AI Article Synopsis

  • Despite extensive research over the past ten years, there is no standard method for imaging apoptosis in cancer patients, and proposed tracers have yet to gain FDA approval.
  • Radiolabeled annexin V is one of the few radiotracers that has been used in Phase II trials and is still in development.
  • This review will discuss the mechanisms of apoptosis, highlight recent in vivo imaging data, and aim to enhance understanding of cell death pathways to facilitate the development of radiopharmaceuticals that can effectively image apoptosis for cancer treatment.

Article Abstract

Despite over a decade of intense investigation there is still no routine method for the clinical imaging of apoptosis in oncologic patients. There have been multiple tracers proposed but none as of yet has received FDA approval. Radiolabeled annexin V is one of the few radiotracers that has been widely used in Phase II trials and is still under development. In this review we will first detail the general mechanisms involved with apoptosis and other common forms of cell death. Next we will outline the latest in vivo imaging data in animal models and humans including that obtained with radiolabeled annexin V. It is hoped that improved understanding of the complex biochemical pathways involved with cell death will lead to at least several radiopharmaceuticals with the ability to image apoptosis as part of improving the care and treatment of patients suffering from cancer.

Motor symptom laterality is an important clinical feature of PD that not only manifests as lateral limb dysfunction but also affects the nonmotor symptoms and the prognosis in PD patients. Previous studies suggested that the compensatory mechanisms in the dominant hemisphere of the brain may be an underlying explanation. The corpus callosum (CC) is the largest fiber connecting the two hemispheres of the brain.

Introduction: Hepatocellular carcinoma (HCC), the third leading cancer mortality worldwide, shows rising incidence. The mitochondria in HCC cells are prone to damage from metabolic stress and oxidative stress, necessitating heightened mitophagy for mitochondrial homeostasis and cell survival. Thus, mitophagy inhibition is a promising HCC therapy.

FA-PEG Modified ZIF(Mn) Nanoparticles Loaded with Baicalin for Imaging-Guided Treatment of Melanoma in Mice.

Background: Melanoma is an aggressive skin tumor with limited therapeutic options due to rapid proliferation, early metastasis, and poor prognosis. Baicalin (BA), a natural flavonoid, shows promise in inducing ferroptosis and apoptosis but faces challenges of poor solubility and bioavailability. To address these issues, we developed a multifunctional drug delivery system: manganese-doped ZIF-8 nanoparticles (ZIF(Mn)) loaded with BA and modified with folic acid (FA) and polyethylene glycol (PEG).

The locus coeruleus (LC) produces most of the brain's noradrenaline (NA). Among its many roles, NA is often said to be neuroprotective and important for brain upkeep. For this reason, loss of LC integrity is thought to impact brain volume and microstructure as well as plasticity broadly.

The effect of digestion on nanocarriers will affect the release and pharmacological effects of bioactive compounds in delivery systems. The digestion of cellulose is limited to gut microbiota, which offers a new research strategy for targeted delivery of bioactive compounds. Herein, positively charged cellulose-like chitosan/polyvinylpyrrolidone nanofiber was prepared to improve the residence time, colon target and gut microbiota regulation activity of quercetin decorated selenium nanoparticles (QUE@SeNPs/CS/PVPNFs).
