Comparative study of the brain of developed and underdeveloped neonatal rodents of the Muridae family

Morphological studies have been made of the neocortical and archicortical structures in the spiny mouse Acomys cahirinus, the only maturely born species from the family Muridae. The data obtained reveal highly developed hippocampus as compared to the neocortex in this mouse, in contrast to relationships found in other mice and rats.

SPLUNC1 Regulates Cell Progression and Apoptosis through the miR-141-PTEN/p27 Pathway,but Is Hindered by LMP1

Little is known about the role of the host defensive protein short palate, lung and nasal epithelium clone 1 (SPLUNC1) in the carcinogenesis of nasopharyngeal carcinoma (NPC). Here we report that SPLUNC1 plays a role at a very early stage of NPC carcinogenesis. SPLUNC1 regulates NPC cell proliferation, differentiation and apoptosis through miR-141, which in turn regulates PTEN and p27 expression. This signaling axis is negatively regulated by the EBV-coded gene LMP1. Therefore we propose that SPLUNC1 suppresses NPC tumor formation and its inhibition by LMP1 provides a route for NPC tumorigenesis.     

Optimal protocols of hematopoietic stem cell expansion in vitro

Hematopoietic stem cells (HSCs) effectively and continuously replenish the full range of blood-cell populations. Bone-marrow and umbilical-cord blood stem-cell transplantation (SCT) restore hematopoiesis when used in various hematological and oncohematological disorders in adults and children. However, wider clinical application of effective SCT-based approaches is limited by the low number of primitive HSCs in the available biospecimens. Development of effective protocols of HSC expansion in vitro is therefore necessary. In this review, the notion of bone marrow hematopoiesis is discussed as a complex cellular system and a comparative analysis of various methods for HSC expansion in vitro is provided. The review is illustrated by our own data supporting application of various feeder-cell types for human HSC expansion in vitro.     

Dzeren from the cavicorn fauna of the Nalaikha locality

A small cavicorn, Gazella (Procapra) gutturosa Gmelin, 1760, is described from the Nalaikha locality (Mongolia) and assigned to the Upper Villafranchian based on the age of the Nalaikha mammal fauna.
