HOXB8 mediates resistance to cetuximab in colorectal cancer cells through activation of the STAT3 pathway.

Homeobox B8 (HOXB8) belongs to the HOX family and was essential to the development of colorectal carcinoma. Among the prevalent monoclonal antibodies for treating RAS/BRAF wild-type metastatic colorectal cancer (mCRC) patients, cetuximab stands out, but resistance to cetuximab frequently arises in targeted treatments. Currently, the role of HOXB8 in cetuximab-resistant mCRC remains unclear.

SLC25A19 is required for NADH homeostasis and mitochondrial respiration.

Mitochondrial transporters facilitate the translocation of metabolites between the cytoplasm and mitochondria and are critical for mitochondrial functional integrity. Although many mitochondrial transporters are associated with metabolic diseases, how they regulate mitochondrial function and their metabolic contributions at the cellular level are largely unknown. Here, we show that mitochondrial thiamine pyrophosphate (TPP) transporter SLC25A19 is required for mitochondrial respiration.

Naringenin relieves paclitaxel-induced pain by suppressing calcitonin gene-related peptide signalling and enhances the anti-tumour action of paclitaxel.

Background And Purpose: Chemotherapy-induced peripheral neuropathy (CIPN) commonly causes neuropathic pain, but its pathogenesis remains unclear, and effective therapies are lacking. Naringenin, a natural dihydroflavonoid compound, has anti-inflammatory, anti-nociceptive and anti-tumour activities. However, the effects of naringenin on chemotherapy-induced pain and chemotherapy effectiveness remain unexplored.

The deposition and significance of an Ediacaran non-glacial iron formation.

Most Neoproterozoic iron formations (NIF) are closely associated with global or near-global "Snowball Earth" glaciations. Increasingly, however, studies indicate that some NIFs show no robust evidence of glacial association. Many aspects of non-glacial NIF genesis, including the paleo-environmental setting, Fe(II) source, and oxidation mechanisms, are poorly understood.

Mechanisms underlying paclitaxel-induced neuropathic pain: Channels, inflammation and immune regulations.

Paclitaxel is a chemotherapeutic agent widely used for many types of malignancies. However, when paclitaxel is used to treat tumors, patients commonly experience severe neuropathic pain that is difficult to manage. The mechanism underlying paclitaxel-induced neuropathic pain remains unclear.

In-cytoplasm mitochondrial transplantation for mesenchymal stem cells engineering and tissue regeneration.

Stem cell therapies are unsatisfactory due to poor cell survival and engraftment. Stem cell used for therapy must be properly "tuned" for a harsh in vivo environment. Herein, we report that transfer of exogenous mitochondria (mito) to adipose-derived mesenchymal stem cells (ADSCs) can effectively boost their energy levels, enabling efficient cell engraftment.

Matrine inhibits cell growth, migration, invasion and promotes autophagy in hepatocellular carcinoma by regulation of circ_0027345/miR-345-5p/HOXD3 axis.

Background: Matrine has been reported to exert anti-tumor effects in multiple types of cancers containing hepatocellular carcinoma (HCC). However, the anti-tumor molecular mechanisms of matrine in HCC is still not fully revealed.

Methods: Cell viability, apoptosis, cycle, migration and invasion were determined by Cell counting kit-8 (CCK-8), Flow cytometry and Transwell assays, respectively.

Extracellular Vesicles: A New Perspective in Tumor Therapy.

In recent years, the study of extracellular vesicles has been booming across various industries. Extracellular vesicles are considered one of the most important physiological endogenous carriers for the specific delivery of molecular information (nucleonic acid, cytokines, enzymes, etc.) between cells.

Epithelial-mesenchymal transition: potential regulator of ABC transporters in tumor progression.

Epithelial-mesenchymal transition (EMT) can directly contribute to some malignant phenotypes of tumor cells including invasion, metastasis and resistance to chemotherapy. Although EMT is widely demonstrated to play a critical role in chemoresistance and metastasis, the potential signaling network between EMT and drug resistance is still unclear. The distribution of drugs in the internal and external environment of the tumor cells is tightly linked with ATP-binding cassette (ABC) transporters.
