The effects of intensive lipid lowering (LDL-C of <1.

KMT2D Deficiency Promotes Myeloid Leukemias which Is Vulnerable to Ribosome Biogenesis Inhibition.

KMT2C and KMT2D are the most frequently mutated epigenetic genes in human cancers. While KMT2C is identified as a tumor suppressor in acute myeloid leukemia (AML), the role of KMT2D remains unclear in this disease, though its loss promotes B cell lymphoma and various solid cancers. Here, it is reported that KMT2D is downregulated or mutated in AML and its deficiency, through shRNA knockdown or CRISPR/Cas9 editing, accelerates leukemogenesis in mice.

DNMT3A accelerates angioimmunoblastic T-cell lymphoma in mice.

DNA methylation-related genes, including TET2, IDH2, and DNMT3A are highly frequently mutated in angioimmunoblastic T-cell lymphoma (AITL), an aggressive malignancy of T follicular helper (Tfh) cells associated with aberrant immune features. It has been shown that TET2 loss cooperates with RHOA to promote AITL in mice but the functional role of DNMT3A mutations in AITL remains unclear. Here, we report that DNMT3A, the most common mutation of DNMT3A in AITL, accelerates the development of Tet2; RHOA AITL in mice, indicated by the expansion of malignant Tfh cells and aberrant B cells, skin rash, and significantly shortened disease-free survival.

Light-emitting diodes (LEDs) are the 4th plant supplemental lighting source. Pulsed lighting is benefit to increase energy utilization efficiency in greenhouse production. A pulsed-lighting LED luminaire with geometrical optical solution is proposed to overcome the shortcoming with pulse width modulation (PWM) solution.

Exceptional terrestrial warmth around 4200-2800 years ago in Northwest China.

One of the Holocene abrupt events around 4200 years ago, lasting for ∼ 200 years, is thought to have caused cultural disruptions, yet terrestrial climatic status right after the cold/dry event remains poorly defined and is often presumed that a generally cool condition prevailed during the Bronze Age (∼ 4000-2200 years ago). Here we report an alkenone-based summer temperature record over the past ∼ 12,000 years, in addition to two updated alkenone records, from Northwest China, providing new insights into the climatic status right after the event. Our results indicate that exceptional terrestrial warmth, up to ∼ 6 °C, occurred around 4200-2800 years ago during the Bronze Age, superimposed on the long-term Holocene cooling trend.

Fractal analysis on CO hydrate-bearing sands during formation and dissociation processes with NMR.

Injecting CO into submarine sediments to form hydrates is one of the potential methods of CO sequestration. The transition behavior of CO hydrates in porous media is of great practical significance. In this work, CO hydrate formation/dissociation in porous media was monitored in real time by a low-field magnetic resonance (MR) system, and a series of dynamic fractal dimensions of the pore space occupied by converted water during the hydrate formation/dissociation process were obtained based on the transverse relaxation time (T) distributions.

Dissecting the genetic and microenvironmental factors of gastric tumorigenesis in mice.

Gastric cancer (GC) is one of the most frequent and lethal malignancies in the world. However, our understanding of the mechanisms underlying its initiation and progression is limited. Here, we generate a series of primary GC models in mice with genome-edited gastric organoids, which elucidate the genetic drivers for sequential transformation from dysplasia to well-differentiated and poorly differentiated GC.

Acquired semi-squamatization during chemotherapy suggests differentiation as a therapeutic strategy for bladder cancer.

Cisplatin-based chemotherapy remains the primary treatment for unresectable and metastatic muscle-invasive bladder cancers (MIBCs). However, tumors frequently develop chemoresistance. Here, we established a primary and orthotopic MIBC mouse model with gene-edited organoids to recapitulate the full course of chemotherapy in patients.

Simultaneous determination of oxalate and citrate in urine and serum of calcium oxalate kidney stone rats by IP-RP LC-MS/MS.

Oxalate and citrate in 24 h urine and serum are considered to be associated with the incidence and recurrence risk of calcium oxalate kidney stones. The quantification of oxalate and citrate contributes to understand the pathological metabolism of kidney stones and guide the early diagnosis and recurrence monitoring. Although simultaneous quantification of oxalate and citrate in urine using liquid chromatography tandem mass spectrometry (LC-MS/MS) have been reported, the optimization of chromatographic column, mobile phase and mass spectrometry (MS) parameters has not been performed.

KMT2C deficiency promotes small cell lung cancer metastasis through DNMT3A-mediated epigenetic reprogramming.

Small cell lung cancer (SCLC) is notorious for its early and frequent metastases, which contribute to it as a recalcitrant malignancy. To understand the molecular mechanisms underlying SCLC metastasis, we generated SCLC mouse models with orthotopically transplanted genome-edited lung organoids and performed multiomics analyses. We found that a deficiency of KMT2C, a histone H3 lysine 4 methyltransferase frequently mutated in extensive-stage SCLC, promoted multiple-organ metastases in mice.

Combined metabolomics with transcriptomics reveals potential plasma biomarkers correlated with non-small-cell lung cancer proliferation through the Akt pathway.
