… Hence another commonly used term for this discipline, ‘imaging genomics’. It is not uncommon to see the term ‘radiomics’ used interchangeably with radiogenomics in the literature, but the former better reflects the methodology of feature extraction from radiological images. …

Multiple myeloma hinders erythropoiesis and causes anaemia owing to high levels of CCL3 in the bone marrow microenvironment.

Anaemia is the most common complication of myeloma and is associated with worse clinical outcomes. Although marrow replacement with myeloma cells is widely considered a mechanistic rationale for anaemia, the exact process has not been fully understood. Our large cohort of 1363 myeloma patients had more than 50% of patients with moderate or severe anaemia at the time of diagnosis. Anaemia positively correlated with myeloma cell infiltration in the bone marrow (BM) and worse patient outcomes. The quantity and erythroid differentiation of HSPCs were affected by myeloma cell infiltration in the BM

Долгосрочная стабильность и производительность генных движителей на основе Cas9/Guide RNA в анофелиновых комарах.

Разрабатываются стратегии изменения численности населения с целью борьбы с распространением анофелиных комаров паразитов, вызывающих человеческую малярию. Эти подходы направлены на сокращение заболеваемости и заболеваемости за счет распространения доминирующих генов антипаратионного эффекта среди переносчиков инфекции. Для того чтобы штаммы могли оказывать эпидемиологическое воздействие, они должны в течение продолжительного периода времени сохранять свойства привода и подавления паразитов. Three Gene-drive штаммы, AcTP13 и AcTP43 в Anopheles coluszii и AgTP13 в Anopheles gambiae, с автономным

Therapeutic Targeting of Cancer Stem Cells in Human Glioblastoma by Manipulating the Renin-Angiotensin System.

Patients with glioblastoma (GB), a highly aggressive brain tumor, have a median survival of 14.6 months following neurosurgical resection and adjuvant chemoradiotherapy. Quiescent GB cancer stem cells (CSCs) invariably cause local recurrence. These GB CSCs can be identified by embryonic stem cell markers, express components of the renin-angiotensin system (RAS) and are associated with circulating CSCs. Despite the presence of circulating CSCs, GB patients rarely develop distant metastasis outside the central nervous system. This paper reviews the current literature on GB growth inhibition in r

Giant Cell Tumor of the Sacrum: A Narrative Review of Management Challenges and Modalities.

Background/Objectives: Sacral giant cell tumor of bone (GCTB) is a rare, mostly benign but locally aggressive neoplasm that carries significant diagnostic and treatment challenges due to its anatomic complexity, proximity to sacral nerve roots as well as the blood vessels, and potential impact on bowel, bladder, sexual, and lumbopelvic function and stability. This narrative review aimed to synthesize current evidence on the epidemiology, clinical presentation, diagnostic evaluation, classification, management strategies, outcomes, and surveillance of sacral GCTB. Methods: A focused literature

Hyaluronan (HA) interacting proteins RHAMM and hyaluronidase impact prostate cancer cell behavior and invadopodia formation in 3D HA-based hydrogels.

To study the individual functions of hyaluronan interacting proteins in prostate cancer (PCa) motility through connective tissues, we developed a novel three-dimensional (3D) hyaluronic acid (HA) hydrogel assay that provides a flexible, quantifiable, and physiologically relevant alternative to current methods. Invasion in this system reflects the prevalence of HA in connective tissues and its role in the promotion of cancer cell motility and tissue invasion, making the system ideal to study invasion through bone marrow or other HA-rich connective tissues. The bio-compatible cross-linking proce

Selective molecular inhibition of the HDAC6 ZnF-UBP binding domain impairs multiple myeloma cell function.

Multiple myeloma is a plasma cell malignancy with a poor prognosis despite the recent development of new therapeutic options. Histone deacetylase 6 (HDAC6) is overexpressed in multiple myeloma cells and may be involved in the acquisition of resistance to conventional anti-proteasome treatments. In addition to displaying a deacetylase catalytic activity, HDAC6 plays an essential role in the regulation of autophagy and cell death by recognizing ubiquitinated motifs from misfolded proteins through its C-terminal ZnF-UBP binding domain. These defective proteins are sent to the aggresome to facilit

Epigenetic profiling reveals key super-enhancer networks driving oncogenesis in HPV-positive HNSCC.

Human papillomavirus-positive (HPV+) head and neck squamous cell carcinoma (HNSCC) is a growing subset of cancer cases distinct from HPV-negative by fewer genetic mutations and prevalent epigenetic dysregulation. We mapped H3K27ac-marked super-enhancers (SEs) via ChIP-seq in HPV+ patient-derived xenografts (PDXs) and normal oropharyngeal mucosa, identifying tumor-specific SE domains (T-SEDs) enriched for transcription factors (TFs) including TP63, FOSL1, and JUND. These SE-associated TFs regulate key oncogenic pathways and are downregulated by BRD4 inhibition with JQ1, highlighting sensitivity

Artificial Intelligence and Machine Learning Technology Driven Modern Drug Discovery and Development.

The discovery and advances of medicines may be considered as the ultimate relevant translational science effort that adds to human invulnerability and happiness. But advancing a fresh medication is a quite convoluted, costly, and protracted operation, normally costing USD ~2.6 billion and consuming a mean time span of 12 years. Methods to cut back expenditure and hasten new drug discovery have prompted an arduous and compelling brainstorming exercise in the pharmaceutical industry. The engagement of Artificial Intelligence (AI), including the deep-learning (DL) component in particular, has bee

Landscape of small nucleic acid therapeutics: moving from the bench to the clinic as next-generation medicines.

The ability of small nucleic acids to modulate gene expression via a range of processes has been widely explored. Compared with conventional treatments, small nucleic acid therapeutics have the potential to achieve long-lasting or even curative effects via gene editing. As a result of recent technological advances, efficient small nucleic acid delivery for therapeutic and biomedical applications has been achieved, accelerating their clinical translation. Here, we review the increasing number of small nucleic acid therapeutic classes and the most common chemical modifications and delivery platf

Emerging Mechanisms and Treatment Progress on Liver Metastasis of Colorectal Cancer.

Colorectal cancer is currently the third largest malignant tumor in the world, with high new cases and high mortality. Metastasis is one of the most common causes of death of colorectal cancer, of which liver metastasis is the most fatal. Since the beginning of the Human Genome Project in 2001, people have gradually recognized the 3 billion base pairs that make up the human genome, of which only about 1.5% of the nucleic acid sequences are used for protein coding, including proto-oncogenes and tumor suppressor genes. A large number of differences in the expression of proto-oncogenes and tumor

Current Status of COVID-19 Therapies and Drug Repositioning Applications.

The rapid and global spread of a new human coronavirus (SARS-CoV-2) has produced an immediate urgency to discover promising targets for the treatment of COVID-19. Drug repositioning is an attractive approach that can facilitate the drug discovery process by repurposing existing pharmaceuticals to treat illnesses other than their primary indications. Here, we review current information concerning the global health issue of COVID-19 including promising approved drugs and ongoing clinical trials for prospective treatment options. In addition, we describe computational approaches to be used in dru

Solamargine induces autophagy-mediated apoptosis and enhances bortezomib activity in multiple myeloma.

Multiple myeloma (MM) is an incurable plasma cell malignancy with a poor survival rate. Conventional chemotherapeutic agent-induced adverse events, including toxicity, neuropathy or drug resistance, significantly decrease the patients' quality of life and can even lead to interruption of treatment. Therefore, novel therapeutic drugs and strategies are urgently needed to improve MM therapy and patient outcomes. Here, we show that solamargine (SM), a steroidal alkaloid glycoside isolated from a Chinese herb Solanum nigrum L., exhibits promising anti-MM activity. In particular, SM suppressed the

Osteolytic Lesion of the Maxilla in an Undiagnosed Multiple Myeloma Patient Identified Incidentally by Cone Beam Computed Tomography.

BACKGROUND Multiple myeloma is a hematological malignancy characterized by monoclonal plasma cell proliferation. Jaw lesions are found in nearly 35% of patients with symptomatic myeloma, and lesions occur in the mandible more often than in the maxilla. However, maxillary or mandibular lesions are rarely found as a primary manifestation of the disease. This report describes a case of a 65-year-old Palestinian woman with lytic lesions in the maxilla due to undiagnosed multiple myeloma identified incidentally on cone beam computed tomography (CBCT). CASE REPORT A 65-year-old Palestinian woman pre

Humanized Bone Model Identifies BMP6 as a Multifunctional Regulator in Myeloma Bone Disease.

Multiple myeloma (MM) is a plasma cell malignancy that disrupts bone homeostasis by suppressing osteogenesis and promoting osteoclast activity. While most therapeutic interventions to date have focused on targeting tumor cells and reducing osteolysis, we investigate whether osteoinductive strategies can restore bone formation and counteract disease progression. Using a human bone marrow-like scaffold model that enables direct in vivo evaluation of tumor-stroma interactions and human bone formation, we demonstrate that MM-derived mesenchymal stromal cells (MSCs) retain osteogenic potential but

PIWI-interacting RNAs (PiRNAs) as emerging biomarkers and therapeutic targets in biliary tract cancers: A comprehensive review.

Cancers affecting the biliary tract, such as gallbladder cancer and cholangiocarcinoma, make up a small percentage of adult gastrointestinal malignancies, but their incidence is on the rise. Due to the lack of dependable molecular biomarkers for diagnosis and prognosis, these cancers are often not detected until later stages and have limited treatment options. Piwi-interacting RNAs (piRNAs) are a type of small noncoding RNA that interacts with Piwi proteins and has been linked to various diseases, especially cancer. Manipulation of piRNA expression has the potential to serve as an important bi

G Protein-Coupled Receptor Signaling: Implications and Therapeutic Development Advances in Cancers.

G protein-coupled receptors (GPCRs) are the largest and most diverse class of membrane proteins, mediating cellular responses to a wide range of extracellular stimuli. GPCRs initiate complex intracellular signaling networks that regulate vital physiological functions and are associated with numerous diseases, including various types of cancer. Their conserved seven-transmembrane (7TM) structure enables these signaling networks by allowing interactions with multiple ligands and intracellular effectors. In several types of tumors, abnormal GPCR signaling promotes carcinogenesis by supporting imm

Old Drugs, New Battles: Unleashing Repurposed Drug Classes in Triple-Negative Breast Cancer Treatment.

Cancer remains a major global health challenge, with triple-negative breast cancer (TNBC) representing one of the most aggressive and difficult-to-treat subtypes, characterized by poor prognosis and limited therapeutic options. Current treatments, including chemotherapy, are hindered by high recurrence rates, drug resistance, and severe side effects, highlighting the urgent need for novel therapeutic strategies to address these challenges. Drug repurposing, which involves the application of existing FDA-approved (Food and administration) drugs for new oncological uses, offers a cost-effective
