Targeted delivery of DAPT using dual antibody functionalized solid lipid nanoparticles for enhanced anti-tumour activity against triple negative breast cancer.

Triple-negative breast cancer (TNBC) is a subtype known for its aggressive nature, high rates of recurrence, and treatment resistance, largely attributed to the presence of breast cancer stem cells (BCSCs). Traditional therapies often struggle to eliminate BCSCs, which contributes to tumor recurrence. One promising strategy for addressing this challenge is targeting the Notch signaling pathway, which plays a critical role in the self-renewal and maintenance of BCSCs.

An Update on Emergent Nano-Therapeutic Strategies against Pediatric Brain Tumors.

Pediatric brain tumors are the major cause of pediatric cancer mortality. They comprise a diverse group of tumors with different developmental origins, genetic profiles, therapeutic options, and outcomes. Despite many technological advancements, the treatment of pediatric brain cancers has remained a challenge.

Tumor microenvironment and nanotherapeutics: intruding the tumor fort.

Over recent years, advancements in nanomedicine have allowed new approaches to diagnose and treat tumors. Nano drug delivery systems exploit the enhanced permeability and retention (EPR) effect and enter the tumor tissue's interstitial space. However, tumor barriers play a crucial role, and cause inefficient EPR or the homing effect.

MicroRNA Signatures in Blood or Bone Marrow Distinguish Subtypes of Pediatric Acute Lymphoblastic Leukemia.

OncomiRs are microRNAs that are associated with early onset of specific cancers. To identify microRNAs involved in pediatric acute lymphoblastic leukemia (ALL) subtypes T-ALL and B-ALL, peripheral blood and bone marrow samples were independently subjected to microarray analysis using two different high-fidelity array platforms. The unique and common gene signatures from both arrays were validated by TaqMan individual assays in 100 pediatric ALL samples.

Cadmium toxicity-induced proline accumulation is coupled to iron depletion.

Investigations were conducted to elucidate the key factor behind Cd-toxicity-induced proline accumulation in Indian mustard (Brassica juncea) by raising seedlings, independently in distilled water (DW) and mineral growth medium (MGM) in the presence of 0-500 μM CdCl. Invariably, Cd-induced toxicity, measured in terms of growth, was significantly more prominent in seedlings raised in DW than those raised in MGM. Cd brought about a significant reduction in growth and photosystem II activity with a concomitant increase in proline levels, in a concentration-dependent manner.
