piR-823 tale as emerging cancer-hallmark molecular marker in different cancer types: a step-toward ncRNA-precision.

PIWI-interacting RNAs (piRNAs) have received a lot of attention for their functions in cancer research. This class of short non-coding RNAs (ncRNA) has roles in genomic stability, chromatin remodeling, messenger RNA (mRNA) integrity, and genome structure. We summarized the mechanisms underlying the biogenesis and regulatory molecular functions of piRNAs.

Tangled quest of post-COVID-19 infection-caused neuropathology and what 3P nano-bio-medicine can solve?

COVID-19-caused neurological problems are the important post-CoV-2 infection complications, which are recorded in ~ 40% of critically ill COVID-19 patients. Neurodegeneration (ND) is one of the most serious complications. It is necessary to understand its molecular mechanism(s), define research gaps to direct research to, hopefully, design new treatment modalities, for predictive diagnosis, patient stratification, targeted prevention, prognostic assessment, and personalized medical services for this type of complication.

Berberine ameliorates doxorubicin-induced cognitive impairment (chemobrain) in rats.

Aims: Cognitive decline is one of the most challenging issues for cancer survivors undergoing doxorubicin (DOX) based chemotherapy. Oxidative stress and inflammation primarily through tumor necrosis factor-alpha (TNF-α) are considered the key contributors to DOX-induced chemobrain. Berberine (BBR) has attracted much interest because of its anti-oxidative, anti-inflammatory and anti-apoptotic actions.
