Introduction: The ever-evolving field of gene therapy promises several innovative treatments for cancer. Advances in genetic modification of tumor cells and micro environment have led to the development of more effective therapeutic strategies with fewer side effects.
Materials & Methods: The development of effective delivery system challenges, remains. Non-viral vectors are interesting due to their bio-safety and their ability to transfer different types of nucleic acids. Examples of these techniques are the use of oligonucleoides, liposomes, nanoparticles, inorganic material, and engineered stem cells.
Conclusion: In this review, we focus on recent advances in the intracellular delivery of DNA and siRNA to the cancer cells with emphasis on breast cancer.

Herein, fluorescent calcium carbonate nanoclusters encapsulated with methotrexate (Mtx) and surface functionalized with chitosan (25 nm) (@Calmat) have been developed for the imaging and treatment of triple-negative breast cancer (TNBC). These biocompatible, pH-sensitive nanoparticles demonstrate significant potential for targeted therapy and diagnostic applications. The efficacy of nanoparticles (NPs) was evaluated in MDA-MB-231 TNBC cell lines.

In this work, we evaluated the anticancer activity of compounds 1 (mononuclear) and 2 (dinuclear) copper(II) coordination compounds derived from the ligand 5-methylsalicylaldehyde 2-furoyl hydrazone (H2L) over MDA-MB-231 Triple-negative breast cancer (TNBC) cells, and compared their activities with that of a newly synthesized, protonated, dinuclear analogue of 2 (complex 3). Here, we report the synthesis of compound 3 and it has been characterized in the solid state (X-ray diffraction, FTIR) and in solution (EPR, UV-Vis, ESI) as well as its electrochemical profile. Complexes 1-3 impaired cell viability from 0.

Importance: Transportation insecurity and lack of social support are 2 understudied social determinants of health that contribute to excess morbidity, mortality, and acute health care utilization. However, whether and how these social determinants of health are associated with cancer screening has not been determined and has implications for preventive care.
Objective: To determine whether transportation insecurity or social support are associated with screening adherence for colorectal, breast, and cervical cancer.

Importance: Triple-negative breast cancer is an aggressive subtype with a high incidence in young patients, a high incidence in non-Hispanic Black women, and a high risk of progression to metastatic cancer, a devastating sequela with a 12- to 18-month life expectancy. Until recently, one strategy for treating early-stage triple-negative breast cancer was chemotherapy after surgery. However, it was not known whether the addition of immune therapy to postsurgery chemotherapy would be beneficial.
