, antibody-drug conjugates or bispecific antibodies broadened the possibility of improving patients' survival. However, thus far, these treatment strategies have not been able to steadily eliminate all malignant cells, and the aim has been to induce a long-term complete response with minimal residua

Personal Medicine and Bone Metastases: Biomarkers, Micro-RNAs and Bone Metastases.

Bone metastasis is a major cause of morbidity within solid tumours of the breast, prostate, lung and kidney. Metastasis to the skeleton is associated with a wide range of complications including bone fractures, spinal cord compression, hypercalcaemia and increased bone pain. Improved treatments for bone metastasis, such as the use of anti-bone resorptive bisphosphonate agents, within post-menopausal women have improved disease-free survival; however, these treatments are not without side effects. There is thus a need for biomarkers, which will predict the risk of developing the spread to bone
