Because of legislative bans there are still no reports of human cloning. However eager public debate is currently running, concerning medical, legal, social and ethical aspects of human cloning. Arguments for and against human cloning are presented. An important argument against cloning is the danger of eugenic tendencies connected with cloning, which could lead to genetic discrimination.

Unlabelled: Once considered rare in eukaryotes, polycistronic mRNA expression has been identified in kinetoplastids and, more recently, green algae, red algae, and certain fungi. This study provides comprehensive evidence supporting the existence of polycistronic mRNA expression in the apicomplexan parasite . Leveraging long-read RNA-seq data from different parasite strains and using multiple long-read technologies, we demonstrate the existence of defined polycistronic transcripts containing 2-4 protein encoding genes, several validated with RT-PCR.

Targeting tumor angiogenesis with safe endogenous protein inhibitors is a promising therapeutic approach despite the plethora of the first line of emerging chemotherapeutic drugs. The extracellular matrix network in the blood vessel basement membrane and growth factors released from endothelial and tumor cells promote the neovascularization which supports the tumor growth. Contrastingly, small cleaved cryptic fragments of the C-terminal non collagenous domains of the same basement membrane display antiangiogenic effect.

Gene II Protein (Gp2/P2) is a nicking enzyme of the M13 bacteriophage that plays a role in the DNA replication of the viral genome. P2 recognizes a specific sequence at the f1 replication origin and nicks one of the strands and starts replication. This study was conducted to address the limitations of previous experiments, improve methodologies, and precisely determine the biochemical activity conditions of the P2 enzyme in vitro.

Background: An estimated 10-15% of all genetic diseases are attributable to variants in noncanonical splice sites, auxiliary splice sites and deep-intronic variants. Most of these unstudied variants are classified as variants of uncertain significance (VUS), which are not clinically actionable. This study investigated two novel splice-altering variants, NM_000390.

The Src homology 2 domain-containing inositol 5-phosphatase 1 (SHIP1) is a multidomain protein consisting of two protein-protein interaction domains, the Src homology 2 (SH2) domain, and the proline-rich region (PRR), as well as three phosphoinositide-binding domains, the pleckstrin homology-like (PHL) domain, the 5-phosphatase (5PPase) domain, and the C2 domain. SHIP1 is commonly known for its involvement in the regulation of the PI3K/AKT signaling pathway by dephosphorylation of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P) at the D5 position of the inositol ring. However, the functional role of each domain of SHIP1 for the regulation of its enzymatic activity is not well understood.
