The human ribosomes are the cellular machines that participate in protein synthesis, which is deeply affected during cancer transformation by different oncoproteins and is shown to provide cancer cell proliferation and therefore biomass. Cancer diseases are associated with an increase in ribosome biogenesis and mutation of ribosomal proteins. The ribosome represents an attractive anti-cancer therapy target and several strategies are used to identify specific drugs. Here we review the role of different drugs that may decrease ribosome biogenesis and cancer cell proliferation.
We have analyzed the distribution of allele frequencies at 12 Y-chromosomal short tandem repeats loci (DYS19, DYS385a, DYS385b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439) in the representative sample of Bosnian and Herzegovinians. A total of 100 unrelated male individuals (Caucasians) from different regions of Bosnia and Herzegovina have been sampled for the analysis. Samples were collected with a respect to the approximate proportional participation of three main ethnic groups in Bosnia and Herzegovina [Bosniacs-Muslim (35), Serbs (31), Croats (34)].
Leukemia represents the most prevalent malignancy in children, constituting 30% of childhood cancer cases, with acute lymphoblastic leukemia (ALL) being particularly heterogeneous. This paper explores the role of alternative splicing in leukemia, highlighting its significance in cancer development and progression. Aberrant splicing is often driven by mutations in splicing-factor genes, which can lead to the production of variant proteins that contribute to oncogenesis. The spliceosome, a complex of small nuclear RNAs and proteins, facilitates RNA splicing, a process critical for generating diverse mRNA and protein products from single genes. Mutations in splicing factors, such as U2AF1, SF3B1, SRSF2, ZRSR2, and HNRNPH1, are frequently observed across various hematological malignancies and are associated with poor prognosis and treatment resistance. This research underscores the necessity of understanding the mechanisms of RNA splicing dysregulation in order to develop targeted therapies to correct these aberrant processes, thereby improving outcomes for patients with leukemia and related disorders.
Systemic lupus erythematosus (SLE) is a disease associated with an impaired autoimmune response; the immune system attacks erroneously own tissues, which leads to inflammation, tissue damage and complement activation. The latter plays a pivotal role in SLE pathology, as complement level is suited as histological marker for disease diagnoses and management. Besides, environmentally factors have been highlighted and their significant contribution for individual genetic predisposition has been pointed out. Here complement factors, their activity and their ability to modify DNA with histone proteins are reviewed; known gene mutations involved in SLE, and new therapeutic approaches suggested for SLE are discussed and summarized, as well.
