Bone marrow stem-cell therapy for genetic and chronic liver diseases.

There are no permanent remedies for patients suffering from genetic liver diseases (GLDs) and liver cirrhosis (LC). In such cases, liver transplantation has resulted in improved quality of life, but it is not affordable by most patients. Therefore, a cost-effective, safe, and permanent cure for these diseases is desirable. Cell therapy seems an encouraging option for treatment of these liver diseases in the future. Animal experiments and clinical studies have demonstrated that, depending on the nature of the liver disease and the patient, autologous and/or allogeneic bone marrow (BM)-derived s

Gene therapy in large animal models of human cardiovascular genetic disease.

Several naturally occurring animal models for human genetic heart diseases offer an excellent opportunity to evaluate potential novel therapies, including gene therapy. Some of these diseases--especially those that result in a structural defect during development (e.g., patent ductus arteriosus, pulmonic stenosis)--would likely be difficult to treat with a therapeutic gene transfer approach. However, the ability to transduce a significant proportion of the myocardial cells should make the various forms of inherited cardiomyopathy amenable to a therapeutic gene transfer approach. Adeno-associat

Conceptualization vs reality in periodontal therapy: genetic testing and host modulation.

Emerging Therapies for Genetic Deafness: The Rise of Precision Gene Editing.

Hearing loss is a prevalent sensory disorder with profound social and health impacts. Although hearing aids and cochlear implants can significantly restore auditory perception, they do not address the underlying genetic causes. Inherited forms of hearing loss, often monogenic, are ideal candidates for gene therapy, particularly since over 150 genes have been linked to deafness. Advances in vector engineering and genome editing technologies now enable precise targeting of auditory cells within the inner ear. Technologies such as Clustered Regularly Interspaced Short Palindromic Repeats-Cas syst

Molecular and Genetic Markers for Malignant Melanoma: Implications for Prognosis and Therapy.

Despite therapeutic advancements, malignant melanoma remains a leading cause of skin cancer-related mortality, with incidence continuing to rise globally. Traditional prognostic tools offer important clinical guidance but fail to capture the biological heterogeneity of melanoma or reliably predict responses to emerging therapies. In this review, we summarize recent advances in prognostic and predictive molecular biomarkers reported over the past five years. We discuss immunohistochemical and tissue-based markers, circulating biomarkers, microRNAs, and gene expression profiles that enhance risk

Sarcoidosis in the Genomic Era: From Genetic Drivers to Tailored Therapies.

PURPOSE OF REVIEW: This review aims to synthesize existing literature on the genetics of sarcoidosis, including the genetic architectures associated with various clinical phenotypes, as well as current treatment options. It will also examine studies on phenotyping and endophenotyping sarcoidosis, along with offering new perspectives into pharmacogenetics and pharmacogenomics. The latter remains largely unexplored, which could potentially lead to new opportunities and further the goals of precision medicine. RECENT FINDINGS: Genetics and genomics have provided new insights into the study of sa

This abstract explores the recent advancements and potential applications of CRISPR-based therapies in addressing genetic components contributing to various neurodegenerative disorders. The review delves into the foundational

Genetics and epigenetics of primary Sjögren syndrome: implications for future therapies.

In primary Sjögren syndrome (pSS), chronic inflammation of exocrine glands results in tissue destruction and sicca symptoms, primarily of the mouth and eyes. Fatigue, arthralgia and myalgia are also common symptoms, whereas extraglandular manifestations that involve the respiratory, nervous and vascular systems occur in a subset of patients. The disease predominantly affects women, with an estimated female to male ratio of 14 to 1. The aetiology of pSS, however, remains incompletely understood, and effective treatment is lacking. Large-scale genetic and epigenetic investigations have revealed

The potential role for phage therapy for genetic modification of cutaneous diseases.

Antimicrobial resistance has become increasingly common across the globe, claiming more than 33,000 lives annually in Europe and 35,000 lives in the United States alone. The problem lies in trying to find potential solutions capable of tackling resistance and being able to fight infections that may resist various antimicrobials. Since Alexander Fleming's discovery in 1928, every antimicrobial synthesized in the past 70 years has developed at least one or more strains of resistant bacteria. One particular alternative to antimicrobials has brought hope to many in the scientific community: the ba

Genetically Modified T-Cell Therapy for Osteosarcoma: Into the Roaring 2020s.

T-cell immunotherapy may offer an approach to improve outcomes for patients with osteosarcoma who fail current therapies. In addition, it has the potential to reduce treatment-related complications for all patients. Generating tumor-specific T cells with conventional antigen-presenting cells ex vivo is time-consuming and often results in T-cell products with a low frequency of tumor-specific T cells. Furthermore, the generated T cells remain sensitive to the immunosuppressive tumor microenvironment. Genetic modification of T cells is one strategy to overcome these limitations. For example, T c

Genetic alterations of 9p24 in lymphomas and their impact for cancer (immuno-)therapy.

Chromosome 9 harbors several relevant oncogenes related to hematolymphoid malignancies and one specific region, 9p24, has come into the focus of attention in the last years as it contains recurrently mutant genes of therapeutic interest. The most prominent genes of this locus are programmed death ligands 1 and 2 (PDL1/PDL2), with the amplification of PDL1 being a hallmark of both classical Hodgkin and primary mediastinal B cell lymphoma, and Janus kinase 2 (JAK2), which is point-mutated in myeloproliferative neoplasms and other myeloid malignancies, and rearranged in PCM1-JAK2-positive myeloid

Restrictive Cardiomyopathy: Genetics, Pathogenesis, Clinical Manifestations, Diagnosis, and Therapy.

Restrictive cardiomyopathy (RCM) is characterized by nondilated left or right ventricle with diastolic dysfunction. The restrictive cardiomyopathies are a heterogenous group of myocardial diseases that vary according to pathogenesis, clinical presentation, diagnostic evaluation and criteria, treatment, and prognosis. In this review, an overview of RCMs will be presented followed by a detailed discussion on 3 major causes of RCM, for which tailored interventions are available: cardiac amyloidosis, cardiac sarcoidosis, and cardiac hemochromatosis. Each of these 3 RCMs is challenging to diagnose,

Genetic basis of cancer of the kidney: disease-specific approaches to therapy.

Studies during the past two decades have shown that kidney cancer is not a single disease; it is made up of a number of different types of cancer that occur in this organ. Clear cell renal carcinoma is characterized by mutation of the VHL gene. The VHL gene product forms a heterotrimeric complex with elongin C, elongin B, and Cul-2 to target hypoxia-inducible factors 1 and 2alpha for ubiquitin-mediated degradation. VHL-/- clear cell renal carcinoma overexpresses epidermal growth factor receptor and transforming growth factor alpha. Both hypoxia-inducible factor 1alpha and the epidermal growth

The FORKO mouse as a genetic model for exploring estrogen replacement therapy.

OBJECTIVE: To evaluate how chronically estrogen deficient female FORKO mice with genetic disruption of the FSH receptor respond to estrogen therapy. STUDY DESIGN: Subcutaneous estrogen agonist or antagonist therapy was initiated to study reproductive tissue response, adipose tissue mass and plasma lipid profiles. RESULTS: Within 36-48 hours of agonist administration, the classic measures of estrogenic activity were evident in the uterus and vagina. Older animals also responded to therapy during a 10-day period, indicating that estrogen receptor signaling systems are unaffected by aging. In t
