Myeloid deletion and therapeutic activation of AMPK do not alter atherosclerosis in male or female mice

21 views | Oct 02 2020

Nicholas D LeBlond et al. suggested that intervention with the first-generation AMPK activator A-769662 was not able to stem the progression of atherosclerosis. [Read the Full Post]

Irisin ameliorates high glucose-induced cardiomyocytes injury via AMPK/mTOR signal pathway

73 views | Aug 10 2020

Jingyu Deng et al. showed that Irisin played a significant role in anti-apoptosis, anti-inflammation, anti-oxidative stress in HG-induced CMs via AMPK/mTOR signaling pathway. [Read the Full Post]

Pentraxin-3 Mediates Prosurvival Actions of Interferon Tau in Bovine Luteinized Granulosa Cells

70 views | Aug 06 2020

Raghavendra Basavaraja et al. suggested a novel role for PTX3 during early pregnancy, as mediator of IFNT prosurvival actions supporting CL maintenance during this reproductive stage. [Read the Full Post]

Cell Cycle Arrest and Apoptosis Are Not Dependent on p53 Prior to p53-dependent Embryonic Stem Cell Differentiation

235 views | Jun 02 2020

Sushil K Jaiswal et al. found that the multiple roles of p53 in cell cycle regulation and apoptosis were first acquired during pluripotent stem cell differentiation. [Read the Full Post]

Bcl-2high mantle cell lymphoma cells are sensitized to acadesine with ABT-199

104 views | Mar 23 2020

Montraveta A et al. supported the notions that antiapoptotic proteins of the Bcl-2 family regulate MCL cell sensitivity to acadesine and that the combination of this agent with Bcl-2 inhibitors might be an interesting therapeutic option to treat MCL patients. [Read the Full Post]

Biguanides Induce Acute de novo Lipogenesis in Human Primary Sebocytes

99 views | Mar 22 2020

Nicoll J et al. found that biguanides, isotretinoin and azithromycin induced an acute dose and time-dependent increase in [14C]-acetate labeling of neutral lipids, while AICAR, an AMPK activator, inhibited this DNL response. Biguanides did not activate AMPK in sebocytes, however, they significantly reduced oxygen consumption rate and increased lactate production. Treatment with biguanides, but not isotretinoin, significantly upregulated ACSS2 gene expression in primary sebocytes and showed synergism with lipogenic activators to induce DNL genes.

Effect of A-769662, a direct AMPK activator, on Tlr-4 expression and activity in mice heart tissue

213 views | Dec 09 2019

Rameshrad M et al. demonstrated that activation of AMPK, by A-769662 agent, could inhibit Tlr-4 expression and activity, suggesting a link between AMPK and Tlr-4 in heart tissue. [Read the Full Post]

Dorsomorphin induces cancer cell apoptosis and sensitizes cancer cells to HSP90 and proteasome inhibitors by reducing nuclear heat shock factor 1 levels

140 views | Oct 19 2019

Li N et al. indicated that dorsomorphin is an HSF1 inhibitor. It induces cancer cell apoptosis, sensitizes cancer cells to both HSP90 and proteasome inhibitors, and suppresses HSP upregulation by these drugs, which may prevent the development of drug resistance. Hence, dorsomorphin and its derivates may serve as potential precursors for developing drugs against cancer. [Read the Full Post]

AMP-activated protein kinase (AMPK) activator A-769662 increases intracellular calcium and ATP release from astrocytes in an AMPK-independent manner

386 views | May 23 2019

Vlachaki Walker JM et al. indicated that AMPK is required to maintain basal eATP levels but is not required for A-769662-induced increases in eATP. A-769662 (>50 μM) enhanced intracellular calcium levels leading to ATP release in an AMPK and purinergic receptor independent pathway. [Read the Full Post]

Compound C induces protective autophagy in human cholangiocarcinoma cells via Akt/mTOR-independent pathway

211 views | Mar 08 2019

Zhao X et al. demonstrated that compound C inhibited the phosphorylation of JNK and its target c-Jun. Blocking JNK by SP600125 or siRNA suppressed autophagy induction upon compound C treatment. Moreover, compound C induced p38 MAPK activation, and its inhibition promoted autophagy induction via JNK activation. In addition, compound C induced p53 expression, and its inhibition attenuated compound C-induced autophagic response. Thus, compound C triggers autophagy, at least in part, via the JNK and p53 pathways in human CCA cells. In conclusion, suppresses autophagy could increase compound C sensitivity in human CCA.
