CEACAM1 participation in breast cancer progression
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

TGFβ secreted by tumor cells and/or tumor infiltrating stromal cells is a key mediator of tumor growth and immune suppression at the tumor site. Nonetheless, clinical trials in cancer patients targeting the TGFβ pathway exhibited at best a modest ...

The Long and Short of siRNAs [PDF]
A recent work identifies a distinct class of siRNAs derived from transgenes and endogenous retroelements in plants (Hamilton et al., 2002). This class has slower electrophoretic mobility than previously characterized siRNAs and may play an important role in transgene-induced systemic silencing and in methylation of endogenous retroelement DNA.

We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

RNA modifications in mammals: from basic research to biotechnological application [PDF]
RNA, a crucial molecule in protein synthesis and gene expression regulation, plays an essential role in organisms. RNA modifications, acting as epigenetic marks, subtly adjust the structure, stability, and function of RNA, thereby regulating gene ...

Rekindling RNAi Therapy: Materials Design Requirements for In Vivo siRNA Delivery
With the recent FDA approval of the first siRNA‐derived therapeutic, RNA interference (RNAi)‐mediated gene therapy is undergoing a transition from research to the clinical space.

In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Small RNA pathways in mammalian oocytes
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Epigenetic regulation as a promising tool for treatment of atherosclerosis
Atherosclerosis is one of the leading causes of death from cardiovascular disease (CVD) that primarily involves mid size and large arteries. Atherosclerosis is associated with disruption of lipid metabolism and chronic inflammatory processes.
