Circular RNAs as Key Regulators in Cancer Hallmarks: New Progress and Therapeutic Opportunities.

Circular RNAs (circRNAs) have emerged as critical regulators in cancer biology, contributing to various cancer hallmarks, including cell proliferation, apoptosis, metastasis, and drug resistance. Defined by their covalently closed loop structure, circRNAs possess unique characteristics like high stability, abundance, and tissue-specific expression. These non-coding RNAs function through mechanisms such as miRNA sponging, interactions with RNA-binding proteins (RBPs), and modulating transcription and splicing.

Cytogenomic characterization of murine osteosarcoma cell line SEWA.

Introduction: The SEWA cell line, which is derived from a virus induced murine osteosarcoma (OS) ascites was established in the 1980s from a serially transplanted male derived tumor that first published in 1961. It has been applied in about 50 studies but was never genetically characterized in detail; this study fills that gap.

Methods: The SEWA cell line was analyzed for its chromosomal constitution using molecular cytogenetic approaches.

Cytogenomic Characterization of Murine Neuroblastoma Cell Line Neuro-2a and Its Two Derivatives Neuro-2a TR-Alpha and Neuro-2a TR-Beta.

Background: The Neuro-2a cell line, derived from a murine neuroblastoma (NB), was established as early as 1969 and originates from a transplantable tumor that arose spontaneously in an A/Jax male mouse in 1940. Since then, it has been applied in over 10,000 studies and is used by the World Organization for Animal Health for the routine diagnosis of rabies. Surprisingly, however, Neuro-2a has never been genetically characterized in detail; this study fills that gap.

Complex chromosomal rearrangements in female carriers experiencing recurrent pregnancy loss or poor obstetric history and literature review.

Purpose: Complex chromosomal rearrangements (CCRs) often remain unidentified as they are rarely observed in the general population. Females with CCRs are generally recognized on the identification of an affected child with multiple congenital anomalies (MCA) or having a history of repeated pregnancy loss/bad obstetric history (RPL/BOH). In contrast, males with CCRs are diagnosed primarily due to infertility.
