Rearranged during transfection (RET) rearrangements occur in 1% to 2% of lung adenocarcinomas as well other malignancies and are now established targets for tyrosine kinase inhibitors. We developed three novel RET fusion–positive (RET+) patient–derived cancer cell lines, CUTO22 [kinesin 5B (KIF5B)–RET fusion], CUTO32 (KIF5B-RET fusion), CUTO42 (e...

CONTEXT Vietnam has experienced a rapid fertility decline over the last three decades, yet fertility rates vary considerably across the country's 54 ethnic groups. METHODS Data were drawn from the 2001 Vietnam National Health Survey, which collected information from 27,097 currently married women aged 15-49 on their birth and abortion history over the preceding five years, as well as their cu...

Kinesin motors drive the long-distance anterograde transport of cellular components along microtubule tracks. Kinesin-dependent transport plays a critical role in neurogenesis and neuronal function due to the large distance separating the soma and nerve terminal. The fate of kinesin motors after delivery of their cargoes is unknown but has been postulated to involve degradation at the nerve ter...

Autophagy is a lysosome-dependent degradation process that is essential for maintaining cellular homeostasis. In recent years, more studies have focused on the late stages of autophagy. Our group discovered and studied the terminal step of autophagy, namely autophagic lysosome reformation (ALR). ALR is the process that regenerates functional lysosomes from autolysosomes, thus maintaining lysoso...

Stress granules (SGs) and P-bodies (PBs) are related cytoplasmic structures harboring silenced mRNAs. SGs assemble transiently upon cellular stress, whereas PBs are constitutive and are further induced by stress. Both foci are highly dynamic, with messenger ribonucleoproteins (mRNPs) and proteins rapidly shuttling in and out. Here, we show that impairment of retrograde transport by knockdown of...

Distinct molecules are segregated into somatodendritic and axonal compartments of polarized neurons, but mechanisms underlying the development and maintenance of such segregation remain largely unclear. In cultured hippocampal neurons, we observed an ankyrin G- and F-actin-dependent structure that emerged in the cytoplasm of the axon initial segment (AIS) within 2 days after axon/dendrite diffe...
