Mitochondrial inner membrane in hypothyroidism [PDF]

open access: yesArchives of Biochemistry and Biophysics, 1976
Abstract Inner membrane vesicles obtained from the liver mitochondria of hypothyroid and normal rats were compared. In the vesicles from hypothyroid rats the rate of ATP synthesis at 30 °C is 35–50% less than the normal rate. The Arrhenius profile for phosphorylation by such vesicles lacks the discontinuity at 21 °C that is seen with vesicles from ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Electron Microscope Study Of Mitochondrial 60S and Cytoplasmic 80S Ribosomes From Locusta Migratoria [PDF]

open access: yes, 1974
Purified mitochondrial ribosomes (60S) have been isolated from locust flight muscle. Purification could be achieved after lysis of mitochondria in 0.055 M MgCl2.

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Transport of proteins into mitochondria [PDF]

open access: yes, 1985
Translocational intermediates of precursor proteins of ATPase F1β subunit and cytochrome c1 across mitochondrial membranes were analyzed using two different approaches, transport at low temperature and transport after binding of precursor proteins to ...

The relevance of mitochondrial membrane topology to mitochondrial function

open access: yesBiochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2006
This review summarizes recent findings from electron tomography about the three-dimensional shape of mitochondrial membranes and its possible influence on a range of mitochondrial functions. The inner membrane invaginations called cristae are pleomorphic, typically connected by narrow tubular junctions of variable length to the inner boundary membrane.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

CancerGram: An Effective Classifier for Differentiating Anticancer from Antimicrobial Peptides

open access: yesPharmaceutics, 2020
Antimicrobial peptides (AMPs) constitute a diverse group of bioactive molecules that provide multicellular organisms with protection against microorganisms, and microorganisms with weaponry for competition.

Unique and abnormal subependymal pseudocysts in a newborn with mitochondrial disease

open access: yesScience Progress, 2021
Neonatal mitochondrial disease is occasionally observed in patients with intraventricular cysts in the brain. Atypical morphology is rarely seen in these cysts. Here, we report a case of neonatal lethal mitochondrial disease with IBA57 gene mutation.

Mitochondrial outer membrane permeabilization: a focus on the role of mitochondrial membrane structural organization [PDF]

open access: yesBiophysical Reviews, 2017
Apoptosis is important in regulating cell death turnover and is mediated by the intrinsic and death receptor-based extrinsic pathways which converge at the mitochondrial outer membrane (MOM) leading to mitochondrial outer membrane permeabilization (MOMP).
