Abstract
Gene transfection, defined by the delivery of nucleic acids into cellular compartments, stands as a crucial procedure in gene therapy. While branched polyethylenimine (PEI) is widely regarded as the "gold standard" for nonviral vectors, its cationic nature presents several issues, including nonspecific protein adsorption and notable cytotoxicity. Additionally, it often fails to achieve high transfection efficiency, particularly with hard-to-transfect cell types. To overcome these challenges associated with PEI as a vector for plasmid DNA (pDNA), the photothermal agent indocyanine green (ICG) is integrated with PEI and pDNA to form the PEI/ICG/pDNA (PI/pDNA) complex for more efficient and safer gene transfection. The negatively charged ICG serves a dual purpose: neutralizing PEI's excessive positive charges to reduce cytotoxicity and, under near-infrared irradiation, inducing local heating that enhances cell membrane permeability, thus facilitating the uptake of PI/pDNA complexes to boost transfection efficiency. Using pDNA encoding vascular endothelial growth factor as a model, our system shows enhanced transfection efficiency in vitro for hard-to-transfect endothelial cells, leading to improved cell proliferation and migration. Furthermore, in vivo studies reveal the therapeutic potential of this system in accelerating the healing of infected wounds by promoting angiogenesis and reducing inflammation. This approach offers a straightforward and effective method for gene transfection, showing potentials for tissue engineering and cell-based therapies.

Abstract
Gene therapy is one of the most advanced therapies in current medicine. In particular, interference RNA-based therapy by small interfering RNA (siRNA) has gained attention in recent years as it is a highly versatile, selective and specific therapy. In dermatological conditions, topical delivery of siRNA offers numerous therapeutic advantages, mainly by inhibiting the expression of target transcripts directly in the skin. However, crossing the stratum corneum and overcoming intracellular barriers is an inherent challenge. Substantial efforts by scientists have moved towards the use of multimodal and multifunctional nanoparticles to overcome these barriers and achieve greater bioavailability in their site of action, the cytoplasm. In this review the most innovative strategies based on nanoparticle and physical methods are presented, as well as the design principles and the main factors that contribute to the performance of these systems. This review also highlights the synergistic contributions of medicine, nanotechnology, and molecular biology to advancing translational research into siRNA-based therapeutics for skin diseases.

Abstract
Gene therapy (GT) and photothermal therapy (PTT) have emerged as promising alternatives to chemotherapy and radiotherapy for cancer treatment, offering noninvasiveness and reduced side effects. However, their efficacy as standalone treatments is limited. GT exhibits slow response rates, while PTT is confined to local tumor ablation. The convergence of GT and PTT, known as GT-PTT, facilitated by photothermal gene nanocarriers, has attracted considerable attention across various disciplines. In this integrated approach, GT reciprocates PTT by sensitizing cellular response to heat, while PTT benefits GT by improving gene translocation, unpacking, and expression. Consequently, this integration presents a unique opportunity for cancer therapy with rapid response and improved effectiveness. Extensive efforts over the past few years have been dedicated to the development of GT-PTT, resulting in notable achievements and rapid progress from the laboratory to potential clinical applications. This comprehensive review outlines recent advances in GT-PTT, including synergistic mechanisms, material systems, imaging-guided therapy, and anticancer applications. It also explores the challenges and future prospects in this nascent field. By presenting innovative ideas and insights into the implementation of GT-PTT for enhanced cancer therapy, this review aims to inspire further progress in this promising area of research.

Abstract
Many studies have been conducted on the transduction efficiency of recombinant adeno-associated virus (rAAV) depending on the serotype and genome structure, such as single-stranded (ss) and self-complementary (sc). To understand the variation in therapeutic efficacy, we focused on investigating subcellular distribution of viral genome depending on rAAV genome structure. It is critical to ascertain the location of the virus within the host cell after the entry because a larger amount of the viral genome placed in the nucleus facilitates viral genome replication by utilizing the host cell's system, thereby enhancing the therapeutic outcome. In this sense, tracking the location of the virus within the host cell's organelles can inform a new strategy to improve therapeutic efficacy. Therefore, we attempted to stain only the viral genome with APEX2 and DAB chemicals specifically, and the distribution of the viral genome was examined by transmission electron microscopy (TEM). Consequently, when the two types of rAAV were transduced for 6 h, scAAV2 tended to be more located in the lysosome and nucleus compared to ssAAV2.

Abstract
In this work, a series of mesoporous carbon nanocapsules (mCNS) of size below 10 nm have been prepared from Azadirachta indica seeds with a very easy and cost-effective approach. These nanocapsules can emit red and green light and are effective for cell imaging. Further, these carbon nanocapsules are biocompatible toward the normal healthy cells, however, they possess modest cytotoxicity against the MCF-7 (human breast cancer) and triple-negative breast cancer (TNBC) (MDA- MB-231 breast cancer cells), and the rate of killing cancer cells strongly depends on the dose of mCNCs. Further, the mitochondrial membrane potential and apoptosis assay were performed to analyze the therapeutic significance of these nanocapsules to kill breast cancer. Results showed that these carbon nanocapsules can depolarize the mitochondrial membrane potential alone (without using conventional drugs) and can change the physiological parameters and cellular metabolic energy of the cancer cells and kill them. The apoptosis results confirmed the death of breast cancer cells in the form of apoptosis and necrosis. Moreover, the results suggested that the porous carbon nanocapsules (mCNCs) reported herein can be used as a potential candidate and useful for the theranostic applications such as for cancer cell detection and therapy without using any conventional drugs.
