Autophagy inhibition could hinder the underlying protective mechanisms in course of tumor treatment. The advances autophagy have driven focus on functionalized nanoplatforms by combining current treatment paradigms with complementary for enhanced efficacy. Furthermore, Ca2+ overload is also a promising adjuvant target augmenting mitochondrial damage. In this view, and were first demonstrated as novel strategy suitable homing shortage photodynamic therapy (PDT). We constructed biodegradable tumor-targeted inorganic/organic hybrid nanocomposites (DPGC/OI) synchronously encapsulating IR780 Obatoclax biomineralization nanofilm method, which consists pH-triggered calcium phosphate (CP), long circulation phospholipid block copolymers 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE)-poly(ethylene glycol) (PEG)2000-glucose (DPG). presence hydrophilic PEG chain glucose transporter 1 (Glut-1) ligands, DPGC would become an effectively tumor-oriented nanoplatform. Subsequently, outstanding photosensitizer produce increased amounts toxic reactive oxygen species (ROS) after laser irradiation. Calcium (CP) nanogenerator generate at low pH to induce overload. dysfunction mitochondria enhance ROS. Based premise that degrade dysfunctional organelles sustain metabolism homeostasis, might participate resistance PDT, inhibitor mechanism from cancer cells negligible toxicity. Such PDT via be realized DPGC/OI.

Breast cancer (BC) is the most prevalent in women. BC heterogeneous, with distinct phenotypical and morphological characteristics. These are based on their gene expression profiles, which divide into different subtypes, among triple-negative breast (TNBC) subtype aggressive one. The growing interest tumor metabolism emphasizes role of altered glucose driving progression, response to treatment, its therapy resistance. Alterations characterized by increased uptake glucose, hyperactivated glycolysis, decreased oxidative phosphorylation (OXPHOS) component, accumulation lactate. deviations attributed upregulation key glycolytic enzymes transporters metabolic pathway. Key such as hexokinase, lactate dehydrogenase, enolase upregulated, thereby conferring resistance towards drugs cisplatin, paclitaxel, tamoxifen, doxorubicin. Besides, drug efflux detoxification two energy-dependent mechanisms contributing emergence chemotherapy can occur at an early or later stage thus limiting success outcome therapy. Therefore, understanding aberrant tumors link essential. Using combinatory treatment inhibitors, for example, 2-deoxy-D-glucose (2-DG) metformin, showed promising results countering Newer designs conjugated sugars peptides that utilize enhanced cell offer selective efficient delivery cells less toxicity healthy cells.

Although chemotherapy can improve the overall survival and prognosis of cancer patients, chemoresistance remains an obstacle due to diversity, heterogeneity, adaptability environmental alters in clinic. To determine more possibilities for therapy, recent studies have begun explore changes metabolism, especially glycolysis. The Warburg effect is a hallmark that refers preference cells metabolize glucose anaerobically rather than aerobically, even under normoxia, which contributes chemoresistance. However, association between glycolysis molecular mechanisms glycolysis-induced unclear. This review describes mechanism from aspects process, signaling pathways, tumor microenvironment, their interactions. understanding how induces may provide new targets concepts therapy.

Abstract Mitochondria are essential cellular organelles that involved in regulating energy, metabolism, survival, and proliferation. To some extent, cancer is a genetic metabolic disease closely associated with mitochondrial dysfunction. Hypoxia-inducible factors (HIFs), which major molecules respond to hypoxia, play important roles development by participating multiple processes, such as proliferation, angiogenesis. The Warburg phenomenon reflects pseudo-hypoxic state activates HIF-1α. In addition, product of the effect, lactate, also induces However, proposed aerobic glycolysis occurs due defect mitochondria.

Abstract Second near‐infrared (NIR‐II) fluorescence imaging with deep tissue‐penetration ability holds remarkable potential for cancer diagnosis. However, clinical translation of NIR‐II imaging‐based treatment is severely restricted by the low signal‐to‐background ratio due to insufficient tumor specificity fluorophores. In this study, it hypothesized that methylglyoxal (MGO), an intermediate metabolite glycolysis could be used as a potent biomarker triggering imaging‐guided theranostic. For proof‐of‐concept, first MGO‐activatable probe developed, and then MGO‐responsive “dual lock‐and‐key” nanotheranostics integrating fluorophore photodynamic prodrug (i.e., hexyl 5‐aminolevulinic acid hydrochloride (HAL)) into one nanoparticle engineered. The nanotheranostic can specifically activated tumorous MGO combinatory therapy. Upon 808 nm laser irradiation, generate tunable photothermal effect trigger HAL release.
