Exploration of Site-Specific Drug Targeting-A Review on EPR-, Stimuli-, Chemical-, and Receptor-Based Approaches as Potential Drug Targeting Methods in Cancer Treatment.

Cancer has been one of the most dominant causes of mortality globally over the last few decades. In cancer treatment, the selective targeting of tumor cells is indispensable, making it a better replacement for conventional chemotherapies by diminishing their adverse side effects. While designing a drug to be delivered selectively in the target organ, the drug development scientists should focus on various factors such as the type of cancer they are dealing with according to which drug, targeting moieties, and pharmaceutical carriers should be targeted.

The regulatory networks and mechanisms of bone microenvironment in tumorigenesis and metastasis.

Bone tumors, encompassing heterogeneous primary and metastatic lesions, are driven in their initiation, progression, and metastasis by dysregulation of the bone microenvironment (BME). Clinically manifested by localized pain, pathological fractures, and neurological deficits, these malignancies substantially threaten patient survival. Radiographic patterns (osteolytic, osteoblastic, mixed) directly reflect pathogenic BME-tumor interactions, particularly involving osteoblast-osteoclast imbalance. The BME-a specialized niche of bone-resident cells (osteocytes, osteoblasts, osteoclasts), immune c

Impact of preoperative anemia on outcomes in patients undergoing curative resection for gastric cancer: a single-institution retrospective analysis of 2163 Chinese patients.

We sought to evaluate whether preoperative anemia was an important determinant of survival in gastric cancer (GC). A single institution cohort of 2163 GC patients who underwent curative resection were retrospectively analyzed. Anemia was defined as a preoperative hemoglobin level <120 g/L in males and <110 g/L in females. Overall survival (OS) was analyzed using the Kaplan-Meier method, and a multivariate Cox proportional hazards model was performed to identify the independent prognostic factor. Anemic patients had a poorer OS compared with nonanemic patients after resection for tumor-nodes-me

Chemokines and their receptors in oral squamous cell carcinoma: mechanisms, clinical significance, and therapeutic implications.

Chemokines, a category of cytokines exhibiting chemotactic properties, have been thoroughly investigated as targets in cancer treatment in recent decades. In oral squamous cell carcinoma (OSCC), a prevalent and high-risk malignancy of the head and neck, chemokines interact with their specific receptors to initiate downstream signaling pathways. This signaling influences not only tumor cell proliferation, migration, invasion, and metastasis of oral cancer cells but also angiogenesis and vascular maturation. Furthermore, they modulate the tumor microenvironment (TME), which consists of diverse c

Rare Diseases of the Orbit.

This article provides an overview of rare orbital diseases. Congenital malformations, inflammatory diseases, benign and malignant neoplasias are described. Although it represents a relatively small area of the body the orbit contains multiple different tissues. Therefore, a great variety of diseases can be found within the orbital space. That is the reason, why both the completeness and the level of detail in the description of particular diseases must be somewhat limited. Nevertheless, clinical manifestations, important aspects of diagnosis, treatment strategies, and, when specific data are a

Metabolic reprogramming and therapeutic resistance in primary and metastatic breast cancer.

Metabolic alterations, a hallmark of cancer, enable tumor cells to adapt to their environment by modulating glucose, lipid, and amino acid metabolism, which fuels rapid growth and contributes to treatment resistance. In primary breast cancer, metabolic shifts such as the Warburg effect and enhanced lipid synthesis are closely linked to chemotherapy failure. Similarly, metastatic lesions often display distinct metabolic profiles that not only sustain tumor growth but also confer resistance to targeted therapies and immunotherapies. The review emphasizes two major aspects: the mechanisms driving
